Pesticides and herbicides: chemicals that may come from agriculture, urban storm water runoff, and residential uses. Microbial contaminants: viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife. Organic chemical contaminants: by- products of industrial processes and petroleum production, and can also come from gas stations, urban storm water runoff, and septic systems. Radioactive contaminants: naturally- occurring or the result of oil and gas production and mining activities. Drinking Water Regulations AL (Action Level): The concentration of a contaminant which, when exceeded, triggers treatment or other requirements. MCL (Maximum Contaminant Level): The highest level of a contaminant allowed in drinking water. MCLG (Maximum Contaminant Level Goal): The level of a contaminant in drinking water below which there is no known or expected risk to health. MRDL (Maximum Residual Disinfectant Level): The highest level of a disinfectant allowed in drinking water. (Maximum Residual Disinfection Level Goal): The level of a drinking water disinfectant below which there is no known or expected risk to health. Units of Measurement Parts per billion (ppb): One part per billion corresponds to one minute in 2,000 years Parts per million (ppm): One part per million corresponds to one penny in $10,000 Picocuries per Liter (pCi/L): a measurement of radioactivity per liter of water Micrograms per Liter (ug/L): a measurement of a substance per liter of water More information about contaminants and potential health effects can be obtained by reaching the EPA’s Safe Drinking Water Hotline at 1-[PHONE REDACTED] or www.epa.gov/safewater/hotline/ The City of Eagle routinely monitors for contaminants in your drinking water in accordance with federal and state regulations. At low levels, these substances are generally not harmful in our drinking water. The following table reflects your drinking water quality for the period of January 1, 2020 through December 31, 2020. DISINFECTANTS & DISINFECTION BY-PRODUCTS RADIOACTIVE CONTAMINANTS ---PAGE BREAK--- As water travels through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity. 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. The City of Eagle supplies drinking water from two groundwater wells: Well #1 Lexington Hills, and Well #3 Brookwood. After collection, your water is treated by disinfection, which involves the addition of chlorine to kill dangerous bacteria that may be in the water. Ken Acuff, Water Superintendent [PHONE REDACTED] [EMAIL REDACTED] Lead Information Elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily associated with service lines and home plumbing. We cannot control the variety of materials used in plumbing components. You can minimize the potential for lead exposure by flushing your tap for up to 2 minutes before using water. If you are concerned, you may wish to have your water tested. Reduce Your Water Bill! 6 Easy Ways to Conserve Water • Take short showers - a 5 minute shower uses 4 to 5 gallons of water versus 50 gallons for a bath. • Shut off water while brushing your teeth and shaving to save up to 500 gallons a month. • Use a water-efficient showerhead to save up to 750 gallons a month. • Run your clothes washer and dish- washer only when they are full to save up to 1,000 gallons a month. • Fixing or replacing leaky toilets and faucets can save up to 1,000 gallons a month. • Adjust sprinklers so only your lawn is watered. Apply water during the cooler parts of the day to reduce evaporation. Arsenic Information EPA continues to research the health effects of low levels of arsenic. Some people who drink water containing arsenic in excess of the MCL over many years could experience skin damage or problems with their circulatory system and may have an increased risk of cancer. Some people may be more vulnerable to contaminants in drinking water than the general population. These individuals can include: • persons undergoing chemotherapy • persons who have undergone organ transplants • people with HIV/AIDS or other immune system disorders • elderly individuals • infants and young children These individuals should consider seeking advice from a health care professional. Where Does My Drinking Water Come From? Exceedance of Maximum Contaminant Level Certain minerals are radioactive and may emit a form of radiation known as alpha radiation. Some people who drink water containing alpha emitters in excess of the MCL over several years may have an increased risk of cancer. We detected an exceedance of alpha emitters in September of 2019 in Well We will continue to monitor the levels of this contaminant. ---PAGE BREAK--- CONTAMINANT TABLE INORGANIC CONTAMINANTS Arsenic (ppb) N 0 10 2.9 3.3 2019 Erosion of natural deposits; runoff from glass/electronics production, orchards Barium (ppm) N 2 2 0 0.05 2019 Discharge of drilling wastes, metal refineries; Erosion of natural deposits Copper (ppm) N 1.3 1.3 (AL) NA 0.060 2018 Corrosion of household; Erosion of natural deposits Fluoride (ppm) N 4 4 0.33 0.33 2019 Erosion of natural deposits; Water additive to promote strong teeth; Erosion of natural deposits Uranium (ug/L) N 0 30 2 3 2020 Erosion of natural deposits Chlorine (ppm) N 4 4 0.360 1.08 2020 Water additive used to control microbes.
