    Final Order.
    Order of the Board
    (by J.
    Anderson):
    Pursuant to Sections 17.5 of the Environmental Protection
    Act
    (Act), the Board is proposing to amend the Safe Drinking
    Water Act
    (SDWA)
    regulations.
    Section 17.5 provides for quick adoption of regulations
    which are “identical in substance” to federal regulations and
    that Title VII of the Act and Section 5 of the Administrative
    Procedure Act
    (APA)
    shall not apply.
    Because this rulemaking is
    not subject to Section
    5 of the APA,
    it is not subject to first
    notice or to second notice review by the Joint Committee on
    Administrative Rules
    (JCAR).
    The federal SDWA regulations are
    found at 40 CFR 141 and 142.
    This rulemaking updates SDWA rules
    to correspond with major federal amendments more fully outlined
    in the accompanying Opinion.
    This proposed order
    is supported by a proposed opinion
    adopted on the same day.
    The Board will receive public comment
    on the proposal for a period of 45 days following its publication
    in the Illinois Register.
    The complete text of the proposed
    rules follows.
    IT IS SO ORDERED.
    I, Dorothy N. Gunn,
    Clerk of the Illinois Pollution Control
    Board, do hereby certify that the above order was adopted on the
    __________

    Special Exception Permits
    a)
    Unless otherwise specified, each Agency determination
    in this Part is to be made by way of a written permit
    pursuant to Section 39(a)
    of the Act.
    Such permit is
    titled a “special exception” permit

    its
    discretion
    and
    initiate
    a
    SEP
    pursuant to subsection
    (d)
    (2)
    above.
    Rather, the
    Board
    intends
    to
    clarify
    by

    to
    initiate
    a
    SEP
    without
    receiving
    a
    request
    from
    the
    supplier.
    e)
    The Agency shall evaluate a request for a SEP from the
    monitoring requirements of Section 611.646(e)

    knowledge of previous use (including transport,
    storage, or disposal)
    of the contaminant in the
    watershed or zone of
    influence of the system,
    as
    determined pursuant to 35
    Ill.
    Adm. Code 671:
    1)
    If the Agency determines that there was no prior
    use
    of
    the
    contaminant,
    it
    shall
    grant
    the
    SEP,
    or
    2)
    If the contaminant was previously used or the
    previous use was unknown, the Agency shall
    consider the following factors:
    A)
    Previous analytical results;
    B)
    The
    proximity
    of
    the
    system
    to
    any
    possible
    point source of contamination (including
    spills or leaks at or near a water treatment
    facility; at manufacturing, distribution, or
    storage facilities; from hazardous and
    municipal waste land fills; or from waste
    handling or treatment facilities)
    or non-
    point source of contamination
    (including the
    use of pesticides and other land application
    uses of the contaminant);
    C)
    The environmental persistence and transport
    of the contaminant;
    D)
    How well the water source is protected
    against contamination, including whether it
    is
    a
    SWS
    or
    a
    GWS:
    1)

    Section 1415 Variances
    This Section is intended as a State equivalent of Section
    1415(a) (1) (A)
    of the SDWA.
    a)
    The Board may grant a supplier a variance from a NPDWR
    in this Part.
    1)
    The supplier shall file a variance petition
    0
    L~2-(J165

    36
    pursuant to
    35 Ill.
    Adm. Code 104,
    except as
    modified or supplemented by this Section.
    2)
    The Board may grant a variance from the additional
    State requirements in this Part without following
    this Section.
    b)
    As part of the showing of arbitrary or unreasonable
    hardship, the supplier shall demonstrate that:
    1)
    Because of characteristics of the raw water
    sources that are reasonably available to the
    system, the supplier cannot meet the MCL or other
    requirement; and
    2)
    The system has applied BAT as identified in
    Subpart G of this Part.
    BAT may vary depending
    on:
    A)
    The number of persons served by the system;
    B)
    Physical conditions related to engineering
    feasibility; and
    C)
    Costs
    of compliance; and
    3)
    The
    variance will not result in an unreasonable
    risk to health,
    as defined
    in subsection
    (g)
    below.
    c)
    The Board will prescribe a schedule for:
    1)
    Compliance,
    including increments
    of progress,
    by
    the
    supplier, with each MCL or other requirement
    with respect to which the variance was granted,
    and
    2)
    Implementation by the supplier of each additional
    control measure for each MCL or other requirement,
    during the period ending on the date compliance
    with such requirement is required.
    d)
    A schedule of compliance will require compliance with
    each MCL or other requirement with respect to which the
    variance was granted as expeditiously as practicable.
    e)
    The Board will provide notice and opportunity for a
    public hearing as provided in 35
    Ill.
    Adm.
    Code
    104.
    f)
    The
    Board will not grant a-variance:
    1)
    From the MCL
    for total coliforms; provided,
    ~
    F)
    -

    -

    37
    however, that the Board may grant
    a variance from
    the total coliform MCL of Section 611.325 for PWSs
    that demonstrate that the violation
    of the total
    coliform MCL is due to persistent growth of total
    coliforms in the distribution system,
    rather than
    from fecal or pathogenic contamination,
    from a
    treatment
    lapse or deficiency, or from a problem
    in the operation or maintenance of the
    distribution system.
    2)
    Or,
    from
    any of the treatment technique
    requirements of Subpart B of this Part.
    g)
    As used in this Section and Section 611.112,
    “unreasonable risk to health level”
    (“URTH level”)
    means the concentration of a contaminant that will
    cause a serious health effect within the period of time
    specified in the variance or exemption requested by a
    supplier seeking to come into compliance by installing
    the treatment required to reduce the contaminant to the
    MCL.
    URTH level determinations are made on the basis
    of the individual contaminant,
    taking into account:
    the degree by which the level exceeds the MCL; duration
    of exposure; historical data; and population exposed.
    A risk to health is assumed to be unreasonable unless
    the supplier demonstrates that there are costs
    involved
    that
    clearly
    exceed
    the
    health benefits to be derived.

    Relief from the TTHM NCL.
    fl
    In granting any variance or adlusted standard to a
    supplier that is a CWS that adds a disinfectant at

    10,000 or more persons on
    a regular basis from the

    identified at subsection
    (a) (4)
    below for that
    constituent as a condition to the relief, unless
    the supplier has demonstrated through
    comprehensive engineering assessments that
    application of BAT is not technically appropriate

    C)
    The supplier
    shall develop
    a monitoring plan before
    point—of-entry devices are installed for compliance.
    1)
    Point—of-entry devices must provide health
    protection equivalent to central water treatment.
    “Equivalent” means that the water would meet all
    NPDWR
    and would be of acceptable quality similar
    to water distributed by a well-operated central
    treatment plant.
    2)
    In addition to the VOCs, monitoring must include
    physical
    measurements and observations such as
    total flow treated and mechanical condition of the
    treatment equipment.
    3)
    Use of point-of-entry devices must be approved by
    spccial cxccption pcrmita SEP granted by the
    Agency pursuant to Section 611.110.
    d)
    Effective technology must be properly applied under a
    plan approved by the Agency and the microbiological
    safety of the water must be maintained.
    1)
    The Agency shall require adequate certification of
    performance, field testing,
    and,
    if not included
    in the certification process,
    a rigorous
    engineering design review of the point-of—entry
    devices.
    2)
    The design and application of the point-of-entry
    devices must consider the tendency for increase in
    heterotrophic bacteria concentrations in water
    treated with activated carbon.
    The Agency may
    require, by special exception permit,
    frequent
    backwashing, post-contactor disinfection and HPC
    monitoring to ensure that the microbiological
    safety of the water is not compromised.
    e)
    All consumers must be protected.
    Every building
    connected to the system must have a point—of—entry

    Applicability.
    The requirements of this Subpart
    constitute national primary drinking water
    regulations for lead and copper.
    This Subpart
    applies to all community water systems
    (CWSs)
    and
    non—transient, non—community water systems
    (NTNCWSs).
    21
    Score.
    This Subpart establishes a treatment
    technique that includes requirements for corrosion
    control treatment,
    source water treatment,
    lead
    service line replacement, and public education.
    These requirements are triggered,
    in some cases,
    bY lead and copper action levels measured in
    samples collected at consumers’ taps.
    ~j
    Definitions.
    For the purposes of only this Subpart,
    the following terms shall have the following meanings:
    “Action level” means that concentration of lead or
    copper in water computed Pursuant to subsection
    (c)
    below that determines,
    in some cases, the
    treatment requirements
    of this
    Subpart which a
    supplier must complete.
    The action level for lead
    is 0.015 mg/L.
    The action level for copper
    is 1.3
    mg/L.
    “Corrosion inhibitor” means a substance capable of
    reducing the corrosivity of water toward metal
    plumbing materials, especially lead and copper, by
    forming a protective film on the interior surface
    of those materials.
    “Effective corrosion inhibitor residual” means a
    concentraU~n
    of inhibitor in the drinking water
    sufficient to form a ~assivating film on the
    interior walls of
    a pipe.
    “Exceed”,
    as this term is applied to either the
    lead or the copter action level, means that the
    90th percentile level of the supplier’s samples
    collected during a six—month monitoring period is
    ~reater than the action level for that
    contaminant.
    “First draw sample” means a one—liter sample of
    ta~water, collected in accordance with Section
    611.356(b) (2), that has been standing in plumbing
    pipes for at least
    6 hours and which is collected
    without flushing the tap.
    “Large system” means a water system that regularly
    serves water to more than 50,000 persons.

