Assembly Districts

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. This layer contains several reference boundaries, including: California County boundaries Census Tract boundaries with Disadvantaged Community Status (based on Median Household Income) California Assembly District boundaries California Senate District boundaries California Regional Water Board boundaries CV-SALTS priority groundwater basins Groundwater Sustainability Agency boundaries Groundwater Unit boundaries
