Please note: The Consumer Confidence Report is amended to include the correct state defined potential sources of contamination. No contaminants have been detected. If any contaminants were detected in our water their sources may be from: chemical storage, wastewater discharge, mine sites, leaking storage tanks, oil/gas wells, roads, transportation, residential, farming, forests, and other facilities.
Lead in Drinking Water
If present, elevated levels of lead can cause health problems (especially for pregnant women and young children). It is possible that lead levels at your home may be higher than other homes in the community as a result of materials used in your home’s plumbing. If you are concerned about lead, you may wish to have your water tested. 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. Additional information on lead in drinking water is available from the Safe Drinking Water Hotline 1-800-426-4791 or at www.epa.gov/lead.
Terms and Abbreviations
Action Level (AL): The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
Maximum Contaminant Level (MCL): The ‘Maximum Allowed’ is the highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.
Maximum Contaminant Level Goal (MCLG): The ‘Goal’ is the level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.
Maximum Residual Disinfectant Level (MRDL): Highest level of a disinfectant allowed in drinking water, based on convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.
Nephelometric Turbidity Unit (NTU): Nephelometric turbidity unit is a measure of the clarity of water. Turbidity in excess of 5 NTU is just noticeable to the average person.
Parts per million (ppm): One part per million corresponds to 1 milligram per liter (mg/l), a very dilute concentration of substance.
Parts per billion (ppb): One part per billion corresponds to 1 microgram per liter (µg/l), a very dilute concentration of substance.
Treatment Technique (TT): A treatment technique is a required process intended to reduce the level of a contaminant in drinking water. Violation: Failure to meet a Colorado Primary Drinking Water Regulation.