    56
    “Lead service line”,
    means a service line made of
    lead that connects the water main to the building
    inlet,
    including any lead pigtail, gooseneck,
    or
    other fitting that is connected to such lead line.
    “Maximum permissible concentration” or “MPC” means
    that concentration of lead or copper for finished
    water entering the supplier’s distribution system,
    designated by the Agnecy by a SEP Pursuant to
    Sections 611.110 and 611.353(b)
    that reflects the
    contaminant removal capability of the treatment
    properly operated and maintained.
    BOARD NOTE:
    Derived from 40 CFR 141.83(b) (4)
    (1992)
    (Section 611.353(b) (4) (B)).
    “Medium—sized system” means
    a water system that
    regularly serves water to more than 3,300 up to
    50,000 or fewer persons.
    “Meet”,
    as this term is applied to either the lead
    or the copper action level,
    means that the 90th
    percentile level of the supplier’s samples
    collected during a six—month monitoring period
    is
    less than or equal to the action level for that
    contaminant.
    “Method detection limit” or “MDL”
    is as defined at
    Section 611.646(a).
    The MDL for lead is 0.001
    mg/L.
    The MDL for copper is 0.001 mg/L,
    or 0.020
    m~JL
    by atomic absorption direct aspiration
    method.

    “Monitoring period” means any of the six—month
    periods of time during which a supplier must
    complete
    a
    cycle
    of
    monitoring
    under
    this
    Subpart.
    BOARD NOTE:
    USEPA refers to these as “monitoring
    periods”.
    The Board uses “six—month monitoring
    period” to avoid confusion with “compliance
    period”, as used elsewhere in this Part and
    defined at Section 611.101.
    “Multiple-family residence” means a building that
    is currently used as a multiple—family residence~
    but not one that is also a “single-family
    structure”.
    “90th percentile level” means that concentration
    of lead or copper contaminant exceeded by 10
    percent or fewer of all samples collected during a
    six—month monitoring period Pursuant to Section

    BOARD
    NOTE:
    Derived
    from
    40
    CFR 141.80(c)
    (1992).
    “Optimal corrosion control treatment” means the
    corrosion control treatment that minimizes the
    lead and copper concentrations at users’ taps
    while ensuring that the treatment does not cause
    the water system to violate any national primary
    drinking
    water
    regulations.
    “Practical quantitation limit” or “POL” means the
    lowest concentration of a contaminant that a well—
    operated laboratory can reliably achieve within
    specified limits of precision and accuracy during
    routine laboratory operating conditions.
    The PQL
    for lead is 0.005 mg/L.
    The POL for copper
    is
    0.050
    mg/L.

    USEPA has generally defined the POL
    as
    5 to 10 times the method detection limit.
    “Service line sample” means a one—liter sample of
    water, collected in accordance with Section
    611.356(b) (3). that has been standing for at least

    List the results of all lead or copper
    samples taken during a six—month monitoring
    period in ascending order, ranging from the
    sample with the lowest concentration first to
    the sample with the highest concentration
    last.
    Assign each sampling result a number,
    ascending by single integers beginning with
    the number
    1 for the sample with the lowest
    contaminant level.
    The number assigned to
    the sample with the highest contaminant level
    shall be equal to the total number of samples
    taken.
    ~j
    Determine the number for the 90th percentile
    sample by multiplying the total number of
    samples taken during the six—month monitoring
    period by 0.9.
    ~
    The contaminant concentration’ in the sample
    with the number yielded by the calculation in
    subsection
    (c) (3) (B)
    above
    is the 90th
    percentile contaminant level.
    Qj
    For suppliers that collect
    5 samples per six-

    Under Section 611.354(e) (1).
    a supplier
    is presumed to control the entire
    service line unless it makes an affirmative
    showing.
    Under Section 611.354(d) (2) (A), a
    supplier is affirmatively required to replace
    all of each service line except as to
    any
    particular service line for which the Aaency
    has made an affirmative determination that
    the supplier does not control in its
    entirety.
    Under Sections 611.354(b) (1) and
    (b) (4), the supplier must have completed
    replacing seven Percent of the lead service
    lines within a year of the day of the event
    that_triggered the requirement.
    Section
    39(a) of the Act allows the Agency 90 days to
    render its decision on any permit request.
    Therefore, any supplier that desires an
    A~encvdetermination pursuant to Sectioii
    611.354(e) (2) must submit the required
    infomation within the three month time-frame

    after Public Health determines that the
    groundwater is under the direct influence of
    surface water.
    d)
    The supplier shall collect samples at regular time
    intervals throughout the month,
    except that a supplier
    which uses only groundwater (except groundwater under
    the direct influence of surface water)
    and serves 4,900
    persons or fewer, may collect all required samples on a
    single day if they are taken from different sites.
    e)
    A PWS that uses surface water or groundwater under the
    direct influence of surface water, and does not
    practice filtration in compliance with Subpart
    Bgi
    this Part,
    shall collect at least one sample near the
    first service connection each day the turbidity level
    of the source water, measured as specified in Section
    611.532 (b), exceeds 1 NTU.
    This sample must be
    analyzed for the presence of total coliforins.
    When one
    or more turbidity measurements in any day exceed 1 NTU,
    the supplier shall collect this coliform sample within
    24 hours of the first exceedance, unless the Agency has
    determined,
    by special exception permit, that the
    supplier, for logistical reasons outside the supplier’s
    control, cannot have the sample analyzed within 30
    hours of collection.
    Sample results from this coliform
    monitoring must be included in determining compliance
    with the MCL for total coliforms in Section 611.325.

    turbidity frequency will be permitted only in
    those suppliers that practice disinfection and
    which maintain an active RDC in the distribution
    system, and in those cases where Public Health has
    indicated in writing that no unreasonable risk to
    health existed under the circumstances of this
    option.
    2)
    The turbidity measurements must be made in
    accordance with the following methods,
    incorporated by reference in Section 611.102:
    A)
    By the Nephelometric Method:
    i)
    Standard Methods:
    Method 214A;
    or
    ii)
    USEPA Inorganic Methods:
    Method 180.1.
    B)
    Calibration of the turbidimeter must be made
    either by the use of a formazin standard as
    specified in the cited references, or a
    styrene divinylbenzene polymer standard
    (Ainco-AEPA-1 Polymer).
    b)
    If the result of a turbidity analysis indicates that
    the maximum allowable limit has been exceeded, the
    sampling and measurement must be confirmed by
    resampling as soon as practicable and preferably within
    one hour.
    If the repeat sample confirms that the
    maximum allowable limit has been exceeded, the supplier
    of water shall report to the Agency within 48 hours.
    U

    114
    The repeat sample must be the sample used for the
    purpose of calculating the monthly average. If the
    monthly average of the daily samples exceeds the
    maximum allowable limit,
    or if the average of two
    samples taken on consecutive days exceeds 5 NTU, the
    supplier of water shall report to the Agency and notify
    the public as directed in Subpart T of this Part.
    c)
    Sampling for non-CWSs must begin by June 29,
    1991.
    d)
    This Section applies only to suppliers that use water
    obtained in whole or in part from surface sources.

    Analyses for the purpose of determining compliance with
    the old inorganic NCLs of Section 611.300 are required
    as follows:
    1)
    Analyses for all CWSs utilizing surface water
    sources must be repeated at yearly intervals.
    2)
    Analyses for all CWSs utilizing only groundwater
    sources must be repeated at three—year intervals.
    3)
    This subsection corresponds with 40 CFR
    141.23(1) (3)
    (199~),which requires monitoring
    for the repealed old MCL for nitrate at a
    frequency specified by the state.
    The Board has
    followed the USEPA lead and repealed that old MCL.

    rules.
    This statement maintains structural
    consistency with USEPA rules.
    b)
    If the result of an analysis made under subsection
    (a)
    above indicates that the level of any contaminant
    listed in Section 611.300 exceeds the old MCL, the
    supplier shall report to the Agency within
    7 days and
    initiate three additional analyses at the same sampling
    point within one month.
    C)
    When the average of four analyses made pursuant to
    subsection
    (b) above,
    rounded to the same number of
    significant figures as the old MCL for the substance in
    question, exceeds the old MCL, the supplier shall
    notify the Agency and give notice to the public
    pursuant to Subpart T of this Part.
    Monitoring after
    public notification must be at a frequency designated
    by the Agency by a SEP granted pursuant to Section
    611.110 and must continue until the old MCL has not
    been exceeded in two successive samples or until a
    different monitoring schedule becomes effective as a
    condition to a variance, an adjusted standard,
    a site
    specific rule, an enforcement action, or another SEP
    granted pursuant to Section 611.110.
    d)
    This subsection corresponds with 40 CFR 141.23(o)
    (199lZ), which pertains to monitoring for the repealed
    old MCL for nitrate.
    The Board has followed the USEPA
    action and repealed that old MCL.
    This statement
    maintains structural consistency with USEPA rules.
    e)
    This subsection corresponds with 40 CFR 141.23(p)
    (l99-~2),which pertains to the use of existing data up
    until a date long since expired.
    The Board did not
    adopt the original provision in R88—26.

    CWS suppliers shall collect and analyze one sample per
    plant at the entry point of the distribution system for
    L~2-O256

    127
    the determination of sodium concentration
    levels;
    samples must be collected and analyzed annually for
    CWS5 utilizing surface water sources in whole or in
    part, and at least every three years for CWSs utilizing
    solely groundwater sources. The minimum number of
    samples required to be taken by the supplier is based
    on the number of treatment plants used by the supplier,
    except that multiple wells drawing raw water from a
    single aquifer may, with the Agency approval, be
    considered one treatment plant for determining the
    minimum number of samples. The Agency shall require the
    supplier to collect and analyze water samples for
    sodium more frequently in locations where the sodium
    content is variable.
    b)
    The CWS supplier shall report to the Agency the results
    of the analyses for sodium within the first 10 days of
    the month following the month in which the sample
    results were received or within the first 10 days
    following the end of the required monitoring period as
    specified by SEP, whichever of these is first.
    If more
    than annual sampling is required the supplier shall
    report the average sodium concentration within
    10 days
    of the month following the month in which the
    analytical results of the last sample used for the
    annual average was received.
    C)
    The CWS supplier shall notify the Agency and
    appropriate local public health officials of the sodium
    levels by written notice by direct mail within three
    months. A copy of each notice required to be provided
    by this subsection must be sent to the Agency within
    10
    days of its issuance.
    d)
    Analyses for sodium must be performed by the following
    methods, incorporated by reference in Section 611.102:

    epoxide are also “Phase II SOC5”.
    The additional
    state requirements of Section 611.310 impose a
    more stringent “old MCL” for each of these
    compounds than that imposed on them as Phase
    II
    SOC5 by Section 611.311.
    However, the
    requirements for sampling and monitoring for these
    compounds as Phase II SOCs and the consequences of
    their detection and violation of their revised
    MCLs is more stringent as Phase II SOC5.

