In accordance with SB-200, the risk map is to be made available to the public and is to be updated annually starting January 1, 2021. This layer is part of the 2022 Aquifer Risk Map. The Fund Expenditure Plan states the risk map will be used by Water Boards staff to help prioritize areas for available SAFER funding.</span><div style='font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;'><font style='font-family:inherit;'><br /></font><div style='font-family:inherit;'><font style='font-family:inherit;'>This layer contains summarized water quality risk per square mile section and per well point. The water quality risk is based on depth-filtered, de-clustered water quality results from public and domestic supply wells for all contaminants with an MCL (plus hexavalent chromium)</font>.
