View In: ArcGIS JavaScript ArcGIS Online Map Viewer ArcGIS Earth ArcGIS Pro

Service Description: 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.

Methodology for the draft aquifer risk map available for download.

This layer shows domestic well density. The domestic well density per square mile is based on well completion report data from the Department of Water Resources Online System for Well Completion Reports, excluding wells drilled prior to 1970.
