Summary

This dataset describes public-supply groundwater use by aquifer type within the glaciated conterminous United States between 2005 and 2014. All or part of 24 states within this glaciated region were included. The U.S. Safe Drinking Water Act defines a "public water system" as an entity that provides water for human consumption through pipes or other constructed conveyances to at least 15 service connections or serves an average of at least 25 people for at least 60 days out of the year (United States Environmental Protection Agency, 1998). Water may be used for several purposes such as for commercial, industrial, and residential use, or may be used only for one specific purpose such as for residential use.

Purpose

The USGS National Water Quality Assessment (NAWQA) project is assessing the quality of groundwater resources in Glacial Principal Aquifer System. Specific objectives include determining the distributions and trends of contaminants of concern at the depths used for domestic and public drinking-water supply, and applying an understanding of how land use, climate and natural factors affect water quality to determine the susceptibility of groundwater resources to degradation. Groundwater-flow models of selected areas were constructed to estimate groundwater ages to improve our understanding of the groundwater vulnerability to contamination. Site-specific water use, well construction, and location information are needed to support these modeling efforts and to assess where and to what degree the glacial deposits are being used for public water supply. Public-supply data can be used by 1) USEPA to update their SDWIS inventory; by 2) USGS scientists as part of their 5-year water-use compilations, to add to the public-supply groundwater well inventory in the USGS Site-specific Water-Use Data System (SWUDS), or to link SDWIS records with state water-use records; and 3) others to support hydrologic modeling and investigations, trend analyses to quantify past, current, and future use, and management of local and regional water resources.
