Proposal for Public Comment.
Proposed 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.
B.
Forcade concurred.

Section 611.111
Section 1415 Variances
This Section is intended as a State equivalent of Section
1415(a) (I) (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
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
0 139-0212
33
monitoring requirements of Section 611.646(e) and
(f)
(Phase I VOCs and Phase II VOC5), Section 611.648(a)
(for Phase II SOCs)
and Section 611.510(a)
(for
unregulated organic contaminants) on the basis of
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. Ada. 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:
i)
A GWS must consider well depth,
soil
type,
and well casing integrity, and
ii)
A SWS must consider watershed
protection; and
E)
For Phase II SOC5 and unregulated organic
contaminants (pursuant to Section 611.631 or
611.648):
i)
Elevated nitrate levels at the water
source; and
ii)
The use of PCB5 in equipment used in the
production,
storage, or distribution of
water
(including pumps, transformers,
0139-0211

requirement; and
2)
The system has applied BAT as identified in
Subpart G.
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).
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. Ada. Code 104.
f)
The Board will not grant a variance:
1)
From the MCL for total coliforms; provided,
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.
g)
As used in this Section and Section 611. 112,
“unreasonable risk to health level”
(“URTH level”)
0139-0213
36
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.

Section 611.112
Section 1416 Variances
This Section is intended as a State equivalent of Section 1416 of
the SDWA.
a)
The Board may grant a supplier a variance from any
requirement respecting an MCL or treatment technique
requirement of an NPDWR in this Part.
1)
The supplier shall file a variance petition
pursuant to 35 Ill. Ada. 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)
Due to compelling factors
(which may include
economic factors), the supplier is unable to
comply with the MCL or treatment technique
requirement;
0139-O21~4
37
2)
The supplier was:
A)
In operation on the effective date of the M~L
or treatment technique requirement; or
B)
Not in operation on the effective date of the
MCL or treatment technique requirement and no
reasonable alternative source of drinking
water is available to the supplier; and
3)
The variance will not result in an unreasonable
risk to health.
C)
The Board will prescribe a schedule for:
1)
Compliance,
including increments of progress, by
the supplier, with each MCL and treatment
technique requirement with respect to which the
variance was granted; and
2)
Implementation by the supplier, during the period
ending on the date when compliance is required, of
each additional control measure for each
contaminant subject to the MCL or treatment
technique requirement.
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;
but no schedule shall extend more than 12 months after
the date of the variance, except as follows:
1)
The Board may extend the date for a period not
tc~
exceed three years beyond the date of the variance
if the supplier establishes:
that it is taking

This provision,
which corresponds with 40 CFR 141.11,
was formerly the only listing of )JCLs for inorganic
parameters.
However, USEPA added another listing of
inorganic MCLs at 40 CFR 141.62 at 56 Fed. Reg. 3594
(Jan.
30,
1991).
Following the changing USEPA
codification scheme creates two listings of MCL5:
one
at this Section and one at Section 611.301.
This also
causes fluoride to appear in both listings with the
same MeL.
The impact of the two listings are distinct._
Further, under the federal scheme. there is no MCL for
copper.
Rather, there is an “action level”, which if
exceeded causes the supmlier to undertake certain
actions.
See Section 611.350.
The Board retained the
MCL because its impact is distinct from that of the
action level for copper.

SUBPART N:
INORGANIC MONITORING AND ANALYTICAL REQUIREMENTS
Section 611.560
Turbidity
The requirements in this Section apply to unfiltered PWSs until
December 30,
1991, unless the Agency has determined prior to that
date that filtration is required.
The requirements in this
Section apply to filtered PWSs until June 29,
1993.
The
requirements in this Section apply to unfiltered PWSs that the
Agency has determined must install filtration, until June 29,
1993, or until filtration is installed,
whichever is later.
a)
Suppliers shall take samples at representative entry
point(s) to the distribution system at least once per
day, for the purposes of making turbidity measurements
to determine compliance with Section 611.320.
1)
If Public Health determines that a reduced
sampling frequency in a non-CWS will not pose a
risk to public health,
it may reduce the required
sampling frequency. The option of reducing the
turbidity frequency will be permitted only in
those suppliers that practice disinfection and
0139-0286
109
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)
tJSEPA 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
(Amco-AEPA-1 Polymer).
b)
If the result of a turbidity analysis indicates that
the maximum allowable limit has be~nexceeded,
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.
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.
c)
Sampling for non-CWS5 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.