    Section 611.646
    Phase
    I and Phase II Volatile Organic
    Contaminants
    Monitoring of the Phase I VOCs and Phase II VOCs for the purpose
    of determining compliance with the MCL must be conducted as
    follows:
    a)
    Definitions.
    As used in this Section:
    “Detect” and “detection” means that the
    contaminant of interest is present at a level
    greater than or equal to the “detection limit”.
    “Detection limit” means 0.0005 mg/L.
    BOARD NOTE:
    Derived from 40 CFR 141.24(f) (7),
    (f)(11),
    (f)(14)(i), and
    (f)(20)
    (1994~2). This is
    a “trigger level” for Phase I VOC5 and Phase II
    VOCs inasmuch as it prompts further action.
    The
    use of the term “detect” in this section is not
    intended to include any analytical capability of
    quantifying lower levels of any contaminant, or
    the “method detection limit”.
    Note, however that
    certain language at the end of federal paragraph
    (f) (20)
    is capable of meaning that the “method
    detection limit” is used to derive the “detection
    limit”.
    The Board has chosen to disregard that
    language at the end of paragraph
    (f) (20)
    in favor
    of the more direct language of paragraphs
    (f) (7)
    and
    (f) (11).
    “Method detection limit”, as used in subsections
    (q) and
    (t) below means the minimum concentration
    of a substance that can be measured and reported
    with 99 percent confidence that the analyte
    concentration is greater than zero and is
    determined from analysis of a sample in a given
    matrix containing the analyte.
    01 L~2-0260

    131
    BOARD NOTE:
    Derived from 40 CFR 136, Appendix B
    (l994~). The method detection limit is determined
    by the procedure set forth in 40 CFR 136, Appendix
    B.
    See subsection
    (t)
    below.
    b)
    Required sampling.
    Each supplier shall take a minimum
    of one sample at each sampling point at the times
    required in subsection
    (u)
    below.
    C)
    Sampling points.
    1)
    Sampling points for GWSs.
    Unless otherwise
    provided by SEP,
    a GWS supplier shall take at
    least one sample from each of the following
    points:
    each entry point that is representative
    of each well after treatment.
    2)
    Sampling points for SWSs and mixed systems.
    Unless otherwise provided by SEP,
    a SWS or mixed
    system supplier shall sample from each of the
    following points:
    A)
    Each entry point after treatment; or
    B)
    Points in the distribution system that are
    representative of each source.
    3)
    The supplier shall take each sample at the same
    sampling point unless the Agency has granted a SEP
    that designates another location as more
    representative of each source, treatment plant,
    or
    within the distribution system.
    4)
    If a system draws water from more than one source,
    and the sources are combined before distribution,
    the supplier shall sample at an entry point during
    periods of normal operating conditions when water
    is representative of all sources being used.
    BOARD NOTE:
    Subsections
    (b) and
    (c)
    above derived
    from 40 CFR 141.24(f) (1) through
    (f)(3) (199~).
    d)
    Each CWS and NTNCWS supplier shall take four
    consecutive quarterly samples for each of the Phase I
    VOCs,
    excluding vinyl chloride, and Phase II VOCs
    during each compliance period, beginning in the
    compliance period starting January
    1,
    1993.
    e)
    Reduction to annual monitoring frequency.
    If the
    initial monitoring for the Phase I VOC5 and Phase II
    VOCs as allowed in subsection
    (r) (1) below has been
    completed by December 31,
    1992, and the supplier did
    U

    132
    not detect any of the Phase
    I VOCs,
    including vinyl
    chloride,
    or Phase II VOCs, then the supplier shall
    take one sample annually beginning January 1,
    1993.
    f)
    GWS reduction to triennial monitoring frequency.
    After
    a minimum of three years of annual sampling, GWS
    suppliers that have not previously detected any of the
    Phase I VOC5,
    including vinyl chloride, or Phase II
    VOCs shall take one sample during each three—year
    compliance period.
    g)
    A CWS or NTNCWS supplier that has completed the initial
    round of monitoring required by subsection
    (d) above
    and which did not.detect any of the Phase I VOCs,
    including vinyl chloride, and Phase II VOCs may apply
    to the Agency for a SEP pursuant to Section 611.110
    that releases it
    from
    the requirements of subsection
    (e) or
    (f)
    above.
    BOARD
    NOTE:
    Derived from 40 CFR 141.24(f) (7)
    and
    (f) (10) (199~).
    Provisions concerning the term of the
    waiver appear below in subsections
    (i) and
    (j)
    below.
    The definition of “detect”, parenthetically added to
    the federal counterpart paragraph is in subsection
    (a)
    above.
    h)
    Vulnerability Assessment.
    The Agency shall consider
    the factors of Section 611.110(e)
    in granting a SEP
    from the requirements of subsections
    (e)
    or
    (f) above
    sought pursuant to subsection
    (g)
    above.
    i)
    A SEP issued to a GWS pursuant to subsection
    (g)
    above
    is for a maximum of six years.
    As a condition of a
    SEP, the supplier shall, within 30 months after the
    beginning of the period for which the waiver was
    issued, reconfirm its vulnerability assessment required
    by subsection
    (h) above and submitted pursuant to
    subsection
    (g)
    above,
    by taking one sample at each
    sampling point and reapplying for a SEP pursuant to
    subsection
    (g)
    above.
    Based on this application, the
    Agency shall either:
    1)
    If it determines that the PWS meets the standard
    of Section 611.610(e),
    issue a SEP that reconfirms
    the prior SEP for the remaining three-year
    compliance period of the six—year maximum term;
    or,
    2)
    Issue a new SEP requiring the supplier to sample
    annually.
    BOARD NOTE:
    This provision does not apply to SWSs
    0
    1L~2-0262

    133
    and mixed systems.
    j)
    Special considerations for SEPs for SWS and mixed
    systems.
    1)
    The Agency must determine that a SWS is not
    vulnerable before issuing a SEP pursuant to a SWS
    supplier.
    A SEP issued to a SWS or mixed system
    supplier pursuant to subsection
    (g)
    above is for a
    maximum of one compliance period; and
    2)
    The Agency may require, as a condition to a SEP
    issued to a SWS or mixed supplier, that the
    supplier take such samples for Phase
    I VOC5 and
    Phase II VOCs at such a frequency as the Agency
    determines are necessary, based on the
    vulnerability assessment.
    BOARD NOTE:
    There is a great degree of similarity
    between 40 CFR 141.24(f) (7), the provision
    applicable to GWSs,
    and 40 CFR 141.24(f) (10),
    the
    provision for SWSS.
    The Board has consolidated
    the common requirements of both paragraphs into
    subsection
    (g)
    above.
    Subsection
    (j)
    above
    represents the elements unique to SWSs and mixed
    systems, and subsection
    (1)
    above relates to GWSs.
    Although 40 CFR 141.24(f) (7) and
    (f) (10)
    are
    silent as to mixed systems, the Board has included
    mixed systems with SWSs because this best follows
    the federal scheme for all other contaminants.
    k)
    If one of the Phase I VOCs,
    excluding vinyl chloride,
    or Phase II VOCs is detected in any sample, then:
    1)
    The supplier shall monitor quarterly for that
    contaminant at each sampling point that resulted
    in a detection.
    2)
    Annual monitoring.
    A)
    The Agency shall grant a SEP pursuant to
    Section 611.110 that allows a supplier to
    reduce the monitoring frequency to annual at
    a sampling point if it determines that the
    sampling point is reliably and consistently
    below the I4CL.
    B)
    A request for a SEP must include the
    following minimal information:
    i)
    For a GWS, two quarterly samples.
    01
    L~2-0263

    134
    ii)
    For a SWS or mixed system, four
    quarterly samples.
    C)
    In issuing
    a SEP, the Agency shall specify
    the level of the contaminant upon which the
    “reliably and consistently” determination was
    based.
    All SEPS that allow less frequent
    monitoring based on an Agency “reliably and
    consi~tently”determination shall include a
    condition requiring the supplier to resume
    quarterly monitoring pursuant to subsection
    (k) (1)
    above if it violates the MCL specified
    by Section 611.311.
    3)
    Suppliers that monitor annually shall monitor
    during the quarter(s)
    that previously yielded the
    highest analytical result.
    4)
    Suppliers that do not detect a contaminant at a
    sampling point in three consecutive annual samples
    may apply to the Agency for a SEP pursuant to
    Section 611.110 that allows it to discontinue
    monitoring for that contaminant at that point, as
    specified in subsection
    (g)
    above.
    5)
    A GWS supplier that has detected one or more of
    the two—carbon contaminants listed in subsection
    (k) (5) (A) below shall monitor quarterly for vinyl
    chloride as described in subsection
    (k) (5) (B)
    below, subject to the limitation of subsection
    (k) (5) (C)
    below.
    A)
    Two-carbon contaminants
    (Phase I or II VOC):
    1,2-Dichloroethane (Phase I)
    1,1-Dichloroethylene
    (Phase
    I)
    cis-l,2-Dichloroethylene
    (Phase II)
    trans-i,2-Dichloroethylene
    (Phase II)
    Tetrachloroethylene
    (Phase II)
    1,1,1-Trichloroethylene (Phase I)
    Trichloroethylene
    (Phase
    I)
    B)
    The supplier shall sample quarterly for vinyl
    chloride at each sampling point at which it
    detected one or more of the two-carbon
    contaminants listed in subsection
    (k) (5) (A)
    above.
    C)
    The Agency shall grant a SEP pursuant to
    Section 611.110 that allows the supplier to
    reduce the monitoring frequency for vinyl
    chloride at any sampling point to once in
    3
    L:~2-i)26Lt

