Reddy 2018 Publication Scientific Investigation Report SIR 2018-5091 Reston, Virginia U.S. Geological Survey https://doi.org/10.3133/sir20185091 The Groundwater Usage for Public Supply dataset contains attributes pertaining to groundwater use in the glaciated conterminous United States summarized by county. The attributes were computed from total groundwater usage by county compiled by Maupin and others (2010), and from inventories of water-use records for 71,267 public water-supply systems by Buchwald and others (in press). Source aquifers (Quaternary sediments or bedrock) were assigned for the public water-supply systems based on reported data (e.g., well construction records, aquifer delineation maps), or based on well depth and the Quaternary sediment thickness. Water usage rates are reported on an average annual, areal basis in units of millimeters per year, to facilitate comparison with estimated recharge rates from Westenbroek and others (in press). The Groundwater Usage for Public Supply dataset presents maps of groundwater usage in the glaciated conterminous United States, including: a) average annual groundwater withdrawals in 2010, b) average annual public-supply withdrawals in 2010, c) percentage of public-supply withdrawals from Quaternary sediments, and d) annual groundwater withdrawals in 2010 as a percent of recharge. 2010 publication date Complete None planned -124.969069883 -65.343237884 50.932504994 35.090811167 USGS Thesaurus hydrogeology None water use Quaternary sediments recharge groundwater NAWQA USGS Metadata Identifier USGS:5a68d920e4b06e28e9c7225b none Connecticut Illinois Indiana Iowa Kansas Maine Massachusetts Michigan Minnesota Missouri Montana Nebraska New Hampshire New Jersey New York North Dakota Ohio Pennsylvannia South Dakota Vermont Washington Wisconsin None Users are advised to read the data set's metadata thoroughly to understand appropriate use and data limitations.

No formal accuracy tests were conducted. These data are believed to be logically consistent, although no formal tests were conducted. The dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. Uncertain. The original source datasets were compiled from a map scale of 1:100,000. A formal accuracy assessment of the horizontal positional information in the dataset has not been conducted. A formal accuracy assessment of the vertical positional information in the data set has either not been conducted, or is not applicable.
