<br />Copper (ppm) 5 <br />(07/03/13) <br /> <br />:En order to ensure that tap water is safe to drink, the USEPA and the State Water Resources Control Board (State <br />Board) prescribe regulations that limit the amount of certain contaminants in 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 the 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 necessarily 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 do not change frequently. Some of the data, though representative <br />of the water quality, are more than one year old. <br />TABLE 1 - SAMPLING RESULTS SHOWING THE DETECTION OF COLIFORM BACTERIA <br />MCLG Typical Source of Bacteria <br />Naturally present in the <br />0 environment <br /> <br />Microbiological <br />Contaminants <br />Highest <br />No. of Detections <br />No. of Months in Violation <br />MCL <br />Total Coliform <br />Bacteria <br />(In a mo.) <br />5* 1 <br />More than 1 sample in a month with a detection <br />0 <br />(In the <br />year) <br />A routine sample and a repeat sample detect total coliform and either sample also detects fecal colifonn or E. coil <br />Fecal Conform or <br />E. colt 0 Human and animal fecal waste <br />, <br />*Any violation of an MCL 07' AL is asterisked.

Conform Bacteria was detected in the drinking water distribution system. Colifonns are <br />bacteria that are naturally present in the environment an.d are used as an indicator that other, potentially-hannful, <br />bacteria may be present. Conforms 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 TH-Ie Jun 22 2015 9:22AM No.9017 SWS CCP. Form -Revised April 2000