    135
    each three-year compliance period if it
    determines that the supplier has not detected
    vinyl chloride in first sample required by
    subsection
    (k) (5) (B)
    above.
    1)
    Quarterly monitoring following MCL violations.
    1)
    Suppliers that violate an NCL for one of the Phase
    I VOCs,
    including vinyl chloride, or Phase II
    VOCs, as determined by subsection
    (0)
    below,
    shall
    monitor quarterly for that contaminant, at the
    sampling point where the violation occurred,
    beginning the next quarter after the violation.
    2)
    Annual
    monitoring.
    A)
    The Agency shall grant a SEP pursuant to
    Section 611.110 that allows a supplier to
    reduce the monitoring frequency to annually
    if it determines that the sampling point is
    reliably and consistently below the MCL.
    B)
    A request for a SEP must include the
    following minimal information:
    four
    quarterly samples.
    C)
    In issuing a SEP, the Agency shall specify
    the level of the contaminant upon which the
    “reliably and consistently” determination was
    based.
    All SEPs that allow less frequent
    monitoring based on an Agency “reliably and
    consi~.tently”determination shall include a
    condition requiring the supplier to resume
    quarterly monitoring pursuant to subsection
    (1) (1)
    above if it violates the MCL specified
    by Section 611.311.
    D)
    The supplier shall monitor during the
    quarter(s) that previously yielded the
    highest analytical result.
    m)
    Confirmation samples.
    The Agency may issue a SEP
    pursuant to Section 610.110 to require a supplier to
    use a confirmation sample for results that it finds
    dubious for whatever reason.
    The Agency must state its
    reasons for issuing the SEP if the SEP is Agency—
    initiated.
    1)
    If a supplier detects any of the Phase
    I VOCs or
    Phase II VOCs in a sample, the supplier shall take
    a confirmation sample as soon as possible, but no
    later than 14 days after the supplier receives
    01
    ~2-U265

    136
    notice of the detection.
    2)
    Averaging is as specified in subsection
    (0)
    below.
    3)
    The Agency shall delete the original or
    confirmation sample if it determines that a
    sampling error occurred,
    in which case the
    confirmation sample will replace the original or
    confirmation sample.
    n)
    This subsection corresponds with 40 CFR 141.24(f) (14),
    an optional USEPA provision relating to compositing of
    samples that USEPA does not require for state programs.
    This statement maintains structural consistency with
    USEPA rules.
    o)
    Compliance with the MCLs for the Phase
    I VOCs and Phase
    II VOC5 must be determined based on the analytical
    results obtained at each sampling point.
    1)
    For suppliers that conduct monitoring at a
    frequency greater than annual, compliance is
    determined by a running annual average of all
    samples taken at each sampling point.
    A)
    If the annual average of any sampling point
    is greater than the MCL, then the supplier is
    out of compliance.
    B)
    If the initial sample or a subsequent sample
    would cause the annual average to exceed the
    MCL, then the supplier is out of compliance
    immediately.
    C)
    Any samples below the detection limit shall
    be deemed as zero for purposes of determining
    the annual average.
    2)
    If monitoring is conducted annually, or less
    frequently, the supplier is out of compliance if
    the level of a contaminant at any sampling point
    is greater than the MCL.
    If
    a confirmation sample
    is taken,
    the determination of compliance is based
    on the average of two samples.
    3)
    Public notice for a supplier out of compliance is
    governed by Subpart P of this Part.
    p)
    Analyses for the Phase I VOCs and Phase II VOC5 must be
    conducted using the following methods.
    These methods
    are contained in USEPA Organic Methods,
    incorporated by
    reference in Section 611.102:

    Section 611.647
    Sampling for Phase
    I Volatile Organic
    Contaminants
    For systems in operation before January
    1,
    1993, for purposes of
    initial monitoring, analysis of Phase I VOCs for purposes of
    determining compliance with the MCL5 must be conducted as
    follows:
    a)
    GWS suppliers shall sample at entry points
    representative of each well after treatment.
    Sampling
    must be conducted at the same location(s)
    or more
    representative location(s)
    every three months for one
    year except as provided in subsection
    (h) (1)
    below.
    b)
    SWS and mixed system suppliers using surface sources
    shall sample at points in the distribution system
    representative of each source or at entry points to the
    distribution system after any application of treatment.
    SWS5 and mixed system suppliers shall sample each
    source every three months except as provided in
    subsection
    (h) (2)
    below.
    Sampling must be conducted at
    the same location or a more representative location
    each quarter.
    c)
    If the system draws water from more than one source and
    sources are combined before distribution, the supplier
    shall sample at an entry point to the distribution
    system during periods of normal operating conditions.
    d)
    Time for sampling.
    1)
    All CWS and NTNCWS suppliers serving more than
    L~2-(J
    269

    140
    3,300 people shall analyze all distribution or
    entry—point samples, as appropriate,
    representing
    all source waters.
    2)
    All other CWS and NTNCWS suppliers shall analyze
    distribution or entry—point samples, as required
    in this paragraph,
    representing all source waters
    beginning no later than January
    1,
    1991.
    e)
    If the results exceed the NCL, the CWS or NTNCWS
    supplier shall initiate three additional analyses at
    the same sampling point within one month.
    The sample
    results must be averaged with the first sampling result
    and used for compliance determination in accordance
    with subsection
    (i)
    below.
    The Agency shall delete
    results of obvious sampling errors from this
    calculation.
    f)
    Analysis for vinyl chloride is required only for GWSs
    that have detected one or more of the following two—
    carbon organic compounds: Trichloroethylene,
    tetrachloroethylene,
    l,2-dichloroethane,
    1,1,1—
    trichloroethane,
    cis—l,2-dichloroethylene, trans—i,2—
    dichloroethylene or 1,1-dichioroethylene.
    The analysis
    for vinyl chloride is required at each distribution or
    entry point at which one or more of the two—carbon
    organic compounds were found.
    If the first analysis
    does not detect vinyl chloride, the Agency shall reduce
    the frequency of vinyl chloride monitoring to once
    every three years for that sample location or other
    sample locations that are more representative of the
    same source.
    g)
    The Agency or suppliers may composite up to five
    samples from one or more suppliers.
    Compositing of
    samples is to be done in the laboratory by the
    procedures listed below.
    Samples must be analyzed
    within fourteen days of collection.
    If any of the
    Phase
    I VOCs is detected in the original composite
    sample,
    a sample from each source that made up the
    composite sample must be reanalyzed individually within
    fourteen days from sampling.
    The sample for reanalysis
    cannot be the original sample but can be a duplicate
    sample.
    If duplicates of the original samples are not
    available, new samples must be taken from each source
    used in the original composite and analyzed for the
    Phase
    I
    VOCs.
    Reanalysis must be accomplished within
    fourteen days of the second sample.
    To composite
    samples, the following procedure must be followed:
    1)
    Compositing samples prior to GC analysis.
    0~
    L~2-~J270

    141
    A)
    Add
    5 ml or equal larger amounts of each
    sample
    (up to 5 samples are allowed) to a 25
    ml glass syringe.
    Special precautions must
    be made to maintain zero headspace in the
    syringe.
    B)
    The samples must be cooled at
    40
    C during
    this step to minimize volatilization losses.
    C)
    Mix well and draw out a 5-mi aliquot for
    analysis.
    D)
    Follow sample introduction, purging and
    desorption steps described in the method.
    E)
    If less than five samples are used for
    compositing,
    a proportionately smaller
    syringe may be used.
    2)
    Compositing samples prior to GC/MS analysis.
    A)
    Inject 5—ml or equal larger amounts of each
    aqueous sample
    (up to
    5 samples are allowed)
    into a 25-mi purging device using the sample
    introduction technique described in the
    method.
    B)
    The total volume of the sample in the purging
    device must be 25 ml.

    611.650(c),
    611.657(d)
    or 611.311(a), except for
    TIiIfs
    or other demonstrated disinfection by-
    products.
    This subsection corresponds with 40 CFR 141.24(g) (8)
    the effectiveness of which extired on January
    1,
    1993.
    Although USEPA has not repealed this provision,
    the
    Board has done so to avoid confusion.
    This statement
    maintains structural integrity with USEPA rules.
    i)
    Compliance with Section 611.311(a)
    is determined based
    on the results of running annual average of quarterly
    sampling for each sampling location.
    If one location’s
    average is greater than the MCL, then the CWS or NTNCWS
    is deemed to be out of compliance.
    If a CWS or NTNCWS
    has a distribution system separable from other parts of
    the distribution system with no interconnections, only
    that part of the system that exceeds any MCL as
    specified in Section 611.311(a)
    is deemed out of
    compliance.
    The Agency shall, by SEP, reduce the
    public notice requirement to that portion of the CWS
    that is out of compliance.
    If any one sample result
    would cause the annual average to be exceeded, then the
    CWS is deemed to be out of compliance immediately.
    For
    CWS suppliers that only take one sample per location
    because none of the Phase
    I VOCs were detected,
    compliance is based on that one sample.

    Section 611.648
    Phase II Synthetic Organic Contaminants
    Analysis of the Phase II SOC5 for the purposes of determining
    compliance with the MCL must be conducted as follows:
    a)
    Definitions.
    As used in this Section:
    “Detect or detection” means that the contaminant
    of interest is present at a level greater than or
    equal to the “detection limit”.

