Test Results <br />We are pleased to report that your drinking water meets or exceeds all federal and state requirements. Our water is monitored for <br />many different kinds of substances on a very strict sampling schedule, and the water we deliver must meet specific health standards. <br />Here, we only show those substances that were detected in our water (a complete list of all our analytical results is available upon request). <br />Remember that detecting a substance does not mean the water is unsafe to drink; our goal is to keep all detects below their respective <br />maximum allowed levels. <br />The state recommends monitoring for certain substances less than once per year because the concentrations of these substances do not <br />change frequently. In these cases, the most recent sample data is included, along with the year in which the sample was taken. <br />REGULATED SUBSTANCES <br />SUBSTANCE <br />(UNIT OF MEASURE) <br />YEAR <br />SAMPLED <br />MCL <br />[MRDL] <br />MCLG <br />[MRDLG] <br />AMOUNT <br />DETECTED RANGE <br />LOW-HIGH VIOLATION TYPICAL SOURCE <br />Barium (ppm)2024 2 2 0.03 NA No Discharge of drilling wastes; Discharge from <br />metal refineries; Erosion of natural deposits <br />Chlorine (ppm)2024 [4][4]0.72 0.54–0.91 No Water additive used to control microbes <br />Fluoride (ppm)2024 4 4 0.71 0.65–0.73 No Erosion of natural deposits; Water additive <br />which promotes strong teeth; Discharge from <br />fertilizer and aluminum factories <br />Gross Alpha Particle <br />Activity (pCi/L) <br />2020 15.4 0 3.6 ND–3.6 No Erosion of natural deposits <br />Haloacetic Acids [HAAs] <br />(ppb) <br />2024 60 NA 8.3 4.40–8.30 No By-product of drinking water disinfection <br />Nitrate (ppm)2024 10 10 1.30 ND–1.30 No Runoff from fertilizer use; Leaching from septic <br />tanks, sewage; Erosion of natural deposits <br />TTHMs [total <br />trihalomethanes] (ppb) <br />2024 80 NA 16.3 12.50–16.30 No By-product of drinking water disinfection <br />Xylenes (ppm)2023 10 10 ND NA No Discharge from petroleum factories; Discharge <br />from chemical factories <br />Tap water samples were collected for lead and copper analyses from sample sites throughout the community <br />SUBSTANCE <br />(UNIT OF MEASURE) <br />YEAR <br />SAMPLED AL MCLG <br />AMOUNT DETECTED <br />(90TH %ILE) <br />RANGE <br />LOW-HIGH <br />SITES ABOVE <br />AL/TOTAL SITES VIOLATION TYPICAL SOURCE <br />Copper (ppm)2022 1.3 1.3 0.23 NA 1/30 No Corrosion of household plumbing systems; <br />Erosion of natural deposits <br />Lead (ppb)2022 15 0 1.37 NA 0/30 No Lead service lines; Corrosion of household <br />plumbing systems, including fittings and <br />fixtures; Erosion of natural deposits <br />UNREGULATED SUBSTANCES <br />SUBSTANCE <br />(UNIT OF MEASURE) <br />YEAR <br />SAMPLED <br />AMOUNT <br />DETECTED <br />RANGE <br />LOW-HIGH TYPICAL SOURCE <br />Perfluorobutanoic Acid [PFBA] (ppt)2024 ND ND NA <br />Sodium1 (ppm)2024 3.32 3.16–3.32 NA <br />Sulfate (ppm)2024 8.34 2.89–8.34 NA <br />1 In-home water softening can <br />increase the level of sodium in <br />your water. <br />Definitions <br />90th %ile: The levels reported for lead <br />and copper represent the 90th percentile of <br />the total number of sites tested. The 90th <br />percentile is equal to or greater than 90% of <br />our lead and copper detections. <br />AL (Action Level): The concentration of <br />a contaminant which, if exceeded, triggers <br />treatment or other requirements which a <br />water system must follow. <br />MCL (Maximum Contaminant Level): <br />The highest level of a contaminant that is <br />allowed in drinking water. MCLs are set as <br />close to the MCLGs as feasible using the <br />best available treatment technology. <br />MCLG (Maximum Contaminant Level <br />Goal): The level of a contaminant in <br />drinking water below which there is no <br />known or expected risk to health. MCLGs <br />allow for a margin of safety. <br />MRDL (Maximum Residual Disinfectant <br />Level): The highest level of a disinfectant <br />allowed in drinking water. There is <br />convincing evidence that addition of a <br />disinfectant is necessary for control of <br />microbial contaminants. <br />MRDLG (Maximum Residual <br />Disinfectant Level Goal): The level of a <br />drinking water disinfectant below which <br />there is no known or expected risk to <br />health. MRDLGs do not reflect the benefits <br />of the use of disinfectants to control <br />microbial contaminants. <br />NA: Not applicable. <br />ND (Not detected): Indicates that the <br />substance was not found by laboratory <br />analysis. <br />pCi/L (picocuries per liter): A measure of <br />radioactivity. <br />ppb (parts per billion): One part substance <br />per billion parts water (or micrograms per <br />liter). <br />ppm (parts per million): One part <br />substance per million parts water (or <br />milligrams per liter). <br />ppt (parts per trillion): One part substance <br />per trillion parts water (or nanograms per <br />liter). <br />173