Monitoring Requirements for Old Inorganic
MCL5
a)
Analyses for the purpose of determining compliance with
the old inorganic MCL5 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 CWS5 utilizing only groundwater
sources must be repeated at three—year intervals.
3)
This subsection corresponds with 40 CFR
141.23(1) (3)
(19942), 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.
This statement maintains structural consistency
with USEPA rules
4)
This subsection corresponds with 40 CFR
141.23(1)(4) (l99~), which authorizes the state
to determine compliance and initiate enforcement
action.
This authority exists through the
authorization of the Act, not therQugh federal
rules.
This statement maintains structural
consistency with USEPA rules.
b)
If the result of an analysis made under subsection
(a)
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), 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.
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
0139-0296
119
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)
(1994~),which pertains to monitoring for the repealed
old MCL for nitrate.
The Board has followed the USEP.A
action and repealed that old MCL.
This statement
maintains structural consistency with USEPA rules.
e)
This subsection corresponds with 40 CFR 141.23(p)
(1994~),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.
This statement

Section 611.630
Special Monitoring for Sodium
a)
CWS
suppliers shall collect and analyze one sample per
plant at the entry point of the distribution system for
the determination of sodium concentration levels;
samples must be collected and analyzed annually for
CWSS 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
0 39-0300
123
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:

heptachlor, and heptachlor
epoxide are also “Phase II SOCs”.
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
SOCs 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 SOCs.
“Phase II SOCs” means:
Alachlor
Atrazine
Carbofuran
Chlordane
Dibromochloropropane
Ethylene dibromide

The MCLS for these contaminants are
located at Section 611.311.
The effectiveness
of the Section 611.311 MCLs for aldicarb. aldicarb
sulfone, and aldicarb sulfoxide are
administratively stayed until the Board takes
further administrative action to end this stay.
However,
suppliers must monitor for these three
SOCs pursuant to Section 611.648.
See 40 CFR
0 j39-0302
125

___________
Section 611.646
Phase I and Phase II Volatile Organic
Contaminants
Monitoring of the Phase
I VOCs and Phase II VOC5 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
0139-0303
126
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~). This is
a “trigger level” for Phase I VOCS and Phase II
VOC5 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) 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.
BOARD
NOTE:
Derived from 40 CFR 136, Appendix B
(19942).
The method detection limit is determined
by the procedure set forth in 40 CFR 136, Appendix
B.
See subsection
(t).
b)
Required sampling.
Each supplier shall take a minimum
of one sample at each sampling point at the times
required in subsection
(u).
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
0 139-030L
127
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) derived from
40 CFR 141.24(f) (1) through (f)(3)
(1994.2).
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 VOCs and Phase II
VOCs
as
allowed
in
subsection
(r)
(1)
has
been
completed
by
December
31,
1992, and the supplier did 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
VOCS,
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) 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).
BOARD NOTE:
Derived from 40 CFR 141.24(f) (7)
and
(f).(1O) (199~).
Provisions concerning the term of the
waiver appear below in subsections
(i)
and
(j).
The
definition of “detect”, parenthetically added to the
federal counterpart paragraph is in subsection
(a).
0139-0305
128
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)
sought
pursuant to subsection
(g).
i)
A SEP issued to a GWS pursuant to subsection
(g)
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)
and submitted pursuant to subsection
(g), by taking one
sample. at each sampling point and reapplying for a SEP
pursuant to subsection (g).
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
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)
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 VOCs 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 SWS5.
The Board has consolidated
the common requirements of both paragraphs into
subsection
(g).
Subsection
(j)
represents the
elements unique to SWSs and mixed systems,
and
subsection
(i)
relates to GWS5.
Although 40 CFR
141.24(f) (7) and (f)(10) are silent as to mixed
0139 -0306
129
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 VOC5,
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 MCL.
B)
A request for a SEP must include the
following minimal information:
i)
For a GWS, two quarterly samples.
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 SEP5 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)
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).
5)
A GWS supplier that has detected one or more of
the two—carbon contaminants listed in subsection
01390307
130
(k) (5) (A)
shall monitor quarterly for vinyl
chloride as described in subsection
(k) (5) (B),
subject to the limitation of subsection
(k) (5) (C).
A)
Two-carbon contaminants
(Phase I or II VOC):
1,2-Dichloroethane
(Phase
I)
1,1-Dichloroethylene (Phase
I)
cis-1,2-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).
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
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).
1)
Quarterly monitoring following MCL violations.
1)
Suppliers that violate an MCL for one of the Phase
I VOCs,
including vinyl chloride, or Phase II
VOCs,
as determined by subsection
(0),
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
01390308
131
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)
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 sooi~aspossible, but no
later than 14 days after the supplier receives
notice of the detection.
2)
Averaging is as specified in subsection (o).
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.
0)
Compliance with the MCL5 for the Phase I VOC5 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.
0139-0309
132
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~,atany 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.
p)
Analyses for the Phase
I VOC5 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:

