We are currently monitoring advisories from the State Water Resources Control Board regarding COVID-19. The provision of potable water to our customers is an essential function and we will continue to operate in a normal capacity. According to the World Health Organization, the “presence of the COVID-19 virus has not been detected in drinking water supplies and based on current evidence the risk to water supplies is low.” Public water systems that utilize groundwater sources maintain protective physical measures, including soil barriers, to ensure that water sources are protected from pathogens, including viruses. The most up to date information regarding coronavirus and your drinking water can be found at our website.

CALIFORNIA WATER BOARDS FACT SHEET
Reminder About California’s Drinking Water Systems
State-Required Treatment Process Removes Viruses, Including COVID-19
· California’s comprehensive and safe drinking water standards require a multi-step treatment process that includes filtration and disinfection. This process removes and kills viruses, including coronaviruses such as COVID-19, as well as bacteria and other pathogens.
· The State Water Board’s Division of Drinking Water establishes and enforces drinking water standards that ensure the delivery of pure, safe, and potable water. In addition to health-based water quality standards, treatment facilities must comply with stringent performance measures to ensure treatment processes are continuously operating at peak performance.
· The treatment process must destroy at least 99.99% of viruses. The limited number that might pass through the removal process are quickly inactivated in the disinfection process, typically in less than 10 minutes. All treatment facilities for surface water sources in California are required to maintain disinfection facilities sufficient to destroy giardia cysts, which are much more resilient than viruses.
· COVID-19 is transmitted person to person, not through water, according to the Centers for Disease Control and Prevention.
· Public water systems that utilize groundwater sources maintain protective physical measures, including soil barriers, to ensure that water sources are protected from pathogens, including viruses. In addition, most of these systems use chlorine disinfection to inactivate viruses or bacteria that might find their way into the water.
· All public water systems in California are routinely monitored for bacteria to ensure that water delivered to customers is free of disease-causing agents. Other parameters, including temperature, pH, turbidity, chlorine residual, electrical conductivity, lead and copper, corrosion indices and disinfection byproducts, are monitored to alert operators about changing water quality conditions and avert potential problems.
· The State Water Board works closely with local water systems to ensure the safety of water that flows through public water systems to residential customers.
