The Aquifer Risk Map is developed to fulfill requirements of SB-200 (Monning, 2019) 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 map is made available to the public and updated annually starting January 1, 2021. This layer is part of the 2024 Aquifer Risk Map. The Fund Expenditure Plan states the risk map will be used by Water Boards staff to help prioritize areas for available SAFER funding. <\/SPAN><\/P>

This layer displays state small water system locations joined with water quality risk estimates per square mile section.<\/SPAN><\/P>

The water quality risk is based on depth-filtered, de-clustered water quality results from public and domestic supply wells.

The Aquifer Risk Map is developed to fulfill requirements of SB-200 (Monning, 2019) 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 map is made available to the public and updated annually starting January 1, 2021. This layer is part of the 2024 Aquifer Risk Map. The Fund Expenditure Plan states the risk map will be used by Water Boards staff to help prioritize areas for available SAFER funding. <\/SPAN><\/P>

This layer displays source water quality data summarized by well. This source data was aggregated to calculate the water quality risk by section for the 2024 Aquifer Risk Map.<\/SPAN><\/P>

The water quality risk is based on depth-filtered, de-clustered water quality results from public and domestic supply wells.

The Aquifer Risk Map is developed to fulfill requirements of SB-200 (Monning, 2019) 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 map is made available to the public and updated annually starting January 1, 2021. This layer is part of the 2024 Aquifer Risk Map. The Fund Expenditure Plan states the risk map will be used by Water Boards staff to help prioritize areas for available SAFER funding. <\/SPAN><\/P>

This layer displays estimated hexavalent chromium concentrations per square mile section for use in the 2024 Aquifer Risk Map. This layer contains estimated risk for hexavalent chromium only. The comparison concentration value used for hexavalent chromium was 10 ppb.<\/SPAN><\/P>

The water quality risk is based on depth-filtered, de-clustered water quality results from public and domestic supply wells.

The Aquifer Risk Map is developed to fulfill requirements of SB-200 (Monning, 2019) 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 map is made available to the public and updated annually starting January 1, 2021. This layer is part of the 2024 Aquifer Risk Map. The Fund Expenditure Plan states the risk map will be used by Water Boards staff to help prioritize areas for available SAFER funding. <\/SPAN><\/P>

This layer displays estimated nitrate concentrations per square mile section for use in the 2024 Aquifer Risk Map. This layer contains estimated risk for nitrate only.<\/SPAN><\/P>

The water quality risk is based on depth-filtered, de-clustered water quality results from public and domestic supply wells.

The Aquifer Risk Map is developed to fulfill requirements of SB-200 (Monning, 2019) 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 map is made available to the public and updated annually starting January 1, 2021. This layer is part of the 2024 Aquifer Risk Map. The Fund Expenditure Plan states the risk map will be used by Water Boards staff to help prioritize areas for available SAFER funding. <\/SPAN><\/P>

This layer displays estimated 1,2,3-trichloropropane concentrations per square mile section for use in the 2024 Aquifer Risk Map. This layer contains estimated risk for 1,2,3-Trichloropropane only.<\/SPAN><\/P>

The water quality risk is based on depth-filtered, de-clustered water quality results from public and domestic supply wells.

The Aquifer Risk Map is developed to fulfill requirements of SB-200 (Monning, 2019) 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 map is made available to the public and updated annually starting January 1, 2021. This layer is part of the 2024 Aquifer Risk Map. The Fund Expenditure Plan states the risk map will be used by Water Boards staff to help prioritize areas for available SAFER funding. <\/SPAN><\/P>

This layer displays summarized demographic information by block group. The demographic information is from the 2022 American Community Survey five-year estimates, and includes median household income (B19013_001E) and race/ethnicity data (B03002).<\/SPAN><\/P>

The water quality risk is based on depth-filtered, de-clustered water quality results from public and domestic supply wells.
