The Muir Beach Community Services District is required by the Division of Drinking Water of the State Water Resources Control Board (DDW) to prepare and provide an annual Water Quality Report to Muir Beach residents and water users by June for the prior year of tests. Please see attached 2023 Water Quality Report which is written for even non-technical readers.
The Muir Beach water system is very stable and continues to deliver high quality and safe water to our small community. This past year we were able to maintain the minimum State required safe chlorine treatment residual level for a public water system of approximately .3-.4 as well as continuing a minimal level of silica (soluble sand) added for corrosion control.  We are required to do a routine Title 22 full panel of water testing for primary and secondary contaminants and inorganics every 3 years which was last completed this past year in 2023 with no anomalies from our usual safe levels of sample testing.  The DDW does onsite Sanitary Surveys approximately every 5-years and inspected the MBCSD water system in May 2021 and found the system was meeting all DDW drinking standards with no system violations or inefficiencies.  The water system had no major maintenance issues this year and the distribution system remains reliable.   We have continued to do our additional valve exercising throughout the complete distribution system along with our annual flushing routine.  The Wellntel well monitoring system installed in our primary 2002 well has continued to demonstrate that our static well levels and pump recovery times are very stable.  Over the many years, the Muir Beach water system has continued to incorporate more new technologies and redundancies into the infrastructure to safeguard, detect, and troubleshoot potential problems that can routinely occur to water systems like ours. Our Water Operator Team continues to advance their knowledge, interest, and energy managing the MB Water System and we look towards continuing a positive trend of both stability and improvement into the future.
