Guidance For Residents Using Individual Private Intakes



LAKE COUNTY, CA (July 23, 2022) – Our community’s defining feature, Clear Lake, is an expansive and biologically diverse ecosystem. As such, it is dynamic in water quality. This year, due to persistent drought and heat, we are witnessing unprecedented levels of cyanotoxins in some areas of Clear Lake. For Lake County residents with individual water systems that draw water directly from the lake using a private intake, drinking water may become unsafe when high levels of toxins are present. Of particular concern are those with individual water systems who live around the Sulphur Bank Mine, and along the shore of Clear Lake’s Lower and Oaks Arms. Similar to last year, potentially harmful concentrations of cyanotoxins have been identified in these areas of the lake. Local public health and water quality experts are concerned there may be impacts to the health of those using individual water systems, if they are not effectively filtering out these toxins. There is no easy fix if you are getting your water in this way - boiling or putting chemicals in the lake or tap water does not eliminate the toxins. Public water systems are able to effectively remove toxins, and will continue to provide tap water which has gone through a multifaceted treatment process. Even public water systems which draw water from Clear Lake as their raw water source continue to provide water that is safe for consumption, and continually monitored to maintain compliance with State water quality requirements. Please contact your Public Water System, if you would like more information. Last year, in collaboration with local officials and the State Water Resources Control Board, Golden State Water Company and Mt. Konocti Mutual Water Company established filling stations to provide safe, drinkable water to affected community members. This water continues to be available to meet very basic household needs such as drinking, cooking, brushing teeth, preparing food, mixing baby formula, making ice, and giving water to pets. Those who choose to utilize these generously provided resources are asked to please limit consumption to 25 gallons per week per household. Affected residents should bring their own clean containers that are meant for beverage storage to whichever location is most convenient.
