Published by U.S. EPA Office of Research and Development (ORD) | U.S. Environmental Protection Agency | Metadata Last Checked: August 02, 2025 | Last Modified: 2024-11-01
This dataset contains the results of EPAs estimates for domestic water supply in The United States for 2020 census blocks. The file is a comma-delimited text file, which contains records for 2020 census blocks. This data can be used to estimate the number of housing units and populations that are estimated to be using either private water supplies such as domestic wells or connected to a community water system. These results are estimates and should not be used to convey exact counts of well or public water users. For a full description of the data, please refer to the GitHub page: https://github.com/USEPA/ORD_Water_Source_2020/tree/main/outputs.
