Final Order.
ORDER OF THE BOARD
(by
3.
Anderson):
Pursuant to Sections 17.5 of the Environmental Protection
Act
(Act),
the Board is amending 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 order is supported by an opinion adopted on the same
day.
The Board received public comment on the proposal for a
period of 45 days following its publication in the Illinois
Register on April 10,
1992
(Part 611,
at 16
Ill. Reg. 55826).
The complete text of the adopted 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 by the
Board on the

611.211:
a)
Disinfection.
1)
The supplier shall meet the requirements of
Section 611.241(a) at least 11 of the 12 previous
months
that the system served water to the public,
on an ongoing basis, unless the system fails to
meet the requirements during
2
of
the
12
previous
months
that
the
system
served
water
to
the
public,
and
the
Agency determines that at least one of
these
failures was caused by circumstances that
were
unusual
and
unpredictable.
2)
The supplier shall meet the following requirements
at
the
times
specified
for
each:
~J
The requirements
of
Section
611.241(b)ll),
at

water
to
the
public; and
~j
The
requirements
of
Section
611.
241(b)
(2)
at
all
times
the system serves water to the
public~unless the Agency determines that any
such failure was caused by circumstances that
were
unusual
and
unpredictable.
3)
The supplier shall meet the requirements of
Section
611.241(c)
at
all
times
the

Each
supplier
that
does
not

provide disinfection treatment as follows:
a)
The
disinfection
treatment
must
be
sufficient
to
ensure
at least 99.9 percent
(3—log)
inactivation of Giardia
laiublia
cysts
and
99.99 percent

inactivation of
viruses,
every day the system serves water to the
0137-0376
41
public,
except
any
one
day
each
month.
Each
day
a
system serves water to the public, the supplier shall
calculate
the
CT~ value(s)
from
the
system’s
treatment
parameters
using
the
procedure
specified
in
Section
611.532(c)
and determine whether this value(s)
is
sufficient
to
achieve
the
specified
inactivation
rates
for
Giardia
lamblia
cysts
and
viruses.
1)
If a system uses a disinfectant other than
chlorine,
the
system may demonstrate to the
Agency, through the use of an Agency—approved
protocol for on—site disinfection challenge
studies
or
other
information,
that CT99.9~
values
other
than
those
specified
in Section 611.Appendix
B,
Tables
2.1
and
3.1
or
other
operational
parameters are adequate to demonstrate that the
system
is
achieving
minimum
inactivation
rates
required
by
this
subsection.
2)
The
demonstration
must
be
made
by
way
of
special
exception permit application.
b)
The disinfection system must have either:
1)
Redundant
components,
including
an
auxiliary
power
supply with automatic start—up and alarm to ensure
that disinfectant application is maintained
continuously
while
water
is
being
delivered
to
the
distribution system; or
2)
Automatic
shut-off
of
delivery
of
water
to
the
distribution
system
whenever there is less than
0.2 mg/L
of
RDC
in
the
water.
If
the
Agency
determines,
by
special
exception
permit,
that
automatic
shut—off
would
cause unreasonable risk
to health or interfere with fire protection, the
system
shall
comply
with
subsection
(b) (1).
c)
The
RDC
in
the
water
entering
the
distribution
system,
measured as specified in Section 611.531(e)
and
611.532(e),
cannot
be
less
than
0.2

for
more
than
4 hours.
d)
RDC
in the distribution system.
1)
The
RDC
in
the
distribution
system, measured as
total
chlorine,
combined
chlorine
or
chlorine

as
specified
in
Section
Section
611.531(e)
and
611.532(e~),
cannot
be
undetectable
in
more
than
5 percent
of
the
samples
each
month
for any two consecutive months that the system

RDC
for
purposes of determining compliance with this
requirement.
Thus,
the

“V” in the following
formula cannot exceed 5 percent in one month,
for
any
two
consecutive

fl
A SWS or mixed system supplier shall take
a minimum of
one sample at points in the distribution system that
are representative of each source or at each entry
point to the system after treatment (“sampling point”).
gj
If the system draws water from more than one source and
sources gre combined before distribution, the supplier
shall sample at an entry point during periods of normal
operating conditions (when water representative of all
sources
is being used).
.i~i
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.