    146
    “Detection limit” means the level of the
    contaminant of interest that is specified in
    subsection
    (r) below.
    BOARD
    NOTE:
    This is a “trigger level” for Phase
    II SOCs inasmuch as it prompts further action.
    The use of the term “detect” or “detection”
    in
    this section is not intended to include any
    analytical capability of quantifying lower levels
    of any contaminant, or the “method detection
    limit”.
    b)
    Required sampling.
    Each supplier shall take a minimum
    of one sample at each sampling point at the times
    required in subsection
    (q)
    below.
    BOARD
    NOTE:
    USEPA staved the effective date of the
    MCLs for aldicarb. aldicarb sulfone, and aldicarb
    sulfoxide at 57 Fed.
    Reg.
    22178
    (May 27,
    1991).
    Section 611.311(c)
    includes this stay.
    However,
    despite the stay of the effectiveness of the MCLs for
    these three SOC5.
    suppliers must monitor for them.
    c)
    Sampling points.
    1)
    Sampling points for GWSs.
    Unless otherwise
    provided by SEP,
    a GWS supplier -shall take at
    least one sample from each of the following
    points:
    each entry point that is representative
    of each well after treatment.
    2)
    Sampling points for SWSs and mixed systems.
    Unless otherwise provided by SEP, a SWS or mixed
    system supplier shall sample from each of the
    following points:
    A)
    Each entry point after treatment;
    or
    B)
    Points in the distribution system that are
    representative of each source.
    3)
    The supplier shall take each sample at the same
    sampling point unless the Agency has granted a SEP
    that designates another location as more
    representative of each source, treatment plant,
    or
    within the distribution system.
    4)
    If a system draws water from more than one source,
    and the sources are combined before distribution,
    the supplier shall sample at an entry point during
    periods of normal operating conditions when water
    is representative of all sources being used.

    (h) (3)
    (1994~a).
    d)
    Monitoring frequency:
    1)
    Each CWS and NTNCWS supplier shall take four
    consecutive quarterly samples for each of the
    Phase II SOCs during each compliance period,
    beginning in the three-year compliance period
    starting January 1,
    1993.
    2)
    Suppliers serving more than 3,300 persons that do
    not detect a contaminant in the initial compliance
    period,
    shall take a minimum of two quarterly
    samples in one year of each subsequent three—year
    compliance period.
    3)
    Suppliers serving less than or equal to 3,300
    persons that do not detect a contaminant in the
    initial compliance period,
    shall take a minimum of
    one sample during each subsequent three—year
    compliance period.
    e)
    Reduction to annual monitoring frequency.
    A CWS or
    NTNCWS supplier may apply to the Agency for a SEP that
    releases it from the requirements of subsection
    (d)
    above.
    A SEP from the requirement of subsection
    (d)
    above shall last for only a single three—year
    compliance period.
    f)
    Vulnerability Assessment.
    The Agency shall grant a SEP
    from the requirements of subsection
    (d)
    above based on
    consideration of the factors set forth at Section
    611.110(e).
    g)
    If one of the Phase II SOC5 is detected in any sample,
    then:
    1)
    The supplier shall monitor quarterly for the
    contaminant at each sampling point that resulted
    in a detection.
    2)
    Annual monitoring.
    A)
    A supplier may request that the Agency grant
    a SEP pursuant to Section 610.110 that
    reduces the monitoring frequency to annual.
    B)
    A request for a SEP must include the
    following minimal information:
    i)
    For a GWS, two quarterly samples.
    0iL~2

    148
    ii)
    For a SWS or mixed system, four
    quarterly samples.
    C)
    The Agency shall grant a SEP that allows
    annual monitoring at a sampling point if it
    determines that the sampling point is
    reliably and consistently below the MeL.
    D)
    In issuing the SEP, the Agency shall specify
    the level of the contaminant upon which the
    “reliably and consistently” determination was
    based
    All SEPs that allow less frequent
    monitoring based on an Agency “reliably and
    consi~tently”determination shall include a
    condition requiring the supplier to resume
    quarterly monitoring pursuant to subsection
    -
    (g) (1)
    above if it detects any Phase II SOC.
    3)
    Suppliers that monitor annually shall monitor
    during the quarter(s) that previously yielded the
    highest analytical result.
    4)
    Suppliers that have three consecutive annual
    samples with no detection of a contaminant at a
    sampling point may apply to the Agency for a SEP
    with respect to that point,
    as specified in
    subsections
    (e) and
    (f)
    above.
    5)
    1~1onitoringfor related contaminants.
    A)
    If monitoring results in detection of one or
    more of the related contaminants listed in
    subsection
    (g) (5) (8)
    below, subsequent
    monitoring shall analyze for all the related
    compounds in the respective group.
    B)
    Related contaminants:

    Quarterly monitoring following MCL violations.
    1)
    Suppliers that violate an MCL for one of the Phase
    U
    L~2-0278

    149
    II SOCs, as determined by subsection
    (k)
    below,
    shall monitor quarterly for that contaminant at
    the sampling point where the violation occurred,
    beginning the next quarter after the violation.
    2)
    Annual monitoring.
    A)
    A supplier may request that the Agency grant
    a SEP pursuant to Section 611.110 that
    reduces the monitoring frequency to annual.
    B)
    A request for a SEP must include, at a
    minimum, the results from four quarterly
    samples.
    C)
    The Agency shall grant a SEP that allows
    annual monitoring at a sampling point if it
    determines that the sampling point is
    reliably and consistently below the MCL.
    D)
    In issuing the SEP, the Agency shall specify
    the level of the contaminant upon which the
    “reliably and consistently” determination was
    based
    All SEPS that allow less frequent
    monitoring based on an Agency “reliably and
    consi~tently”determination shall include a
    condition requiring the supplier to resume
    quarterly monitoring pursuant to subsection
    (h) (1)
    above
    if it detects any Phase II SOC.
    E)
    The supplier shall monitor during the
    quarter(s) that previously yielded the
    highest analytical result.
    i)
    Confirmation samples.
    1)
    If any of the Phase II SOC5 are detected in a
    sample, the supplier shall take a confirmation
    sample as soon as possible, but no later than 14
    days after the supplier receives notice of the
    detection.
    2)
    Averaging is as specified in subsection
    (k)
    below.
    3)
    The Agency shall delete the original or
    confirmation sample if it determines that a
    sampling error occurred,
    in which case the
    confirmation sample will replace the original or
    confirmation sample.
    j)
    This subsection corresponds with 40 CFR 141.24(h) (10),

    samples that tJSEPA does not require for state programs.
    This statement maintains structural consistency with
    USEPA rules.
    k)
    Compliance with the MCLs for the Phase II SOCs shall be
    determined based on the analytical results obtained at
    each sampling point.
    1)
    For suppliers that are conducting monitoring at a
    frequency greater than annual, compliance is
    determined by a running annual average of all
    samples taken at each sampling point.
    A)
    If the annual average of any sampling point
    is greater than the MCL, then the supplier is
    out of compliance.
    B)
    If the initial sample or a subsequent sample
    would cause the annual average to be
    exceeded, then the supplier is out of
    compliance immediately.
    C)
    Any samples below the detection limit must be
    calculated as zero for purposes of
    determining the annual average.
    2)
    If monitoring is conducted annually or less
    frequently, the supplier is out of compliance if
    the level of a contaminant at any sampling point
    is greater than the MCL.
    If a confirmation sample
    is taken,
    the determination of compliance is based
    on the average of two samples.
    3)
    Public notice for a supplier out of compliance is
    governed by Subpart T of this Part.

    Trichloroethylene.
    The United States Environmental
    Protection Agency
    (USEPA) sets drinking water standards
    and has determined that trichloroethylene is
    a health
    concern at certain levels of exposure.
    This chemical
    is a common metal cleaning and dry cleaning- fluid.
    It
    generally gets into drinking water by improper waste
    disposal.
    This chemical has been shown to cause cancer
    in laboratory animals- such as rats and mice when the
    animals are exposed at high levels over their
    lifetimes.
    Chemicals that cause cancer in laboratory
    animals also may increase the risk of cancer in humans
    who are exposed at lower levels over long periods of
    U~:.2-028L~.

    155
    time.
    USEPA has set forth the enforceable drinking
    water standard for trichloroethylene at 0.005 parts per
    million
    (ppm)
    to reduce the risk of cancer or other
    adverse health effects which have been observed in
    laboratory animals.
    Drinking water which meets this
    standard is associated with little to none of this risk
    and should be considered safe.

    and has determined that carbon tetrachioride is a
    health concern at certain levels of exposure.
    This
    chemical was once a popular household cleaning fluid.
    It generally gets into drinking water by improper waste
    disposal.
    This chemical has been shown to cause cancer
    in laboratory animals such as rats and mice when the
    animals are exposed at high levels over their
    lifetimes.
    Chemicals that cause cancer in laboratory
    animals also may increase the risk of cancer in humans
    who are exposed at lower levels over long periods of
    time.
    USEPA has set the enforceable drinking water
    standard for carbon tetrachioride at 0.005 parts per
    million
    (ppm)
    to reduce the risk of cancer or other
    adverse health effects which have been observed in
    laboratory animals.
    Drinking water which meets this
    standard is associated with little to none of this risk
    and should be considered safe.
    3)
    1,2-Dichloroethane.
    The United States Environmental
    Protection Agency (USEPA) sets drinking water standards
    and has determined that 1,2-dichioroethane is a health
    concern at certain levels of exposure.
    This chemical
    is used as a cleaning fluid for fats,
    oils, waxes and
    resins.
    It generally gets into drinking water by
    improper waste disposal.
    This chemical has been shown
    to cause cancer in laboratory animals such as rats and

    and has determined that vinyl chloride is a health
    concern at certain levels of exposure.
    This chemical
    O~2-O265

