Combined Risk - 2022 Needs Assessment Final

This web application displays combined risk (water shortage + water quality) for domestic wells and state small water systems. This map is for use in the 2022 SAFER Needs Assessment. There several layers available. By default, there is a filter turned on that only displays data for areas with at least one domestic well or state small water system. This filter can be turned off in the "filter" widget. Combined Risk: The combined risk is calculated by adding water shortage risk score to water quality risk score and dividing by 2. Water Quality Risk: This data is from the 2022 Aquifer Risk Map. Water Shortage Vulnerability: This data is from the Department of Water Resources Water Shortage Vulnerability Tool for self-supplied communities. CalEnviroScreen 4.0 Results (OEHHA): for each census tract, the CalEnviroScreen 4.0 score is displayed, including overall score, pollution burden score, population burden score, and race/ethnicity population percentages. This data is from CalEnviroScreen 4.0. All PLSS sections also display the estimated count of domestic well locations (derived from Department of Water Resources Online System for Well Completion Reports) and the count of known state small water systems (from the Division of Drinking Water).
