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 2020 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 due and completed in 2020 with no anomalies from our usual safe levels of sample testing.  The water system had no major maintenance issues this year and the distribution system remains reliable.
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 brings much advanced knowledge, interest, and energy to managing the MB Water System and we look towards continuing a positive trend of improvement into the future.
