If you <br />would like to participate in the process, please contact the <br />Village/City Clerk to arrange to be placed on the agenda of the <br />meeting of the Village Board/City Council. <br />Drinking water, including bottled water, may reasonably be <br />expected to contain at least small amounts of some conta- <br />minants. The presence of contaminants does not necessarily <br />indicate that water poses a health risk. More information about <br />contaminants and potential health effects can be obtained by <br />calling the EPA's Safe Drinking Water Hotline (800-426-4791). <br />Source Water Assessment Availability: <br />The Nebraska Department of Environmental Quality (NDEQ) has <br />completed the Source Water Assessment. Included in the <br />assessment are a Wellhead Protection Area map, potential <br />contaminant source inventory, and source water protection <br />information. To view the Source Water Assessment or for more <br />information please contact the person named above on this <br />report or the NDEQ at (402) 471-3376 or go to http://deo.ne.gov. <br />In order to ensure that tap water is safe to drink, EPA prescribes <br />regulations which limit the amount of certain contaminants in <br />water provided by public water systems. FDA regulations <br />establish limits for contaminants in bottled water which must <br />provide the same protection for public health. <br />Sources of Drinking Water: <br />The sources of drinking water (both tap water and bottled water) <br />include rivers, lakes, streams, ponds, reservoirs, springs, and <br />groundwater wells. As water travels over the surface of the land <br />or through the ground, it dissolves naturally -occurring minerals <br />and, in some cases, radioactive material, and can pick up <br />substances resulting from the presence of animals or from <br />human activity. <br />The source of water used by City Of Blair is surface water. <br />Contaminants that may be present in source water include: <br />* Microbial contaminants, such as viruses and bacteria, which <br />may come from sewage treatment plants, septic systems, <br />agricultural livestock operations and wildlife. <br />* Inorganic contaminants, such as salts and metals, which can <br />be naturally occurring or result from urban storm water runoff, <br />industrial, or domestic wastewater discharges, oil and gas <br />production, mining, or farming. <br />* Pesticides and herbicides, which may come from a variety of <br />sources such as agriculture, urban storm water runoff, and <br />residential uses. <br />* Organic chemical contaminants, including synthetic and <br />volatile organic chemicals, which are by-products of industrial <br />processes and petroleum production, and can also come from <br />gas stations, urban storm water runoff, and septic systems. <br />* Radioactive contaminants, which can be naturally -occurring or <br />be the result of oil and gas production and mining activities. <br />Drinking Water Health Notes: <br />Some people may be more vulnerable to contaminants in <br />drinking water than the general population. Immunocompromised <br />persons such as persons with cancer undergoing chemotherapy, <br />persons who have undergone organ transplants, people with <br />HIV/AIDS or other immune system disorders, some elderly, and <br />infants can be particularly at risk from infections. These people <br />should seek advice about drinking water from their health care <br />providers. EPA/CDC guidelines on appropriate means to lessen <br />the risk of infection by Cryptosporidium and other, microbial <br />contaminants are available from the Safe Drinking Water Hotline <br />(800-426-4791) or the Department of Health and Human <br />Services, Division of Public Health, Office of Drinking Water at <br />402-471-2186. <br />If present, elevated levels of lead can cause serious health <br />problems, especially for pregnant women and young children. <br />Lead in drinking water is primarily from materials and <br />components associated with service lines and home plumbing. <br />All Community water systems are responsible for providing high <br />quality drinking water, but cannot control the variety of materials <br />used in plumbing components. When your water has been <br />sitting for several hours, you can minimize the potential for lead <br />exposure by flushing your tap for 30 seconds to 2 minutes before <br />using water for drinking or cooking. if you are concerned about <br />lead in your water, you may wish to have you water tested. <br />Information on lead in drinking water, testing methods, and steps <br />you can take to minimize exposure is available from the Safe <br />Drinking Water Hotline (800-426-4791), at <br />http://www.epa.gov/safewater/lead or at the DHHS/DPH/Office of <br />Drinking Water (402-471-1008). ' <br />The City Of Blair is required to test for the following contaminants: <br />Coliform Bacteria, Antimony, Arsenic, Asbestos, Barium, Beryllium, <br />Cadmium, Chromium, Copper, Cyanide, Fluoride, Lead, Mercury, Nickel, <br />Nitrate, Nitrite, Selenium, Sodium, Thallium, Alachlor, Atrazine, <br />Benzo(a)pyrene, Carbofuran, Chlordane, Dalapon, Di(2-ethylhexyl)adipate, <br />Dibromochloropropane, Dinoseb, Di(2-ethylhexyi)- phthalate, Diquat, 2,4- <br />D, Endothall, Endrin, Ethylene dibromide, Glyphosate, Heptachlor, <br />Heptachlorepoxide, Hexachlorobenzene, Hexachlorocyclopentadiene, <br />Lindane, Methoxychlor, Oxamyl (Vydate), Pentachlorophenol, Picloram, <br />Polychlodnated biphenyls, Simazine, Toxaphene, Dioxin, Silvex, Benzene, <br />Carbon Tetrachloride, o-Dichloro- benzene, Para -Dichlorobenzene, 1,2- <br />Dichlorethane, 1,1-Dichloroethylene, Cis-1,2,-Dichloroethylene, Trans-1,2- <br />Dichloroethylene, Dichloromethane, 1,2-Dichloropropane, Ethylbenzene, <br />Monochlorobenzene, 1,2,4-Tdchloro- benzene, 1,1,1 -Trichloroethane, <br />1,1,2 -Trichloroethane, Trichloroethylene, Vinyl Chloride, Styrene, <br />Tetrachloroethylene, Toluene, Xylenes (total), Gross Alpha (minus <br />Uranium & Radium 226), Radium 226 plus Radium 228, Sulfate, <br />Chloroform, Bromodichloromethane, Chlorodibromomethane, Bromofonn, <br />Chiorobenzene, m -Dichlorobenzene, 1,1-Dichloropropene,1,1- <br />Dichioroethane, 1,1,2,2-Tetrachlorethane, 1,2-Dichloropropane, <br />Chloromethane, Bromomethane, 1,2,3-Tdchloropropane, 1,1,1,2 -Tetra- <br />chloroethane, Chloroethane, 2,2-Dichloropropane, o-Chiorotoluene, p- <br />Chlorotoluene, Bromobenzene, 1,3-Dichloropropene, Aldrin, Butachlor, <br />Carbaryl, Dicamba, Dieldrin, 3-Hydroxycarbofuran, Methomyl, Metolachlor, <br />Metdbuzin, Propachlor. <br />How to Read the Water Quality Data Table: <br />The EPA and State Drinking Water Program establish the safe <br />drinking water regulations that limit the amount of contaminants <br />allowed in drinking water. The table shows the concentrations of <br />detected substances in comparison to the regulatory limits. <br />Substances not detected are not included in the table. The state <br />requires monitoring of certain contaminants less than once per year <br />because the concentrations of these contaminants do not change <br />frequently. Therefore, some of this data may be older than one year. <br />MCL (Maximum Contaminant Level) —The highest level of a conta- <br />minant that is allowed in drinking water. MCLS are setas close to the <br />MCLGs as feasible using the best available treatment technology. <br />MCLG (Maximum Contaminant Level Goal) —The level of a <br />contaminant in drinking water below which there is no known or <br />expected risk to health. MCLGs allow for a margin of safety. <br />AL (Action Level) —The concentration of a contaminant which, if <br />exceeded triggers treatment or other requirements which a water <br />system must follow. <br />MRDL (Maximum Residual Disinfectant Level) —The highest level <br />of a disinfectant allowed in drinking water. <br />NIA — Not applicable. <br />Units in the Table: <br />NO — Not detectable. <br />ppm (parts per million) — One ppm corresponds to 1 gallon of <br />concentrate In 1 million gallons of water. <br />mg/L (milligrams per liter) — Equivalent to ppm. <br />ppb (parts per billion) — One ppb corresponds to 1 gallon of concentrate <br />in 1 billion gallons of water. <br />ug/L (micrograms per liter) — Equivalent to ppb. <br />pCi/L (Picocuries per liter) — Radioactivity concentration unit. <br />RAA (Running Annual Average) —An ongoing annual average <br />calculation of data from the most recent four quarters. <br />LRAA (Locational Running Annual Average)—An ongoing annual <br />average calculation of data from the most recent four quarters at each <br />sampling location. <br />901" Percentile— Represents the highest value found out of 90% of the <br />samples taken in a representative group. If the 90th percentile is greater <br />than the action level, it will trigger a treatment or other requirements that a <br />water system must follow. <br />TT (Treatment Technique) —A required process intended to reduce the <br />level of a contaminant in drinking water. <br />
