                Public Notification (PN) Rule, 65 FR 25982, May 4, 2000.
                To notify the public of drinking water violations or situations that may pose a risk to public
                health.
                The PN Rule requires all public water systems (PWSs) to notify their consumers any time a
                PWS violates a national primary drinking water regulation or has a situation posing a risk to
                public health. Notices must be provided to persons served (not just billing customers).
                All PWSs.
                Notices must be sent within 24 hours, 30 days, or one year depending on the tier to which the
                violation is assigned. The clock for notification starts when the PWS learns of the violation.
                                  Tier 1 (Immediate Notice, Within 24 Hours)
                                  Tier 1 PN is required to be issued as soon as practical but no later than 24 hours after the PWS learns of the
                                  violation or situation including:
                                  >   Distribution system sample violation when fecal coliform or E. coli are present; failure to test for fecal
                                      coliform or E. coli after initial total coliform distribution system sample tests positive.
                                  ^   Nitrate, nitrite, or total nitrate and nitrite maximum contaminant level (MCL) violation; failure to take
                                      confirmation sample.
                                  >   Special notice for noncommunity water systems (NCWSs) with nitrate exceedances between 10 mg/L and
                                      20 mg/L, where system is allowed to exceed 10 mg/L by primacy agency.
                                  ^   Chlorine dioxide maximum residual disinfectant level (MRDL) violation when one or more of the samples
                                      taken in the distribution system exceeds the MRDL on the day after a chlorine dioxide measurement taken
                                      at the entrance to the distribution system exceeds the MRDL, or when required samples are not taken in the
                                      distribution system.
                                  >   Exceedance of maximum allowable turbidity level, if elevated to a Tier 1  notice by primacy agency.
                                  ^   Waterborne disease outbreak or other waterborne emergency.
                                  ^   Detection of E. coli, enterococci, or coliphage in a ground water source sample.
                                  >   Other violations or situations determined by the primacy agency.
 Tier 2 PN is required to be issued as soon as practical or within 30 days. Repeat notice every 3 months until
 violation or situation is resolved.
 ^  All MCL, MRDL, and treatment technique violations, except where Tier 1 notice is required.
 ^  Monitoring violations, if elevated to Tier 2 notice by primacy agency.
 >  Failure to comply with variance and exemption conditions.
 >  For ground water systems providing 4-log treatment and conducting Ground Water Rule (GWR) compliance
     monitoring, failure to maintain required treatment for more than 4 hours.
 ^  Failure to take any required corrective action or be in compliance with a corrective action plan for a fecal
     indicator-positive ground water source sample.
 >  Failure to take any required corrective action or be in compliance with a corrective action plan for a
     significant deficiency under the GWR.
 ^  Special public notice for repeated failure to conduct monitoring for Cryptosporidium.
 Turbidity consultation is required when a PWS has a treatment technique violation resulting from a single
 exceedance of the maximum allowable turbidity limit or an MCL violation resulting from an exceedance of the
 2-day turbidity limit. The PWS must consult their primacy agency within 24 hours. Primacy agencies will then
 determine whether a Tier 1  PN is necessary. If consultation does not occur within 24 hours, violations are
 automatically elevated to require Tier 1 PN.
 Tier 3  (Annual Notice)
 Tier 3 PN is required to be issued within 12 months and repeated annually for unresolved violations.
 >  All monitoring or testing procedure violations, unless primacy agency elevates to Tier 2, including failure
     to conduct benchmarking and profiling (surface water systems) and failure to develop a monitoring plan
     (disinfecting systems).
 >  Operating under a variance and exemption.
 >  Special public notice for availability of unregulated contaminant monitoring results.
 ^  Special public notice for fluoride secondary maximum contaminant level (SMCL) exceedance.

-------
Unless otherwise specified in the regulations,* each notice must contain:

    1.    Description of the violation or situation, including the contaminant(s) of concern, and (as applicable) the contaminant level(s).
    2.    When the violation or situation occurred (i.e., date the sample was collected or was supposed to be collected).
    3.    Any potential adverse health effects from drinking the water and standard language regarding the violation or situation. (For MCL, MRDL,
         treatment technique violations, or violations of the conditions of a variance or exemption, use health effects language from Appendix B of the
         PN Rule. For monitoring and testing procedure violations, use the standard monitoring language below.)
    4.    The population at risk, including subpopulations that may be particularly vulnerable if exposed to the contaminant in their drinking water.
    5.    Whether alternate water supplies should be used.
    6.    Actions consumers should take, including when they should seek medical help, if known.
    7.    What the PWS is doing to correct the violation or situation.
    8.    When the PWS expects to return to compliance or resolve the situation.
    9.    The name, business address, and phone number or those of a designee of the PWS as a source of additional information concerning the
         notice.
    10.  A statement (see standard distribution language below) encouraging notice recipients to distribute the notice to others, where applicable.
* These elements do not apply to notices for fluoride SMCL exceedances, availability of unregulated contaminant monitoring data, and operation under
a variance or exemption.  Content requirements for these notices are specified in the PN Rule.

