Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The Aquifer Risk Map is developed to fulfill requirements of SB-200 (Monning, 2019) 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. In accordance with SB-200, the map is made available to the public and updated annually starting January 1, 2021. This layer is part of the 2024 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></P><P><SPAN>This layer displays summarized demographic information by block group. The demographic information is from the 2022 American Community Survey five-year estimates, and includes median household income (B19013_001E) and race/ethnicity data (B03002).</SPAN></P><P><SPAN>The water quality risk is based on depth-filtered, de-clustered water quality results from public and domestic supply wells.
