The aquifer risk map is being developed to fulfill requirements of SB-200 and is intended to help prioritize areas where domestic wells and state small water systems may be accessing groundwater that does not meet primary drinking water standards (maximum contaminant level or MCL). 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. The Fund Expenditure Plan states the risk map will be used by Water Boards staff to help prioritize areas for available SAFER funding.<\/font><\/p>

This layer contains several reference boundaries, including boundaries\nof CV-SALTS basins with their priority status, Groundwater Sustainability\nAgency boundaries, census block group boundaries, county boundaries, and groundwater\nunit boundaries.<\/font><\/p>

Methodology for the draft aquifer risk map <\/font>available for download<\/a>.
