Information about your Drinking Water  The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the: surface of the land or through the ground, it dissolves naturaly-occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or 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 water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the EPAS Safe Drinking Water  from human activity.  Hotline at (800) 426-4791.  Contaminants that may! be present in source wateri include:  Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septics systems, agricultural livestock operations, and wildlife. inorganic contaminants, such as salts and metals, which can be naturally-occurring or result from urban storm water runoff, industrial or domestic wastewater discharges,  and gas production, mining, or farming.  Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban storm water runoff, and residential uses.  Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can also  from gas stations, urban storm water runoff, and septic systems.  Radioactive contaminants, which can be naturally-occurring or be the result of oil and gas production and mining activities. regulations establish limits for contaminants in bottled water which must provide the same protection for public health. information on taste, odor, or color of drinking water, please contact the: system's business office.  In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. FDA Contaminants may bei found in drinking water that may cause taste, color, or odor problems. These types of problems are not necessarily causes for health concerns. For more Your may be more vuinerable than the general population to certain microbial contaminants, such as Cryptosporidium, in drinking water. Infants, some elderly, or mmunocompromised persons such as those undergoing chemotherapy for cancer; persons who have undergone organ transplants; those who are undergoing treatment with steroids; and people with HIV/AIDS or other immune system disorders, can be particularly at risk from infections. Yous should seek advice about drinking water from your physician or health care providers. Additional guidelines on appropriate means to lessen the risk ofi infection by Cryptosporidium are available from the. Safe Drinking' Water 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 components associated with: service lines and home plumbing. We: are responsible for providing high quality drinking water, but we cannot control the variety of materials us in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tapi for 30: seconds to 2 minu before using water for drinking or cooking. Ify you: are concerned about leadi iny your water, you may wisht tol have your water tested. Information on lead in drinking water, te methods, and steps you can take to minimize exposure is available from the Safe Drinking' Water Hotline or at httpy/www.epagov/salewater/lead.
