Maps and Data

SAFER maintains a variety of data tools to support a better understanding of California’s drinking water reality. The below dashboards provide insight into water systems that are failing or at-risk of failing to provide safe drinking water, where groundwater systems may be at risk, and more.

SAFER Dashboard

This map illustrates the current Failing: Human Right to Water systems and the results of the Risk Assessment for California community water systems with up to 30,000 service connections or 100,000 population served and K-12 schools. The Risk Assessment is a component of the Drinking Water Needs Assessment. Users can search or filter this information by public water system ID, system name, county, regulating agency, system size, etc. The data used to identify At-Risk systems is available in the 2022 Risk Assessment Results Spreadsheet.

The list of failing systems is updated daily.

Drinking Water System Outreach Tool

A map-based tool for California water system professionals and members of the public. Public water systems and state small water system locations are aggregated as one layer for use with various analysis tools. Several other contextual layers are available for analysis, including, tribal land areas; previously completed drinking water partnerships and consolidations; watersheds; basins; disadvantaged community status; CalEnviroScreen health hazard scores; well aquifer risk, California counties, and crop mapping. Additional layers may be available upon request.

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 safe drinking water standards. In accordance with SB-200, this map is made available to the public and is updated yearly. This map is used to inform the SAFER Needs Assessment and the Fund Expenditure Plan to prioritize areas for available SAFER funding.

Water System Partnership

This Water System Partnership Map can be used to explore completed consolidations and other water partnerships as tracked by the SAFER Engagement Units. The SAFER Engagement Units are a team of engineers and program specialists within the Division of Drinking Water. Their mission is to support water systems in achieving long-term sustainability. They organize water quality and quantity improvement projects for water systems currently on, or at risk of Failing HR2W criteria. SAFER promotes community participation, facilitates funding discussions, coordinates water system Administrator appointments, and advances sustainable alternatives such as water partnerships.