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
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 MCL, 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).
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,
1,2—dichloroethane,
1,1,1-
trichloroethane, cis-1,2-dichloroethylene,
trans-i,2-
dichioroethylene or 1,1-dichloroethylene.
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
0139-0313
136
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
.1
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.
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-nil 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—nil or equal larger amounts of each
aqueous sample
(up to 5 samples are allowed)
into a 25-ml 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.

CWS
is deemed to be out of compliance immediately.
For
CWS
suppliers
that
only take one sample per location
because
none

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”.
“Detection limit” means the level of the
contaminant of interest that is specified in
subsection
(r).
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).
BOARD NOTE:
USEPA stayed the effective date of the
MCLS for aldicarb. aldicarb sulfone. and aldicarb
sulfoxide at 57 Fed. Req.
22178 (May 27,
1991).
Section 611.311(c)
includes this stay.
However,
despite the stay of the effectiveness of the MCLs for
these three SOCs,
suppliers must monitor for them.
c)
Sampling points.
1)
Sampling points for GWS5.
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.
0139-0319
142
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 distributi’n 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)
derived from
40 CFR 141.24(h) (1) through
(h)(3)
(199~2J.
d)
Monitoring frequency:

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).
A
SEP from the requirement of subsection
(d)
shall last
for only a single three—year compliance period.
f)
Vulnerability Assessment.
The Agency shall grant
a SEP
0
39-0320
143
from the requirements of subsection
(d)
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:
1)
For a GWS, two quarterly samples.
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 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 SEP5 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)
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).
5)
Monitoring for related contaminants.
U 139-0321
144
A)
If monitoring results in detection of one or
more of the related contaminants listed in
subsection
(g) (5) (B), subsequent monitoring
shall analyze for all the related compounds
in
the
respective
group.
B)
Related contaminants:
i)
first group:
aldicarb
aldicarb sui~fone
aldicarb sulfoxide
ii)
second group:
heptachlor
heptachlor epoxide,
h)
Quarterly monitoring following MCL violations.
1)
Suppliers that violate an MCL for one of the Phase
II SOC5, as determined by subsection
(k), 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)
if
it detects any Phase II SOC.
01390322
145
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).
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),
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.
k)
Compliance with the MCL5 for the Phase II SOC5 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
0139-0323
146
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.

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
(mg/L).
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.
0139-0331
154
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
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.

(19912.).
10)
Microbiological contaminants
(for use when there is a
violation of the treatment technique requirements for
filtration and disinfection in Subpart B).
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
0j39-0332
155
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
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 ColiformsfE.
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.
coli 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
0133-0333
156
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 coliforms and E.
coli
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:
To

reserved
by
UCEPA.
This
atatomont
maintains
structural
consistency with UCEPA rulos.Lead.
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 freauently 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
primary 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
50,000 people or fewer that have lead concentrations
below 15 carts per billion
(ppb)
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

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
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 replace all lead service
lines contributing in excess of 15 ppb of 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.
This subsection corresponds with 40 CFR 141.32(c) (14),
reserved by UCEPA.
This statement maintains structural
consistency with UCEPA rulcs.Copper.
The United States
Environmental Protection Agency
(USEPA)
sets drinking
water standards and has determined that copper is a
health concern at certain exposure levels.
Copper, a
reddish-brown metal,
is often used to plumb residential
and commercial structures that are connected to water
distribution systems.
Co~~er
contaminating drinking
water as a corrosion by—product occurs as the result of
the corrosion of copper pipes that remain in contact
with water for a prolonged period of time.
Co~~eris
an essential nutrient, but at high doses it has been
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 plumbing 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 ta~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.

