Aquifer Risk Map

Aquifer Risk Map

This Aquifer Risk Map is 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. 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 the Water Boards staff to help prioritize areas for available SAFER funding. This is the final 2021 map based upon feedback received from a draft map published in October 2020.

They organize water quality and quantity improvement projects for water systems currently on, or at-risk of being on the HR2W list. SAFER promotes community participation, facilitates funding discussions, coordinates water system Administrator appointments, and advances sustainable alternatives such as water partnerships.
