In orde"r to ensure that tap water is safe to drink, the USEPA. and the State Nater Resources Control Board (State <br />Board) prescribe regulations that limit the amount. of certain contaminants ix1 water provided by public water systems. <br />State Board regulations also establish limits for contaminants in bottled water that must provide the same protection <br />for public health. <br />Tables 1., 2, 3, and 4 list all of tate drinking water contaminants that were detected during the most recent _ <br />sampling for the constituent. The presence of these contaminants in the water does not rxecessaffly indicate that the <br />water poses a health risk,. The State Board allows us to monitor for certain contaminants .less than once per year <br />because the concentrations of these contaminants donot change frequently. Some of the data, though representative <br />of the water quality, are more than one year old. <br />TABLE I - SAMPLING RESULTS SHOWING THE DETECTION OF COLIFORM BACTERIA <br />Microbiological <br />Contaminants <br />Total Coliform. <br />Highest <br />No. of <br />Detections <br />(In a mo.) <br />No. of <br />Min hs <br />Violation <br />1 <br />MCL <br />More than 1 <br />sample in a month <br />MCLG <br />0 <br />Bacteria <br />with a detection <br />routine sainp e <br />(Iia the <br />and a re eat <br />sample detect total <br />l~ ecal Coliform or <br />year) <br />0 <br />coliform and either <br />0 <br />L. coli <br />sample also detects. <br />0 <br />fecal calz£ozor <br />�m <br />.� cult <br />Typical Source of Bacteria <br />Naturally present in the <br />environment <br />Human and animal fecal waste <br />TABLE 2 - SAMPLING RESULTS SHOWING THE DETECTION OF LEAD AND COPPER <br />Sam. of Ifs PercentileqOt�l x .Sim -- -- ... .....,..._.....-- --- <br />tes <br />Lead and Copper PercentileP cal Source of <br />(and reporting units) Collected Level AL g AL PHG Contaminant <br />Detected <br />5 ' <br />Lead (ppb) < 5 0 15 0.2 <br />(07103113) <br />Capper (Ppm) <br />Any violation of an <br />5 <br />< 0.05 0 <br />(07103113) <br />L or A.L it aslerisked.

Coliforms were found in. more samples than. allowed and this was a warning of potential <br />problems. In response, the public was notified, and the entire drinking water system was disinfected, flushed, and re- <br />tested. Follow-up testing confirmed that the problem had been resolved. <br />Received T m e Jun , 2 2, 2015 9: 2 2 A M N o, 9 U 17 SWS CCP Form -Revised Apr112000 <br />
