Frederick County Sanitation Authority

Frederick Water is supplied simply by quarries in Stephens City and Clearbrook. The water taken from these types of quarries is cured at the James They would. Diehl Water Filtering Plant and the Wayne T. Anderson Drinking water Filtration Plant. The filtration process includes chemical addition, flocculation, sedimentation, filtration to get rid of turbidity, and chlorination to disinfect this particular. Additional water is purchased from the Associated with Winchester. The City’s water is sucked from the North Shell of the Shenandoah Riv, a surface drinking water source. The seas from these 3 sources are combined in Frederick Water’s system and allocated to our customers. Through source water tests, VDH has decided that Frederick Water’s water sources might be susceptible to contamination as they are surface water resources exposed to a wide array of pollution at varying concentrations. Changing hydrologic, hydraulic and atmospheric circumstances promote migration of contaminants from area use activities of interest within the assessment place. Testing Your Normal water During 2017, Frederick Water’s laboratories on the Diehl and Anderson Water Filtration Plantlife ran more than 40, 000 process assessments to ensure your liquids meet the Va Department of Health insurance and the United States Environmental Protection Agency (EPA) specifications. Water Quality The water is consistently monitored according to Federal and Condition Regulations for several components. Tables one particular through 4 sums it up the results of your monitoring for the time between January one particular and December thirty-one, 2017 unless or else noted. The summaries below include just contaminants that were found at some level. Additional components were examined, but were not present or were under the detection limits in the lab equipment. The next definitions may be beneficial as you review the 2017 water top quality information: Definitions • Action Level (AL): The concentration of your contaminant, which, if exceeded, triggers a therapy or other necessity that a water program must follow. 2 • Maximum Contaminant Level (MCL): the highest amount of contaminant that is allowed in drinking water. MCLs are set because close to the MCLGs as possible using the best-offered treatment technology. • Maximum Contaminant Level Goal (MCLG): The amount of a contaminant in drinking water below which usually there is no known or perhaps expected risk to health. MGLGs permit a margin of safety. • Optimum Residual Disinfectant Level (MRDL): The highest standard of a disinfectant allowed in drinking water. There is certainly convincing evidence that the addition of a medical disinfectant is necessary for power over microbial contaminants. • Maximum Residual Medical disinfectant Level Goal (MRDLG): The level of a water disinfectant below which in turn there is no known or perhaps expected risk to health. MRDLG’s usually do not reflect the benefits of the usage of disinfectants to control microbes contaminants. • mrem/year - Millirems annually. A measure of rays absorbed by the physique. • - Certainly not Applicable. • ND: Non-detect. Concentration amounts so low these were not detectable. • NTU: Nephelometric Turbidity Unit (a way of measuring the clarity of water). • PCI/L - Picocuries every litre. • ppb: Parts per million - One portion per billion compares to 1 drop found in 15, 750 gallons. • ppm: Parts per million -- One part every million corresponds to one particular drop in sixteen gallons. • TT -Treatment Technique -- A required method intended to reduce the higher level contaminant in water..