    156
    is used in industry and is found in drinking water as a
    result of the breakdown of related solvents.
    The
    solvents are used as cleaners and degreasers of metals
    and generally get into drinking water by improper waste
    disposal.
    This chemical has been associated with
    ~iqnificant1y increased risks of cancer among certain
    ‘—ial workers who were exposed to relatively large
    amou.._ of this chemical during their working careers.
    This chemical has also been shown to cause cancer in
    laboratory animals when the animals are exposed at high
    levels over their lifetimes.
    Chemicals that cause

    workers and in laboratory animals also may increase the
    risk of cancer in humans who are exposed at lower
    levels over long periods of time.
    USEPA has set the
    enforceable drinking water standard for vinyl chloride
    at 0.002 parts per million
    (ppm)
    to reduce the risk of
    cancer or other adverse health effects which have been
    observed in laboratory animals.
    Drinking water which
    meets this standard is associated with little to none
    of this risk and should be considered safe.
    5)
    Benzene.
    The United States Environmental Protection
    Agency
    (USEPA)
    sets drinking water standards and has
    determined that benzene is a health concern at certain
    levels of exposure.
    This chemical is used as a solvent
    and degreaser of metals.
    It is also a major component
    of gasoline.
    Drinking water contamination generally
    results from leaking underground gasoline and petroleum
    tanks or improper waste disposal.
    This chemical has
    been associated with significantly increased risks of
    leukemia among certain industrial workers who were
    exposed to relatively large amounts of this chemical
    during their working careers.
    This chemical has also
    been shown to This chemical has been shown to cause

    7)
    Para—dichlorobenzene.
    The United States Environmental
    Protection Agency (USEPA) sets drinking water standards
    and has determined that para—dichlorobenzene is a
    health concern at certain levels of exposure.
    This
    chemical is a component of deodorizers, moth balls and
    pesticides.
    It generally gets into drinking water by
    improper waste disposal.
    This chemical has been shown
    to cause liver and kidney damage in laboratory animals
    such as rats and mice when the animals are exposed at
    high levels over their lifetimes.
    Chemicals which
    cause adverse effects in laboratory animals also may
    cause adverse health effects in humans who are exposed
    at lower levels over long periods of time.
    USEPA has
    set the enforceable drinking water standard for para—
    dichlorobenzene at 0.075 parts per million
    (ppm)
    to
    reduce the risk of these adverse health effects which
    have been observed in laboratory animals.
    Drinking
    water which meets this standard is associated with
    little to none of this risk and should be considered
    safe.
    8)
    1,l,1-Trichloroethane.
    The United States Environmental
    Protection Agency (USEPA)
    sets drinking water standards
    and has determined that 1,1,1-trichioroethane is a
    health concern at certain levels of exposure.
    This
    chemical is used as a cleaner and degreaser of metals.
    It generally gets into drinking water by improper waste
    disposal.
    This chemical has been shown to damage the
    liver,
    nervous system and circulatory system of
    laboratory animals such as rats and mice when the
    animals are exposed at high levels over their
    lifetimes.
    Some industrial workers who were exposed to
    0~
    L~2-02B7

    158
    relatively large amounts of this chemical during their
    working careers also suffered damage to the liver,
    nervous system and circulatory system.
    Chemicals which
    cause adverse effects among exposed industrial workers
    and in laboratory animals also may cause adverse health
    effects in humans who are exposed at lower levels over
    long periods of time.
    USEPA has set the enforceable
    drinking water standard for 1,1,1—trichloroethane at
    0.2 parts per million
    (ppm)
    to protect against the risk
    of these adverse health effects which have been
    observed in laboratory -animals.
    Drinking water which
    meets this standard is associated with little to none
    of this risk and should be considered safe.
    9)
    Fluoride.
    The U.S. Environmental Protection Agency
    requires that we send you this notice on the level of
    fluoride in your drinking water.
    The drinking water in
    your community has a fluoride concentration of
    milligrams per liter
    (mgfL).
    Federal regulations require that fluoride, which occurs
    naturally in your water supply, not exceed a
    concentration of 4.0 mg/L in drinking water.
    This is
    an enforceable standard called a Maximum Contaminant
    Level
    (MCL), and it has been established to protect the
    public health.
    Exposure to drinking water levels above
    4.0 mg/L for many years may result in some cases of
    crippling skeletal fluorosis,
    which is a serious bone
    disorder.
    Federal law also requires that we notify you when
    monitoring indicates that the fluoride in your drinking
    water exceeds 2.0 mg/L.
    This is intended to alert
    families about dental problems that might affect
    children under nine years of age.
    The fluoride
    concentration of your water exceeds this federal
    guideline.
    Fluoride in children’s drinking water at levels of
    approximately
    1 mg/L reduces the number of dental
    cavities.
    However, some children exposed to levels of
    fluoride greater than about 2.0 mg/L may develop dental
    fluorosis.
    Dental fluorosis,
    in its moderate and
    severe forms,
    is a brown staining and/or pitting of the
    permanent teeth.
    Because dental fluorosis occurs only when developing
    teeth (before they erupt from the gums)
    are exposed to
    elevated fluoride levels, households without children
    are not expected to be affected by this level of
    fluoride.
    Families with children under the age of nine
    are encouraged to seek other sources of drinking water
    ~flL~2-02E-
    8

    159
    for their children to avoid the possibility of staining
    and pitting.
    Your water supplier can lower the concentration of
    fluoride in your water so that you will still receive
    the benefits of cavity prevention while the possibility
    of stained and pitted teeth is minimized.
    Removal of
    fluoride may increase your water costs.
    Treatment
    systems are also commercially available for home use.
    Information on such systems is available at the address
    given below.
    Low fluoride bottled drinking water that
    would meet all standards is also commercially
    available.
    For further information, contact
    at your
    water system.
    BOARD NOTE:

    Microbiological contaminants
    (for use when there is a
    violation of the treatment technique requirements for
    filtration and disinfection in Subpart B of this Part).
    The United States Environmental Protection Agency
    (USEPA)
    sets drinking water standards and has
    determined that the presence of microbiological
    contaminants are a health concern at certain levels of
    exposure.
    If water is inadequately treated,
    microbiological contaminants in that water may cause
    disease.
    Disease symptoms may include diarrhea,
    cramps, nausea and possibly jaundice and any associated
    headaches and fatigue.
    These symptoms, however, are
    not just associated with disease—causing organisms in
    drinking water,
    but also may be caused by a number of
    factors other than your drinking water.
    USEPA has set
    enforceable requirements for treating drinking water to
    reduce the risk of these adverse health effects.
    Treatment such as filtering and disinfecting the water
    removes or destroys microbiological contaminants.
    Drinking water which is treated to meet USEPA
    requirements is associated with little to none of this
    risk and should be considered safe.
    11)
    Total coliforms.
    (To be used when there is a violation
    of Section 611.325(a)
    and not a violation of Section
    611.325(b)).
    The United States Environmental
    Protection Agency
    (USEPA)
    sets drinking water standards
    and has determined that the presence of total coliforms
    is a possible health concern.
    Total coliforms are
    common in the environment and are generally not harmful
    themselves.
    The presence of these bacteria in drinking
    water, however, generally is
    a result of
    a problem with
    O~L~.2-O269

    160
    water treatment or the pipes which distribute the water
    and indicates that the water may be contaminated with
    organisms that can cause disease.
    Disease symptoms may
    include diarrhea, cramps, nausea and possibly jaundice,
    and any associated headaches and fatigue.
    These
    symptoms, however, are not just associated with
    disease—causing organisms in drinking water, but also
    may be caused by a number of factors other than your
    drinking water.
    USEPA has set an enforceable drinking
    water standard for total coliforms to reduce the risk
    of these adverse health effects.
    Under this standard,
    no more than 5.0 percent of the samples collected
    during a month can contain these bacteria, except that
    systems collecting fewer than 40 samples/month that
    have one total coliform—positive sample per month are
    not violating the standard.
    Drinking water which meets
    this standard is usually not associated with a health
    risk from disease—causing bacteria and should be
    considered safe.
    12)
    Fecal Coliforms/E.
    coli.
    (To be used when there is a
    violation of Section 611.325(b)
    or both Section
    611.325(a)
    and
    (b)).
    The United States Environmental
    Protection Agency
    (USEPA) sets drinking water standards
    and has determined that the presence of fecal coliforms
    or E. coli is a serious health concern.
    Fecal
    coliforms and E. coil are generally not harmful
    themselves, but their presence in drinking water is
    serious because they usually-are associated with sewage
    or animal wastes.
    The presence of these bacteria in
    drinking water is generally a result of a problem with
    water treatment or the pipes which distribute the water
    and indicates that the water may be contaminated with
    organisms that can cause disease.
    Disease symptoms may
    include diarrhea, cramps, nausea and possibly jaundice,
    and associated headaches and fatigue.
    These symptoms,
    however,
    are not just associated with disease—causing
    organisms in drinking water, but also may be caused by
    a number of factors other than your drinking water.
    USEPA has set an enforceable drinking water standard
    for fecal coliforins and E. coil to reduce the risk of
    these adverse health effects.
    Under this standard all
    drinking water samples must be free of these bacteria.
    Drinking water which meets this standard is associated
    with little or none of this risk and should be
    considered safe.
    State and local health authorities
    recommend that consumers take the following
    precautions:

    The United States
    Environmental Protection Agency
    (USEPA)
    sets drinking
    water standards and has determined that lead is
    a
    health concern at certain exposure levels.
    Materials
    that contain lead have freciuently been used in the
    construction
    of
    water
    supply
    distribution
    systems.
    and
    plumbing systems in private homes and other buildings.
    The_most commonly found materials include service
    lines, pipes.
    brass and bronze fixtures, and solders
    and fluxes.
    Lead in these materials can contaminate
    drinking water as a result of the corrosion that takes
    place when water comes into contact with those
    materials.
    Lead can cause a variety of adverse health
    effects in humans.
    At relatively low levels of
    exPosure,
    these effects may include interference with
    red blood cell chemistry,
    delays in normal physical and
    mental development in babies and young children, slight
    deficits in the attention span. hearing,
    and learning
    abilities of children, and slight increases in the
    blood pressure of some adults.
    USEPA’s national
    irimarv drinking water regulation requires all public
    water systems to optimize corrosion control to minimize
    lead contamination resulting from the corrosion of
    plumbing materials.
    Public water systems serving
    50~000people or fewer that have lead concentrations
    below 15 parts per billion (p~b) in more than 90
    of
    taP water samples (the USEPA “action level”) have
    optimized their corrosion control treatment.
    Any water
    system that exceeds the action level must also monitor
    their source water to determine whether treatment to
    remove lead in source water is needed.
    Any water
    system that continues to exceed the action level after
    installation of corrosion control and/or source water
    treatment must eventually re~1aceall lead service
    lines contributing in excess of 15 p~bof lead to
    drinking water.
    AnY water system that exceeds the
    action level must also undertake a public education
    program to inform consumers of ways they can reduce
    their exposure to potentially high levels of lead in
    drinking water.