Suppliers shall take samples at the same sampling point
unless the Agency has granted a SEP allowing another
sampling point because conditions make another sampling
point more representative of the water from each source
or treatment plant.

limit on a case-by-case basis
if it determines that the
supplier has a logistical problem in collecting the
repeat samples within 24 hours that is beyond its
control.
In the case of an extension, the Agency shall
specify how much time the supplier has to collect the
repeat samples.
b)
The
supplier
shall
collect
at
least
one
repeat
sample
from
the
sampling
tap
where
the
original
total
coliforin—positive
sample
was
taken,
and
at
least
one
repeat
sample
at
a
tap
within
five
service
connections
upstream and at least one repeat sample at a tap within
five service connections downstream of the original
sampling site.
If a total coliforin-positive sample is
at the end of the distribution system, or one away from
the end of the distribution system, the Agency may
waive the requirement to collect at least one repeat
sample upstream or downstream of the original sampling
site.
c)
The supplier shall collect all repeat samples on the
same day, except that the Agency shall allow a supplier
with a single service connection to collect the
required set of repeat samples over a four—day period
or to collect a larger volume repeat sample(s)
in one
or more sample containers of any size, as long as the
total volume collected is at least 400 ml
(300 ml for
PWSs whichthat collect more than one routine sample per
month).
d)
If one or more repeat samples in the set is total
coliform-positive,
the supplier shall collect an
additional set of repeat samples in the manner
specified in subsections
(a) through
(c).
The
additional samples must be collected within 24 hours of
being notified of the positive result, unless the
Agency extends the limit as provided in subsection
(a).
The supplier shall repeat this process until either
total coljforins are not detected in one complete set of
repeat samples or the supplier determines that the MCL
01 3?-0392
57
for
total
coliforms
in
Section
611.325
has
been
exceeded
and
notifies
the
Agency.
e)
If
a
supplier
collecting
fewer
than
five
routine
samples/month
has
one
or
more
total
coliform—positive
samples and the Agency does not invalidate the
sample(s)
under
Section
611.523,
the
supplier
shall
collect at least five routine samples during the next
month the supplier provides water to the public, unless
the Agency determines that the conditions of subsection
(e) (1) or
(2)
are met.
This does not apply to the
requirement to collect repeat samples in subsections
(a) through
(d).
The supplier does not have to collect
the samples if:
1)
The Agency performs
a site visit before the end of
the next month the supplier provides water to the
public.
Although a sanitary survey need not be
performed, the site visit must be sufficiently
detailed to allow the Agency to determine whether
additional monitoring or any corrective action is
needed.
2)
The Agency has determined why the sample was total
coliforin-positive and establishes that the
supplier has corrected the problem or will correct
the problem before the end of the next month the
supplier serves water to the public.
A)
The Agency shall document this decision in
writing, and make the document available to
USEPA and the public.
The written
documentation must describe the specific
cause of the total coliform-positive sample
and what action the supplier has taken or
will take to correct the problem.
B)
The Agency cannot waive the requirement to
collect five routine samples the next month
the supplier provides water to the public
solely on the grounds that all repeat samples
are totaL. coliforin—negative.
C)
Under this subsection,
a supplier shall still
take at least one routine sample before the
end of the next month it serves water to the
public and use it to determine compliance
with the MCL for total coliforms in Section
611.325, unless the Agency has determined
that the supplier has corrected the
contamination problem before the supplier
took the set of repeat samples required in
0137-0393
58
subsections
(a)
through
(d), and all repeat
samples were total coliform-negative.
f)
After a supplier collects a routine sample and before
it learns the results of the analysis of that sample,
if it collects another routine sample(s)
from within
five adjacent service connections of the initial
sample, and the initial sample, after analysis,
is
found to contain total coliforms, then the supplier may
count the subsequent sample(s)
as a repeat sample
instead of as a routine sample.
g)
Results of all routine and repeat samples not
invalidated pursuant to Section 611.523 must be
included in determining compliance with the MCL for
total coliforms in Section 611.325.

