Monthly Trends

During the fall of 2002, the Hotline noted an increase in questions about public
notification (PN) that were specifically associated with Total Coliform Rule (TCR)
violations. These questions were primarily posed by citizens with concerns about
the contents or timing of notifications they had received. Most of the notifications
described Tier 2 TCR violations that had occurred the month before they were
received, and many callers asked why their water systems had not notified them
sooner about those violations. Hotline Information Specialists explained to these
individuals that the PN rule generally requires notification within 30 days of a Tier
2 violation. The following graphs illustrate the increase in TCR related PN
questions, relative to total PN questions, over the last several months.

Frequently Asked Qs & As

This section provides answers to frequently asked
questions not necessarily represented in one of the
Top Ten Topic categories.

Q: Our water quality has been terrible for days, but
the water company says that there is no problem
and will not provide any information more current
than the 2002 annual water quality report. With
whom can I speak about this situation?

A: Public water systems oversee the drinking water
delivered to your home. You should first contact
your drinking water provider. If you do not obtain a
satisfactory explanation, your next step should be
contacting your state drinking water program office,
which has the regulatory enforcement authority to
ensure water systems in the state are meeting all
drinking water standards. [State drinking water
program offices can be found at
www.epa.gov/safewater/dwinfo.htm.] Finally, the
Environmental Protection Agency may be able to
help. Please contact the Safe Drinking Water
Hotline if you need assistance in obtaining any
telephone numbers.

Q: I am concerned about the quality of my drinking
water, but I am afraid to ask the water company for
information. How can I find out if my water system is
in compliance and providing safe drinking water?

A: Under the Safe Drinking Water Act, most water
suppliers are required to provide their customers
with annual drinking water quality reports, or
consumer confidence reports (CCRs). These
reports tell consumers, among other things, what
contaminants have been detected in their drinking
water and how these detection levels compare to
national drinking water standards. The reports must
be provided annually before July 1, and, in most
instances, are mailed directly to customers' homes.
Your water system's CCR may be posted on-line at:
www.epa.gov/safewater/dwinfo.htm. Alternately, to
obtain a copy of your water system's most recent
CCR or additional information about the system, you
should contact your local water supplier directly. If
you have reason to believe that your water supplier
is not complying with federal drinking water
regulations, you may contact your state drinking
water program office.

Q: We are going to be changing our water system's
disinfection practice. Is there a public notification
requirement when a system switches from chlorine
to chloramines?

A: According to Tom Grubbs of EPA's OGWDW,
there is no formal notification requirement when a
system changes its disinfection practice, but there
are important reasons to do so when changing to
chloramines. Since kidney dialysis patients will be
affected, dialysis centers, hospitals, and other health
care providers must be notified. Chloramines must
be removed from water used for dialysis, and is
more difficult than chlorine removal. In addition,
because chloramines are toxic to fish, pet stores and
aquariums should be notified so that they can
remove any residual chloramines.

Q: Our water system is subject to the Stage 1
Disinfectants and Disinfection Byproducts (DBP)
Rule. What requirements must we meet to qualify
for reduced monitoring for disinfectant byproduct
precursors (DBPP)?

A: Subpart H systems with an average treated water
total organic carbon (TOC) of less than 2.0 mg/L for
two consecutive years, or less than 1.0 mg/L for one
year, may reduce monitoring for both TOC and
alkalinity to one paired sample and one source water
alkalinity sample per plant per quarter (40 CFR
141.132(d)(2)). The system must revert to routine
monitoring in the month following the quarter when
the annual average treated water TOC is greater
than or equal to 2.0 mg/L.

Q: When a public water system (PWS) monitors for
chlorine in the distribution system, should the
residual disinfectant be measured as free chlorine or
total chlorine?

A: A PWS must measure residual disinfectant
concentrations with one of the analytical methods
approved by EPA for this purpose (40 CFR
141.74(a)(2)). The table in 40 CFR 141.74(a)(2)
includes EPA approved analytical methods for
residual disinfectant based on both free chlorine and
total chlorine.

Q: Must a community water system distribute
consumer confidence reports (CCRs) to consumers
who are served by the system but are not bill-paying
customers (e.g., renters or workers)?

A: According to 40 CFR 141.155(b), a system must
make a good faith effort to distribute its CCR to
consumers who do not receive water bills, using
means recommended by the primacy agency. A
good faith effort to reach consumers would include a
mix of methods appropriate to the particular system,
such as posting the reports on the Internet, mailing
to postal patrons in metropolitan areas, advertising
the availability of the report in the news media,
publication in a local newspaper, posting in public
places such as cafeterias or lunch rooms of public
buildings, delivery of multiple copies for distribution
by single-biller customers such as apartment
buildings or large private employers, and delivery to
community organizations.

Q: l/l/e are preparing to do our Unregulated
Contaminant Monitoring Rule List 1 sampling. Is
there a time frame specified for samples to be
shipped to the laboratory for analysis?

A: Unless otherwise informed by the state or EPA of
other sampling arrangements, public water systems
monitoring for List 1 contaminants must collect
samples in a manner that allows adequate time for
the samples to be sent via overnight delivery to the
laboratory (40 CFR 141.40 (a)(5)®(A)). This is
because some samples must be processed within
30 hours of collection.

Q: Our state transportation department has plans to
move a natural spring that serves as a partial source
of drinking water for our community's well. To whom
can we address our concerns about this proposed
project?

A: If you have concerns about the potential impact
of an activity on your community's source water, you
may contact your state's Source Water Assessment
and Protection Program office. The source water
program offices for every state can be found at
www.epa.gov/safewater/dwinfo.htm.

Q: Is it possible to find out the number of Class II oil
and gas underground injection control (UIC) wells in
a particular state?

A: The approximate number of Class II oil and gas
UIC wells in each state is provided at
www.epa.gov/safewater/uic/classii.html. More
specific information, including the exact number of
Class II UIC wells in a state may be available from
the state's Underground Injection Control Program
contact. A list of these contacts is available at
www.epa.gov/safewater/uic/states.html.

Did You Know?

Tap water costs slightly over $2.00 per 1,000 gallons in the United States
(EPA 1999 report, Drinking Water Costs and Federal Funding).
