Our system had no violations.
We’re proud that your drinking water meets or exceeds all Federal and
State requirements. We have learned through our monitoring and testing
that some constituents have been detected. The EPA has determined that
your water IS SAFE at these levels.
All sources of drinking water are subject to
potential contamination by constituents that are naturally occurring or
are man made. Those constituents can be microbes, organic or inorganic
chemicals, or radioactive materials.
All drinking water, including bottled water,
may reasonably be expected to contain at least small amounts of some
contaminants. The presence of contaminants does not necessarily indicate
that the water poses a health risk. More information about contaminants
and potential health effects can be obtained by calling the Environmental
Protection Agency’s Safe Drinking Water Hotline at 1-800-426-4791.
MCL’s are set at very stringent levels. To
understand the possible health effects described for many regulated
constituents, a person would have to drink 2 liters of water every day at
the MCL level for a lifetime to have a one-in-a-million chance of having
the described health effect.
Some
people may be more vulnerable to contaminants in drinking water than the
general population. Immuno-compromised persons such as persons with cancer
undergoing chemotherapy, persons who have undergone organ transplants,
people with HIV/AIDS or other immune system disorders, some elderly, and
infants can be particularly at risk from infections. These people should
seek advice about drinking water from their health care providers. EPA/CDC
guidelines on appropriate means to lessen the risk of infection by
cryptosporidium and other microbiological contaminants are available from
the Safe Drinking Water Hotline (800-426-4791).
We ask
that all our customers help us protect our water sources, which are the
heart of our community, our way of life and our children’s future.