Standard Language:
Standard Monitoring Language: We are required to monitor your drinking water for specific contaminants on  a regular basis.  Results of regular
monitoring are an indicator of whether or not our drinking water meets health standards. During [period] we [did not monitor or test/did not complete all
monitoring or testing] for [contaminant(s)],  and therefore cannot be sure of the quality of the drinking water during that time.

Standard Distribution Language:  Please share this information with all the other people who drink this water,  especially those who may not have
received this notice directly (for example, people in apartments,  nursing homes, schools, and businesses). You can do this by posting this notice in a
public place or distributing copies by hand  or mail.
Multilingual Requirements
    Where the PWS serves a large proportion of non-English speakers, the PWS must provide information in the appropriate language(s) on the
    importance of the notice or on how to get assistance or a translated copy.
>  The Tier 1 PN must be issued via radio, TV, hand delivery, posting, or other method specified by the primacy agency to reach all persons served.
    PWSs must also initiate consultation with the primacy agency within 24 hours. Primacy agency may establish additional requirements during
    consultation.
^  The Tier 2 and Tier 3 PNs must be issued by Community Water Systems (CWSs) via mail or direct delivery and by NCWSs via posting, direct
    delivery, or mail. Primacy agencies may permit alternate methods. All  PWSs must use additional delivery methods reasonably calculated to reach
    other consumers not notified by the first method.*
>  Notices for individual violations can be combined into an annual notice (including the Consumer Confidence Report [CCR], if PN requirements can
    still be met).
*  Each PN:
    >    Must be displayed in a conspicuous way.
    ^    Must not include overly technical language or very small print.
    ^    Must not be formatted  in a way that defeats the purpose of the notice.
    >    Must not include language that nullifies the purpose of the notice.
^  If the notice is posted, it must remain in place for as long as the violation or situation persists, but in no case for less than seven days, even if the
    violation or situation is resolved.
*PWSs should check with their primacy agency to determine the most appropriate delivery methods.
Notices  to  New  Customers
    All new billing units and customers must be notified of ongoing violations or situations requiring PN.
Reoortins? and  Recordkeeoin:
    PWSs have 10 days to send a certification of compliance and a copy of the completed notice to the primacy agency.
    PWS and primacy agency must keep notices on file for 3 years.

IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER
Tests Showed Presence of Coliform Bacteria
The Jonesville Water System routinely monitors for coliform bacteria. During
the month of July, 7 percent of our samples tested positive. The standard is that
no more than 5 percent of samples may test positive.
What should I do?
 You do not need to boil your water or take other corrective actions.
However, if you have specific health concerns, consult your doctor.
 You do not need to use an alternate (e.g., bottled) water supply.
People with severely compromised immune systems, infants, pregnant
women, and some elderly may be at increased risk. These people should
seek advice about drinking water from their health care providers. General
guidelines on ways to lessen the risk of infection by microbes are available
from EPA's Safe Drinking Water Hotline at 1-800-426-4791.
What does this mean?
This is not an emergency. If it had been, you would have been notified
immediately. Coliform bacteria are generally not harmful themselves. Conforms
are bacteria which are naturally present in the environment and are used as
an indicator that other, potentially-harmful, bacteria may be present. Conforms
were found in more samples than allowed and this was a warning of potential
problems.
Usually, coliforms are a sign that there could be a problem with the system's
treatment or distribution system (pipes). Whenever we detect coliform bacteria
in any sample, we do follow-up testing to see if other bacteria of greater
concern, such as fecal coliform or E. coli, are present. We did not find any of
these bacteria in our subsequent testing.
What was done?
We took additional samples for coliform bacteria which all came back negative.
As an added precaution, we chlorinated and flushed the pipes in the distribution
system to make sure bacteria were eliminated. This situation is now resolved.
For more information, or to learn more about protecting your drinking water
please contact John Jones at (502) 555-1212.
Please share this information with all the other people who drink this water,
especially those who may not have received this notice directly (for example,
people in apartments, nursing homes, schools, and businesses). You can do
this by posting this notice in a public place or distributing copies by hand or
mail.
This is being sent by the Jonesville Water System.
