Microbiological Contaminants:
(2) Turbidity. Turbidity has no health effects. However, turbidity can interfere with disinfection and provide a medium for microbial growth. Turbidity may indicate the presence of disease-causing organisms. These organisms include bacteria, viruses, and parasites that can cause symptoms such as nausea, cramps, diarrhea, and associated headaches.
 (3) Copper. Copper is an essential nutrient, but some people who drink water-containing copper in excess of the action level over a relatively short amount of time could experience gastrointestinal distress. Some people who drink water-containing copper in excess of the action level over many years could suffer liver or kidney damage. People with Wilson's Disease should consult their personal doctor.

(4) Lead. Infants and children who drink water-containing lead in excess of the action level could experience delays in their physical or mental development. Children could show slight deficits in attention span and learning abilities. Adults who drink this water over many years could develop kidney problems or high blood pressure.

We constantly monitor for various constituent in the water supply to meet all regulatory requirements.

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 1-800-426-4791.

The sources of drinking water include river, lakes, streams, ponds, reservoirs, springs and wells.  As water travels over the surface of the land or through the ground, it can dissolve naturally -occurring minerals and, in some cases, radioactive materials.  The water can also pick up substances such as: 

(1)           Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural operations and wildlife.

(2)           Inorganic contaminants, such as salts and metals, which can be naturally-occurring in or result from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining or farming.

(3)           Pesticides and herbicides, which may come from agriculture, urban storm water runoff, and residential uses.

(4)           Organic chemical contaminants, which can come from industrial processes, gas stations, urban storm water runoff and septic systems.

(5)           Radioactive contaminants, which can be naturally occurring or the result of oil and gas production and mining activities.

In order to ensure that tap water is safe to drink, EPA establishes regulation, which limit the amount of certain contaminants in water provided by public water systems.  The Food and Drug Administration establishes limits for contaminants in bottled water.

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.

In our continuing efforts to maintain a safe and dependable water supply it may be necessary to make improvements in your water system. The costs of these improvements may be reflected in the rate structure. Rate adjustments may be necessary in order to address these improvements.

Thank you for allowing us to continue providing your family with clean, quality water this year. In order to maintain a safe and dependable water supply we sometimes need to make improvements that will benefit all of our customers. These improvements are sometimes reflected as rate structure adjustments. Thank you for understanding.

Some people may be more vulnerable to contaminants in drinking water than the general population. Immune-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).

Please call our office if you have questions.
We at Dayton Water Treatment Plant are constantly working to provide top quality water to every tap, said Johann K. Nield, Director of Public Works for the Town of Dayton.  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.

For a complete listing of the constituents for which we test and the results contact Johann K. Nield at 119 West 3rd Street, Dayton Wyoming, which is the address for the utilities building.  I will also answer any questions you may have concerning our water.