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
asbestos.

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 ground—water.
It is also used
in
oil
and
gas
drilling
muds,
automotive
paints,
bricks,
tiles, and jet fuels.
It generally gets 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
drinking water standard for barium at
2 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
barium.

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
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.

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.

INTRODUCTION
The United States Environmental Protection A~encv (EPA)
and

drinking
water.
Although
most homes have verY low levels of lead
in their drinking water, some homes

EPA
action level of
15 Parts ~er billion (~pb),
or 0.015 milligrams of lead ~er liter of water
(mci/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 system.
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 ~pb after we have completed
the comprehensive treatment program.
If you have any auestions
about how, we are carrying out the reguirements of the lead
regulation please give us a call at
Finsert 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.
21.
HEALTH EFFECTS OF LEAD
Lead is
a common metal found throughout the environment in lead-
based paint,
air, soil,
household dust.
food.
certain tv~esof
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
dama~eto 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.

LEAD IN DRINKING WATER
~j
Lead in drinking water, althou~hrarely the sole cause
of lead poisoning, can significantly increase a
person’s total lead exposure. particularly 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 amon~drinking water contaminants in
that it seldom occurs naturally j~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 ~eater
than 0.2
lead,
and
restricted the lead content of faucets.
pipes and other
Plumbing materials to 8.0.
~
When water stands in
leaçl Pipes or plumbing systems
containing lead for sevetal 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 leve4s of lead.
j)
STEPS YOU
CAN
TAKE IN THE HOME TO REDUCE EXPOSURE TO LEAD IN
DRINKING WATER
~
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
Iinsert Phone number of water system.
~j
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:
~jj
Let the water run from the tap before using
it for
013SU353
176
drinking or cooking any time the water in a faucet
has gone unused for more than six hours.
The
longer water resides in your home’s plumbing the
more lead
it may contain.
Flushing the ta~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
gallons of water and costs less than
Iinsert a
cost estimate based on flushing two times a day
for 30 daysi per month.
To conserve water,
fill a
couple of bottles for drinking water after
flushing the tap,
and whenever possible use the
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 lar~erpipes than
smaller buildings.
Ask your landlord for help in
locating the source of the lead and for advice on
reducing the lead level.
jj).
Try not to cook with,
or drink water from the hot
water tap.
Hot water can dissolve more lead more
guickly than cold water.
If you need hot water.
draw water from the cold tap 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.
jyj
If your copper pipes are joined with lead solder
that has been insta4.led illegally since
it was
banned in 1986,
notj.fy 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
linsert

177
name of department responsible for enforcing the
Safe Drinking Water Act in your State
about the
violation.
yl
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 ~1umber 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
Iinsert name of department that
issues building permitsi.
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
connects your dwelling to the water main
contributes more than 15 ppb to drinking water,
after
our
comprehensive
treatment
program
is
in
place, we are reauired to replace the line.
If
the line is only partially controlled by the
Sinsert name of the
city., county, or water system
that controls the linel, we are reauired to
provide you with information on how to replace
Your portion of the service line, and offer to
rePlace that portion of the line at your expense
and take a follow-up ta~water samPle within 14
days
of
the
replacement.
Acceptable
replacement
alternatives inc1ud~copper. steel,
iron, and
plastic pipes.
yfl
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 jm~ropergrounding can
cause electrical shock and fire hazards.
~j
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 tap contains lead concentrations in excess of
15 ~pb after flushing.
or after we have completed our
actions to minimize lead levels, then you may want to
take the following additional measures:
at

178
ii.
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.
pj
You can consult a variety of sources for additional
information.