    shown to cause stomach and intestinal distress, liver
    and kidney damage, and anemia.
    Persons with Wilson’s
    disease may be at a higher risk of health effects due
    to copper than the general public.
    USEPA’s national
    primary drinking water regulation requires all public
    water systems to install optimal corrosion control to
    minimize copper contamination resulting from the
    corrosion of olumbing materials.
    Public water systems
    serving 50,000 people or fewer that have copper
    concentrations below 1.3 parts per million (~~m)in
    more than 90
    of tap water samples
    (the USEPA “action
    level”)
    are not required to install or improve their
    treatment.
    Any water system that exceeds the action
    level must also monitor their source water to determine
    whether treatment to remove copper in source water is
    needed.
    15)
    Asbestos.
    The United States Environmental Protection
    Agency
    (USEPA) sets drinking water standards and has
    determined that asbestos fibers greater than
    10 micrometers in length are a health concern at
    certain levels of exposure.
    Asbestos is a naturally
    occurring mineral.
    Most asbestos fibers in drinking
    water are less than 10 micrometers in length and occur
    in drinking water from natural sources and from
    corroded asbestos—cement pipes in the distribution
    system.
    The major uses of asbestos were in the
    production of cements, floor tiles, paper products,
    paint, and caulking; in transportation-related
    applications; and in the production of textiles and
    plastics.
    -
    Asbestos was once a popular insulating and
    fire retardant material.
    Inhalation studies have shown
    that various forms of asbestos have produced lung
    tumors in laboratory animals.
    The available
    information on the risk of developing gastrointestinal
    tract cancer associated with the ingestion of asbestos
    from drinking water is limited.
    Ingestion of
    intermediate—range chrysolite asbestos fibers greater
    than 10 micrometers in length is associated with
    causing benign tumors in male rats.
    Chemicals that
    cause cancer in laboratory animals also may increase
    the risk of cancer in humans who are exposed over long
    periods of time.
    USEPA has set the drinking water
    standard for asbestos at 7 million long fibers per
    liter to reduce the potential risk of cancer or other
    adverse health effects which have been observed in
    laboratory animals.
    Drinking water which meets the
    USEPA standard is associated with little
    to- none of
    this risk and should be considered safe with respect to

    The United States
    Environmental Protection Agency
    (USEPA) sets drinking
    water standards and has determined that barium is a
    health concern at certain levels of exposure.
    This
    inorganic chemical occurs naturally in some aquifers
    that serve as sources of around—water.
    It is also used
    in oil and gas drilling muds,
    automotive paints,
    bricks, tiles, and iet fuels.
    It aenerallv aets into
    drinking water after dissolving from naturally
    occurring minerals in the ground.
    This chemical may
    damage the heart and vascular system. and is associated
    with high blood pressure in laboratory animals such as
    rats exposed to high levels during their lifetimes.
    In
    humans. USEPA believes that effects from barium on
    blood pressure should not occur below
    2 parts per
    million
    (ppm)
    in drinking water.
    USEPA has set the
    ~inking
    water standard for barium at
    2 parts per
    million (~~m)to protect against the risk of these
    adverse health effects.
    Drinking water that meets the
    USEPA standard is associated with little to none of
    this risk and
    is considered safe with respect to
    barium.
    17)
    Cadmium.
    The United States Environmental Protection
    Agency
    (USEPA) sets drinking water standards and has
    determined that cadmium is a health concern at certain
    levels of exposure.
    Food and the smoking of tobacco
    are common sources of general exposure.
    This inorganic
    metal is a contaminant in the metals used to galvanize
    pipe.
    It generally gets into water by corrosion of
    galvanized pipes or by improper waste disposal.
    This
    chemical has been shown to damage the kidney in animals
    such as rats and mice when the animals are exposed at
    high levels over their lifetimes.
    Some industrial
    workers who were exposed to relatively large amounts of
    this chemical during working careers also suffered
    damage to the kidney.
    USEPA has set the drinking water
    standard for cadmium at 0.005 parts per million
    (ppm)
    to protect against the risk of these adverse health
    effects.
    Drinking water that meets the USEPA standard
    is associated with little to none of this risk and is
    considered safe with respect-to cadmium.
    18)
    Chromium.
    -
    The-United States Environmental Protection
    Agency
    (USEPA) sets drinking water standards and has
    determined that chromium is a health concern at certain
    levels of exposure.
    This inorganic metal occurs
    naturally in the ground and is often used in the
    q

    164
    electroplating of metals.
    It generally gets into water
    from runoff from old mining operations and improper
    waste disposal from plating operations.
    This chemical
    has been shown to damage the kidney, nervous system,
    and the circulatory system of laboratory animals such
    as rats and mice when the animals are exposed at high
    levels. Some humans who were exposed to high levels of
    this chemical suffered liver and kidney damage,
    dermatitis and respiratory problems.
    USEPA has set the
    drinking water standard for -chromium at 0.1 parts per
    million
    (ppm) to protect against the risk of these
    adverse health effects.
    Drinking water that meets the
    USEPA standard is associated with little to none of
    this risk and is considered safe with respect to
    chromium.

    determined that mercury is a health concern at certain
    levels of exposure.
    This inorganic metal is used in
    electrical equipment and some water pumps.
    It usually
    gets into water as a result of improper waste disposal.
    This chemical has been shown to damage the kidney of
    laboratory animals such as rats when the animals are
    exposed at high levels over their lifetimes.
    USEPA has
    set the drinking water standard for mercury at 0.002
    parts per million
    (ppm) to protect against the risk of
    these adverse health effects.
    Drinking water that
    meets the USEPA standard is associated with little to
    none of this risk and is considered safe with respect
    to mercury.
    20)
    Nitrate.
    The United States Environmental Protection
    Agency
    (USEPA)
    sets drinking water standards and has
    determined that nitrate poses an acute health concern
    at certain levels of exposure.
    Nitrate is used in
    fertilizer and is found in sewage and wastes from human
    and/or farm animals and generally gets into drinking
    water from those activities.
    Excessive levels of
    nitrate in drinking water have caused serious illness
    and sometimes death in infants under six months of age.
    The serious illness in infants is caused because
    nitrate is converted to nitrite in the body.
    Nitrite
    interferes with the oxygen carrying capacity of the
    child’s blood. This is an acute disease in that
    symptoms can develop rapidly in infants.
    In most
    cases, health deteriorates over a period of days.
    Symptoms include shortness of breath and blueness of
    the skin.
    Clearly, expert medical advice should be
    sought immediately if these symptoms occur.
    The
    purpose of this notice is to encourage parents and
    other responsible parties to provide infants with an

    alternate source of drinking water.
    Local and State
    health authorities are the best source for information
    concerning alternate sources of drinking water for
    infants. USEPA has set the drinking water standard at
    10 parts per million
    (ppm)
    for nitrate to protect
    against the risk of these adverse effects.
    USEPA has
    also set a drinking water standard for nitrite at 1
    ppm.
    To allow for the fact that the toxicity of
    nitrate and nitrite are additive.
    USEPA has also
    established a standard for the sum of nitrate and
    nitrite at 10 ppm.
    Drinking water that meets the USEPA
    standard is associated with little to none of this risk
    and is considered safe with respect to nitrate.
    21)
    Nitrite.
    The United States Environmental Protection
    Agency
    (USEPA) sets drinking water standards and has
    determined that nitrite poses an acute health concern
    at certain levels of exposure.
    This inorganic chemical
    is used in fertilizers and is found in sewage and
    wastes from humans and/or farm animals and generally
    gets into drinking water as a result of those
    activities.
    While excessive levels of nitrite in
    drinking water have not been observed, other sources of
    nitrite have caused serious illness and sometimes death
    in infants under six months of age.
    The serious
    illness in infants is caused because nitrite interferes
    with the oxygen carrying capacity of the child’s blood.
    This is an acute disease in that symptoms can develop
    rapidly.
    However,
    in most cases, health deteriorates
    over a period of days.
    Symptoms include shortness of
    breath and blueness of the skin.
    Clearly, expert
    medical advice should be sought immediately if these
    symptoms occur.
    The purpose of this notice is to
    encourage parents and other responsible parties to
    provide infants with an alternate source of drinking
    water.
    Local and State health authorities are the best
    source for information concerning alternate sources of
    drinking water for infants.
    USEPA has set the drinking
    water standard at 1 part per million
    (ppm)
    for nitrite
    to protect against the risk of these adverse effects.
    USEPA has also set a drinking water standard for
    nitrate (converted to nitrite in humans)
    at
    10 ppm and
    for the sum of nitrate and nitrite at 10 ppm.
    Drinking
    water that meets the USEPA standard is associated with
    little to none of this risk and is considered safe with
    respect to nitrite.
    22)
    Selenium.
    The United States Environmental Protection
    Agency
    (USEPA) sets drinking water standards and has
    determined that selenium is a health concern at certain
    high levels of exposure.
    Selenium is also an essential
    nutrient at
    low levels of exposure.
    This inorganic

    166
    chemical is found naturally in food and soils and is
    used in electronics, photocopy operations, the
    manufacture of glass,
    chemicals, drugs, and as a
    fungicide and a feed additive.
    In humans, exposure to
    high levels of selenium over a long period of time has
    resulted in a number of adverse health effects,
    including a loss of feeling and control in the arms and
    legs.
    USEPA has set the drinking water standard for
    selenium at 0.05 parts per million
    (ppm)
    to protect
    against the risk of these adverse health effects.
    Drinking water that meets the USEPA standard is
    associated with little to none of this risk and is
    considered safe with respect to selenium.
    23)
    Acrylamide.
    The United States Environmental Protection
    Agency
    (USEPA) sets drinking water standards and has
    determined that acrylamide is a health concern at
    certain levels of exposure.
    Polymers made from
    acrylamide are sometimes used to treat water supplies
    to remove particulate contaminants.
    Acrylamide has
    been shown to cause cancer in laboratory animals such
    as rats and mice when the animals are exposed at high
    levels over their lifetimes.
    Chemicals that cause
    cancer in laboratory animals also may increase the risk
    of cancer in humans who are exposed over long periods
    of time.
    Sufficiently large doses of acrylamide are
    known to cause neurological injury.
    USEPA has set the
    drinking water standard for acrylamide using a
    treatment technique to reduce the risk of cancer or
    other adverse health effects which have been observed
    in laboratory animals.
    This treatment technique-limits
    the amount of acrylamide in the polymer and the amount
    of the polymer which may be added to drinking water to
    remove particulates.
    Drinking water systems which
    comply with this treatment technique have little to no
    risk and are considered safe with respect to
    acrylamide.

