Estimated equivalent population using public supply surface water in the conterminous United States, CEM 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 surface water distributed across block-groups.

This dataset consists of the total estimated population using public supply surface water and groundwater combined, distributed using the urban land-use enhanced method.

Categories: Data; Types: Downloadable, GeoTIFF, Map Service, Raster; Tags: United States, drinking water, geoscientificInformation, public supply, surface water Community public supply based Hydrogeologic Mapping Units A seamless map of the major groundwater areas used by community public supply wells in the United States was needed in order to describe and compute the number of equivalent people using public supply water. This goal was met by the delineation of hydrogeologic mapping units (HMUs). An HMU is a mapped polygon, within which, all public supply wells have a common source of water. The source of water can be either a national Principal Aquifer (PA) as defined in USGS (2003) or a Secondary Hydrogeologic Region (SHR) as defined in Belitz et al. (2018). Collectively, both PAs and SHRs are referred to as Hydrogeologic Regions (HRs). The common source of water can be a single HR or multiple HRs, as HRs can overlap one another....