Section 611.523
Invalidation of Total Coliform Samples
A total coliform—positive sample invalidated under this Section
does not count towards meeting the minimum monitoring
requirements.
a)
The Agency shall invalidate a total coliform-positive
sample only if the conditions of subsection
(a) (1),
j~j(2)~or
j~j(3)
are
met.
1)
The laboratory establishes that improper sample
analysis caused the total coliform—positive
result.
2)
The Agency, on the basis of the results of repeat
samples collected as required by Section
611.522(a) through
(d) determines that the total
coliform—positive sample resulted from a domestic
or other non-distribution system plumbing problem.
The Agency cannot invalidate a sample on the basis
of repeat sample results unless all repeat
sample(s)
collected at the same tap as the
original total coliform-positive sample are also
total coliform—positive,
and all repeat samples
collected within five service connections of the
original tap are total coliform—negative
(e.g.,
Agency cannot invalidate a total coliform-positive
sample on the basis of repeat samples if all the
repeat samples are total coliforin-negative, or
if
01
37-Q39L~
59
the
supplier
has
only
one
service connection).
3)
The
Agency
determines
that
there
are
substantial
grounds to believe that a total coliform-positive
result
is due to a circumstance or condition which
does not reflect water quality in the distribution
system.
In this case, the supplier shall still
collect all repeat samples required under Section
611.522(a) through
(d) and use them to determine
compliance with the MCL for total coliforins in
Section 611.325.
To invalidate a total coliforin—
positive sample under this subsection, the
decision with the rationale for the decision must
be documented in writing.
The Agency shall make
this document available to USEPA and the public.
The written documentation must state the specific
cause of the total coliform-positive sample,
and
what action the supplier has taken, or will take,
to correct this problem.
The Agency shall not
invalidate a total coliform-positive sample solely
on the grounds that all repeat samples are total
coliforin-negative.
b)
A laboratory shall invalidate a total coliform sample
(unless total coliforms are detected)
if the sample
produces a turbid culture in the absence of gas
production using an analytical method where gas
formation is examined (e.g.,
the Multiple-Tube
Fermentation Technique), produces a turbid culture in
the absence of an acid reaction in the P—A Coliform
Test,
or exhibits confluent growth or produces colonies
too numerous to count with an analytical method using a
membrane filter
(e.g., Membrane Filter Technique).
If
a laboratory jnvalidates a sample because of such
interference, the supplier shall collect another sample
from the same location as the original sample within 24
hours of being notified of the interference problem,
and have it analyzed for the presence of total
coliforms.
The supplier shall continue to re—sample
within 24 hours and have the samples analyzed until
it
obtains a valid result.
The Agency shall waive the 24-
hour time limit on a case—by—case basis,
if it is not
possible to collect the sample within that time.

NTF
Technique
using either five tubes
(20-mi sample portions or a
single culture bottle containing the culture medium for
the
MTF
Technique,
i.e.,
lauryl tryptose broth
(formulated as described in Standard Methods,

