You may be more vulnerable than the general population to certain When drinking water meets federal standards there may not be any microbial contaminants,such as Cryptosporidium, in drinking water. health based benefits to purchasing bottled water or point of use Infants, some elderly or immunocompromised persons such as those devices. Drinking water, including bottled water, may reasonably be undergoing chemotherapy for cancer; undergone organ transplants; expected to contain at least small amounts of some contaminants.The undergoing treatment with steroids; and people with HIV/AIDS or other presence of contaminants does not necessarily indicate that the water immune system disorders can be particularly at risk from infections.You poses a health risk. More information about contaminants and potential should seek advice about drinking water from your physician or health health effects can be obtained by calling the EPA Safe Water Hotline care provider.Additional guidelines on appropriate means to lessen the (800)426-4791. risk of infection by Cryptosporidium are available from the Safe Drinking Water Hotline at(800)426-4791. Secondary Constituents: Many constituents(such as calcium, sodium,or iron)which are often Public Participation Opportunities: found in drinking water can cause taste, color, and odor problems.The We encourage public interest and participation in our community's taste and odor constituents are called secondary constituents and are decisions affecting drinking water.

MCLs are set as close to the MCLGs as feasible using the best available treatment technology. Water Sources: Maximum Residual Disinfectant Level (MRDL): The highest Drinking water sources(both tap water and bottled water) include rivers, level of disinfectant allowed in drinking water.There is convincing evidence lakes, streams, ponds, reservoirs,springs and wells.As water travels that addition of a disinfectant is necessary for control of microbial over the surface of the land or through the ground, it dissolves contaminants. naturally-occurring minerals and in some cases, radioactive material, Maximum Residual Disinfectant Level Goal (MRDLG):The and can pick up substances resulting from the presence of animals or level of a drinking water disinfectant below which there is no known or from human activity. Contaminants that may be present in source water expected risk to health. MRDLGs do not reflect the benefits of the use of before treatment include: microbes, inorganic contaminants, pesticides, disinfectants to control microbial contamination. herbicides, radioactive contaminants&organic chemical contaminants.

Unregulated Contaminant Monitoring Rule 2(UCMR2) -Unregulated contaminants are those for which EPA has not established drinking water standards.The purpose of unregulated contaminant monitoring is to assist EPA in determining the occurrence of unregulated contaminants in drinking water and whether future regulation is warranted.Any unregulated contaminants detected are reported in the following table.For additional information and data visit http://www.epa. ov/safewater/ucmr/ucmr2/index.html,or call the Safe Drinkin Water Hotline at 800 426-4791. 2009 None detected N/A N/A N/A N/A N/A Lead and Copper-If present,elevated levels of lead can cause serious health problems,especially for pregnant women and young children.Lead in drinking water is primarily from materials and components associated with service lines and home plumbing.This water supply is responsible for providing high quality drinking water,but cannot control the variety of materials used in plumbing components.When your water has been sitting for several hours,you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking.If you are concerned about lead in your water,you may wish to have your water tested.Information on lead in drinkin.water,testin.methods and steps ou can take to minimize exposure is available from the Safe Drinkin.Water Hotline or at http://www.e.a..ov/safewater/lead.

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.arasites that can cause s m.toms such as nausea,crams,diarrhea and associated headaches.

Total Coliform-Total coliform bacteria are used as indicators of microbial contamination of drinking water because testing for them is easy.While not disease-causing organisms themselves,they are often found in association with other microbes that are capable of causing disease.Coliform bacteria are hardier than many disease-causing organisms;therefore,their absence from water is a good indication that the water is microbiologically safe for human consum.tion.