    INTRODUCTION
    The United States Environmental Protection Agency
    (EPA) and
    linsert name of water sup~lier1are concerned about lead in your
    drinking water.
    Although most homes have very low levels of lead
    in their drinking water. some homes in the community have lead
    levels above the EPA action level of 15 carts ~er billion (~pb).
    ;,
    ~~--~c-~

    179
    or 0.015 milligrams of lead per liter of water (mg/L).
    Under
    Federal law we are required to have a program in place to
    minimize lead in your drinking water by
    linsert date when
    corrosion, control will be completed for your system1~. This
    program includes corrosion control treatment,
    source water
    treatment,
    and public education.
    We are also required to replace
    each lead service line that we control if the line contributes
    lead concentrations of more than 15 ppb after we have completed
    the comprehensive treatment program.
    If you have any questions
    about how we are carrying out the requirements of the lead
    regulation please give us a call at insert
    water system’s phone
    numberl.
    This brochure explains the simple steps you can take to
    protect you and your family by reducing your exposure to lead in
    drinking water.
    ~j.
    HEALTH EFFECTS OF LEAD
    Lead is a common metal found throuahout the environment in lead—
    based paint,
    air,- soil, household dust,
    food,
    certain types of
    pottery porcelain and pewter, and water.
    Lead can pose a
    significant risk to your health if too much of it enters your
    body.
    Lead builds up in the body over many years and can- cause
    damage to the brain,
    red blood cells and kidneys.
    The greatest
    risk is to young children and pregnant women.
    Amounts of lead
    that won’t hurt adults can slow down normal mental and physical
    development of growing bodies.
    In addition,
    a child at play
    often comes into contact with sources of lead contamination
    ——
    like dirt and dust
    --
    that rarely affect an adult.
    It is
    important to wash children’s hands and toys often,
    and to try to
    make sure they only put food in their mouths.
    fl
    LEAD IN DRINKING WATER
    ~j.
    Lead in drinking water, although rarely the sole cause
    of lead poisoning, can significantly increase a
    person’s total lead exposure, ~articularlv the exposure
    of infants who drink baby formulas and concentrated
    luices that are mixed with water.
    The EPA estimates
    that drinking water can make up 20 percent or more of a
    person’s total exposure to lead.
    ~j.
    Lead is unusual amona drinking water contaminants in
    that it seldom occurs naturally in water supplies like
    rivers and lakes.
    Lead enters drinking water primarily
    as
    a result of the corrosion,
    or wearing away..
    of
    materials containing lead in the water distribution
    system and household plumbing.
    These materials include
    lead—based solder used to loin copper pipe, brass and
    chrome plated brass faucets, and in some cases, pipes
    made of lead that connect your house to the water main
    (service lines).
    In 1986. Congress banned the use of
    lead solder containing greater than 0.2
    lead, and
    0 R2-0309

    180
    restricted the lead content of faucets, pipes and other
    plumbing materials to 8.0.
    QJ.
    When water stands in lead pipes or plumbing systems
    containing lead for several hours or more, the lead may
    dissolve into your drinking water.
    This means the first
    water drawn from the tap in the morning, or later in
    the afternoon after returning from work or school,
    can
    contain fairly high levels of lead.
    j)
    STEPS YOU CAN
    TAKE
    IN THE HOME TO REDUCE EXPOSURE TO LEAD IN
    DRINKING WATER
    ~j
    Despite our best efforts mentioned earlier to control
    water corrosivity and remove lead from the water
    supply.
    lead levels
    in some homes or buildings can be
    high.
    To find out whether you need to take action in
    your own home,
    have your drinking water tested to
    determine if it contains excessive concentrations of
    lead.
    Testing the water is essential because you
    cannot see, taste, or smell lead in drinking water.
    Some local laboratories that can provide this service
    are listed at the end of this booklet.
    For more
    information on having your water tested, please call
    insert
    phone number of water systemi.
    ~
    If a water test indicates that the drinking water drawn
    from
    a tap in your home contains lead above 15 ppb,
    then you should take the following precautions:
    fl
    Let the water run from the tap before using it for
    drinking or cooking any time the water in a faucet
    has gone unused for more than six hours.
    The
    1on~erwater resides in your home’s plumbing the
    more lead it may contain.
    Flushing the tap means
    running the cold water faucet until the water gets
    noticeably colder, usually about 15—30 seconds.
    If your house has a lead service line to the water
    main, you may have to flush the water for a longer
    time, perhaps one minute. before drinking.
    Although toilet flushing or showering flushes
    water through a portion of your home’s plumbing
    system. you still need to flush the water in each
    faucet before using it for drinking or cooking.
    Flushing tap water is a simple and inexpensive
    measure you can take to protect your family’s
    health.
    It usually uses less than one or two
    ~ailons of water and costs less than
    Iinsert a
    cost estimate based on flushing two times a day
    for 30 days
    per month.
    To conserve water, fill
    a
    couple of bottles for drinking water after
    flushing the tap,
    and whenever possible use the
    0
    ~~2-O3
    I
    0

    181
    first flush water to wash the dishes or water the
    plants.
    If you live in a high-rise building,
    letting the water flow before using it may not
    work to lessen your risk from lead.
    The plumbing
    systems have more,
    and ‘sometimes larger pipes than
    smaller buildings.
    Ask your landlord for help in
    locating the source of the lead and for advice on
    reducing the lead level.
    jJJ..
    Try not to cook with,
    or drink water from the hot
    water tap.
    Hot water can dissolve more lead more
    quickly than cold water.
    If you need hot water,
    draw water from the cold ta~and heat it on the
    stove.
    iii) Remove loose lead solder and debris from the
    plumbing materials installed in newly constructed
    homes,
    or homes
    in which the plumbing has recently
    been replaced~by removing the faucet strainers
    from all taps and running the water from 3 to 5
    minutes.
    Thereafter, periodically remove the
    strainers and flush out any debris that has
    accumulated over time.
    i~1
    If your copper pipes are loined with lead solder
    that has been installed illegally since it was
    banned in 1986, notify the plumber who did the
    work and request that he or she replace the lead
    solder with lead—free solder.
    Lead solder looks
    dull gray.
    and when scratched with a key looks
    shiny.
    In addition, notify your State (insert
    name of department responsible for enforcing the
    Safe Drinking Water Act in your Statel about the
    violation.
    yI
    Determine whether or not the service line that
    connects your home or apartment to the water main
    is_made_of lead.
    The best way to determine if
    your service line is made of lead is by either
    hiring a licensed plumber to inspect the line or
    by contacting the plumbing contractor who
    installed the line.
    You can identify the plumbing
    contractor by checking the city’s record of
    building permits which should be maintained in the
    files of the
    insert
    name of department that
    issues building permits).
    A licensed plumber can
    at the same time check to see if your homes’s
    plumbing contains lead solder,
    lead pipes,
    or pipe
    fittings that contain lead.
    The public water
    system that delivers water to your home should
    also maintain records of the materials located in
    the distribution system.
    If the service line that
    0t14-2-031
    I

    182
    connects your dwelling to the water main
    contributes more than 15 ppb to drinking water,
    after our- comprehensive treatment pro~am is in
    place. we are required to replace the line.
    If
    the line
    is only partially controlled by the

    Have an electrician check your wiring.
    If
    grounding wires from the electrical system are
    attached to your pipes, corrosion may be greater.
    Check with a licensed electrician or your local
    electrical code to determine if your wiring can be
    grounded elsewhere.
    DO NOT attempt to change the
    wiring yourself because improper grounding can
    cause electrical shock and fire hazards.

    The steps described above will reduce the lead
    concentrations in your drinking water.
    However,
    if a
    water test indicates that the drinking water coming
    from your ta~contains lead concentrations in excess of
    15 p~bafter flushing, or after we have completed our
    actions to minimize lead levels, then you maY want to
    take the following additional measures:
    j).
    Purchase or lease a home treatment device.
    Home
    treatment devices are limited in that each unit
    treats only the water that flows from the faucet
    to which it is connected, and all of the devices
    require periodic maintenance and replacement.
    Devices such as reverse osmosis systems or
    distillers can effectively remove lead from your
    drinking water.
    Some activated carbon filters may
    reduce_lead levels at the tap, however all lead
    reduction- claims should be investigated.
    Be sure
    to check the actual performance of a specific home
    treatment device before and after installing the
    unit.
    jJJ..
    Purchase bottled water for drinking and cooking.
    Q1
    You can consult a variety of sources for additional
    information.
    Your family doctor or pediatrician can
    perform a blood test for lead and provide you with
    information about the health effects of lead.