as long as a 100-mi water sample is
used in the analysis.
e)
Suppliers shall conduct fecal coliform analysis
in
accordance with the following procedure:
0137-0396
61
1)
When the
MTF
Technique or P-A Coliform Test is
used
to
test
for
total
coliforim~,
shake
the
lactose-positive presumptive tube or P-A bottle
vigorously and transfer the growth with a sterile
3-mm loop or sterile applicator stick into
brilliant green
lactose
bile
broth
and
EC
medium,
defined below, to determine the presence of total
and fecal coliforms, respectively.
2)
For Microbiological Methods, referenced above,
whiohthat use a membranee filter, transfer the
total coliforni-positive culture by one of the
following methods:
remove the membrane containing
the
total
coliform
colonies
from
the
substrate
with
a
sterile
forceps
and carefully curl and
insert
the
membrane
into
a
tube
of
EC
medium.
(The
laboratory
may first remove a small portion
of
selected
colonies
for
verification);
swab
the
entire
membrane
filter
surface
with
a
sterile
cotton
swab
and
transfer
the
inoculum
to
EC
medium
(do
not
leave
the
cotton
swab
in
the
EC
medium);
or
inoculate
individual
total
coliform-positive
colonies
into
EC
medium.
Gently
shake
the
inoculated ~—tubes
of EC medium to insure
adequate mixing and incubate in a waterbath at
44.5
-t-/-
~0.2degrceo~.C for 24
1-/-
~2 hours.
Gas
production of any amount in the inner fermentation
tube of the EC medium indicates a positive fecal
coliform test.
3)
The preparation of EC medium is described in
Standard Methods,
16th Edition,j
Method 908C.
4)
Suppliers need only determine the presence or
absence of fecal coliforms,
a determination of
fecal coliform density is not required.
~
Suppliers shall conduct analysis of
E. coli in
accordance with one of the following analytical
methods:
fl..
EC medium supplemented with 50
Lia/L of
MUG
(final
concentration).
EC medium is as described in
subsection

At least
10
mL
of
EC
medium
su~~lemented with
MUG
must be
used.
The
inner
inverted

date that filtration is required.
The requirements
i
this
Section apply to filtered PWSs until June 29,
1993.
e
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 ahall~yreduce the
required sampling frequency. The option of
reducing the 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)

Averaging
Compliance with the MCLs of Sections 611.300 or 611.301

appropriate) must be determined based on the analytical result(s)
obtained at each sampling point.
~j
For suppliers that monitor at a frequency greater than
annual, compliance with the MCLs for asbestos, barium.
cadmium. chromium, fluoride, mercury, and selenium is
determined by a running annual average at each sampling
point.

If the average at any sampling point is greater
than the MCL.
then
the supplier is out of
compliance.

If any one sam~1ewould cause the annual average
to be exceeded, then the supplier is out of
compliance immediately.

be calculated at zero for the ~ur~ose of
determining the annual average.
BOARD
NOTE:
The “method detection limit”
is
different from the “detection limit”, as set forth
in_Section 611.600.
The “method detection limit”
is the level of contaminant that can be determined

in 40 CFR 136. appendix B, incorporated by
reference at Section 611.102.

determination
of
compliance will be based on the average of the two

Compliance with the I4CLs for nitrate and nitrite is
determined based on one sample if the levels of these
contaminants are below the MCL5.
If the levels of
nitrate or nitrite exceed the MCL5 in the initial
sample. Section 611.606 requires confirmation sampling,
and compliance is determined based on the average of
the_initial and confirmation samples.

The
use of the term “detect” in this section is not
intended to include any analytical capability of
~antifying
lower levels of any contaminant, or
the “method detection limit”.
Note. however that
certain lan~ua~eat the end of federal para~raph

1991.
e)
If the results exceed the MCL, the
CWS
or NTCW&NTNcW~
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-
trichioroethane, cis—1,2-dichioroethylene, trans-i, 2-
dichloroethylene 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
sample locations whichthat 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 VOC hated
in &eotion 611.3llof the Phase
I VOC5 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 VOCothe Phase
I
VOC5.
Reanalysis must be accomplished within fourteen
days of the second sample.
To composite samples, the
following procedure must be followed:

