Service Description: <span style='line-height: 107%; font-family: Calibri, sans-serif;'><font size='3'>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></span><div><font face='Calibri, sans-serif' size='3'><br /></font><div>Methodology for the draft aquifer risk map <a href='https://gispublic.waterboards.ca.gov/portal/home/item.html?id=5f94cf5ca2a04f66a3dcfab29cf6c764' target='_blank'>available for download</a>.</div><div><br /><div><p>This layer shows the locations of state small and public water systems, as well as domestic well density. The state small water system locations were collected by the Rural Community Assistance Corporation. The locations are approximate and may not exactly represent well locations or service boundaries. The domestic well density per square mile is based on well completion report data from the Department of Water Resources <a href='https://dwr.maps.arcgis.com/apps/webappviewer/index.html?id=181078580a214c0986e2da28f8623b37'>Online System for Well Completion Reports</a>.
