Johnson, T.D., Belitz, K., Kauffman, L.J., Wilson, J.T., and Watson, E., 2021. Estimated equivalent population using groundwater for public supply domestic use in the conterminous U.S. 2010, hydrogeologic mapping units, and wells used (ver. 2.0, March 2023): U.S. Geological Survey data release, https://doi.org/10.5066/P97Y8D6Q.

Summary

The population using public supply drinking water was mapped in two ways: the census enhanced method (CEM) evenly distributes the population across the census block-group, and the urban land-use enhanced method (ULUEM) distributes the population only to certain urban land use designations in order to more precisely locate public supply users. This dataset consists of the estimated population using public supply groundwater distributed across census block-groups.