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 4dcgrccs~.C
during this step to minimize volatilization
losses.
C)
Mix well and draw out a 5-ml ahiquot for
analysis.
0)
Follow sample introduction, purging and
desorption steps described in the method.
E)
If less than five samples are used for

notlf
none
of
the
Phase
I
VOCs
are detected in the first sample
(or any
subsequent samples that may be taken and the
CWS

to one sample and must be repeated every
5
years.
B)
When
VOCo arc riotlf none of the Phase
I VOCs
are detected in the first sample
(or any
subsequent
sample
that
may
be
taken)
and
the
CWS
is vulnerable as defined in subsection
(h) (4)
U
37-31452
117
i)
Monitoring one sample must be repeated
every
3 years for CW~swith more than
500
connections.
ii)
Monitoring one sample must be repeated
every
5 years for CWSS with leso
than
500 or fewer connections.
C)
If VOCa arelf one of the Phase
I VOC5 is
detected in the first sample
(or any
subsequent sample that may be taken)
regardless
of
vulnerability,
monitoring
must
be repeated every
3 months,
as required under
subsection
(a).
2)
The repeat monitoring frequency for SWSs and mixed
systems
is as follows:
A)
When
VOCa arc notlf none of the Phase
I VOCs
j~detected in the first year of quarterly
sampling
(or any other subsequent sample that
may be taken) and the CWS is not vulnerable
as
defined
in
subsection
(h) (4),
additional
monitoring is not required.
B)
When
VOCo
arc notlf none of the Phase
I VOCs
j~.detected in the first year of quarterly
sampling
(or any other subsequent sample that
may be taken)
and the
CWS
is vulnerable as
defined
in
subsection
(h) (4):
i)
Monitoring must be repeated every three
years
(for CWS with more than 500
connections).
ii)
Monitoring must be repeated every five
years
(for CWS with lcoa than 500
.~
fewer connections).
C)
When VOCo arclf one of the Phase
I VOC5 is
detected in the first year of quarterly
sampling ~(orany other subsequent sample that
may be taken), regardless of vulnerability,
monitoring must be repeated every
3 months,
as required under subsection
(b).
3)
The Agency shall, by special exception
p~crmit~,
reduce the frequency of monitoring to once per
year for a GWS or SWS detecting VOCawhich detects
one of the Phase
I VOC5 at levels consistently
less than the MCL for three consecutive years,
unless the levels are increasing.
0137-01453
118
4)
The Agency shall, by special. oxooption permit~,
determine the vulnerability of each
CWS
based upon
an
assessment
of
the
following
factors:
A)
Previous monitoring results.
B)
Number of persons served by
CWS.
C)
Proximity of a smaller
CWS
to a larger CWS.
0)
Proximity to commercial or industrial use,
disposal or storage of the VOCo hated
in
Section 611.3llthe Phase
I VOCs.
E)
Protection of the water source.
5)
A CWs is deemed to be vulnerable for a period of
three years after any positive measurement of one
or more contaminants listed in Sections
611.650(e),
611.657(d)
or
611.311(a),
except for
THMs
or other demonstrated disinfection by-
products.
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 NT~jCWS
is deemed to be out of compliance.
If a
CWS
or NT~CWS
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, byapecial exception
pcrmitS~,
reduce the public notice requirement to that
portion
of
the
CWS
whichthat
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 no VOCanone of the
Phase
I VOCs were detected,
compliance is based on that
one sample.

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.
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 rng/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
0137-01476
141
fluoride.
Families with children under the age of nine
are encouraged to seek other sources of drinking water
for their children to avoid the pos3ibility 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 coéts.
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.

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
and any associated headaches and fatigue.
These
symptoms, however, are not just associated with
disease—causing organisms in drinking water, but also
may be cuascdcaused 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 coliforins
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
ocntaminatedcoritaminated 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
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
ocntaminatedcontaminated 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.

Nitrate.
The United States Environmental Protection
~gency
(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 sewaae 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 oxvaen carrying capacity of the
child’s blood.
This is an acute disease in that
svm~tomscan deve1o~rapidly in infants.
In most
cases.. health deteriorates over a period of days.
Symptoms include shortness of breath and blueness of

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 lona 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

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 cont~minants. 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
in-lury.
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
