Bacteriological and Chemical Monitoring <br /> Description of program (contract for sample collection): Far West <br /> Is the Bacti Sample Siting Plan current? Yes <br /> Violations in past year? General Order for PFOA/PFOS <br /> Any fecal (E. coli) positives? No <br /> Review of sample sites: <br /> <br />Title 22 of the California Code of Regulations requires routine monitoring of your water system by a State certified laboratory. Sampling <br />must be performed by State certified laboratory personnel or CDO/CTO. All samples shall be taken at the wellhead, except for <br />bacteriological and Lead and Copper sampling. Please be aware that all results for samples analyzed for a system in a calendar month <br />shall be reported to the EHD no later than the tenth day of the following month. The EHD strongly recommends the use of non-threaded, <br />dedicated sample taps for bacteriological sampling in the distribution system. <br />Bacteriological: Required quarterly/monthly for Total coliform bacteria. Instruct your laboratory to collect a Routine sample once each <br />quarter/month. If a Routine sample tests positive for coliform, instruct your laboratory to collect three/four Repeats samples within 24 <br />hours of being notified by your laboratory and to continue to collect repeat sample sets until all samples are negative. The report <br />should be with the results enumerated and chlorine residuals reported for all of these samples. Notify EHD, if more than one of the <br />samples is positive for total coliform, and within 24 hours if any samples are E. Coli positive. <br /> <br />Quarterly; due Q4 2021 Nitrates: Required quarterly/annually. <br />2024 Nitrites: Required once every three years. <br />2024 Inorganic Chemicals & Perchlorate: Required once every three years. EHD waived monitoring for asbestos <br />and cyanide. <br />2025 Volatile Organic Compounds (VOCs): Waived to once every six years. <br />EDB/DBCP: 2022 <br />TCP: 2021 <br />Atrazine/Simazine: 2021 <br />Synthetic Organic Compounds (SOCs): EHD waived monitoring for all SOCs, except for: <br />DBCP- Required once every year/three year(s) and EDB - Required once every year/ three years. <br />1,2,3-TCP - Required once every year/three years. <br />Atrazine: Waived to nine years. Simazine: Waived to nine years. <br />2022 Lead and Copper: Required once every six months/three years. A sample set of five/ten samples shall be <br />collected from the distribution system between the months of June through September, & six months later. <br />2025 Radiological: Gross Alpha/Radium 228: Required quarterly for one year. EHD waived Gross Alpha <br />monitoring to once every 1/3/6/9 year(s). <br />----------------------------- Secondary (Aesthetics): General Mineral and General Physical are due every three years. <br /> <br />Complies with all Primary MCLs? <br />Yes <br /> <br /> <br />2.
