This U.S. Geological Survey (USGS) Data Release provides derivative statistics of water used by Kansas public-supply systems in 2014. Gallons per capita per day is calculated using self-reported information in the “Part B: Monthly Water Use Summary” and “Part C: Population, Service Connections, and Water Rates” sections of the Kansas Department of Agriculture, Division of Water Resources' (DWR) annual municipal water use report (see appendixes at http://dx.doi.org/10.3133/ds964 for an example of a municipal water use report form.) Percent unaccounted for water is calculated using self-reported information in “Part B: Monthly Water Use Summary” of the DWR’s municipal water-use report. The published statistics from the previous 4 years (2010–2013) are also shown with the 2014 statistics and are used to calculate a 5-year average. Derivative statistics of 2010, 2011, 2012, 2013, 2014, and 5-year averages for gallons per capita per day (gpcd) are also provided by the Kansas Water Authority's 14 regional planning areas, and the DWR regions used for analysis of per capita water use in Kansas. An overall Kansas average (yearly and 5-year average) is also calculated. Kansas state average per captia use in 2014 was 108 gpcd.

This U.S. Geological Survey (USGS) Data Release provides derivative county-level statistics of water used by Kansas irrigators in 2014.

This dataset provides the calculated proportion of people using publicly supplied groundwater (PSGF) for each county in the conterminous U.S. The county boundaries and the PSGF represent the year 2015.

This dataset describes irrigation water use in Kansas in 2016. Volumes of water used, irrigated area, and irrigation application depths are provided for three sets of subareas: (1) Irrigation water use analysis regions that include Groundwater Management Districts (GMDs) with the areas outside of GMDs divided into eastern, central, and western Kansas; (2) Regional Planning Areas (RPAs), which are 14 areas determined by the Kansas Water Office based on hydrologic and administrative boundaries, each with a set of goals outlined in the Kansas Water Vision (https://kwo.ks.gov/water-vision-water-plan/water-vision); and (3) the 105 Kansas counties. Volumes of water used, irrigated area, and application depths are also presented for the subareas by crop type and by irrigation system type. Volumes of water used, irrigated area, and application depth are also provided for ditch companies and irrigation district conveyances.

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 US 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. This dataset includes public-supply water systems that furnish their own groundwater supply, purchase groundwater from a neighboring water system, or are mixed water systems that use both ground- and surface water. Groundwater sources include wells, springs, and cross-connections to another public groundwater system. Systems that use exclusively surface water are excluded from this dataset. The surface-water sources and withdrawals of mixed water systems are excluded; however, some population served values might include persons served surface water. Groundwater-use data that were collected from various agencies and resources spanned 2005-14, with a target year of 2010. Of the compiled withdrawal records, 95 percent were within the last five years, 2009-14, and 79 percent were from 2010. The year 2010 was chosen because it is the most recent year the USGS 5-year compilation report was published in United States Geological Survey (USGS) Circular 1405 (Maupin and others, 2014). The goal was to differentiate groundwater withdrawals from unconsolidated sediments of the Quaternary Period, glacial sand and gravel deposits and stream-valley alluvium, from other non-Quaternary aquifers, mostly bedrock aquifers. There are five aquifer types defined in this study, which are Quaternary, Cretaceous (unconsolidated deposits of the Cretaceous Period), Bedrock, Mixed, and Unknown. The water-use records include data from the United States Environmental Protection Agency (USEPA) and state agency databases. These records include 1) identifiers for the water system in the USEPA's Safe Drinking Water Information System (SDWIS) database, 2) type of public water supply system, 3) location, 4) population served by the system, 5) withdrawal rates, 6) well construction information, and 7) aquifer used. Most water systems and water sources were identified and located from the Safe Drinking Water Information System (SDWIS) (USEPA, 2013). Information on withdrawal rates, aquifer source, and well construction were compiled and cross-referenced from state and federal databases. Every water system and groundwater source had a withdrawal rate calculated or estimated. 90 percent (64,151 of 71,566 records) of the water system records had aquifer type assigned (either matched by associated records or estimated), and 41 percent (42,861 of 103,688 records) of the groundwater source records had well depth matched or inferred. The glacial aquifer system is an important source of water supply for the United States. Around 2010, total population served by groundwater from public water systems within the glaciated region is 42.9 million persons, and around 2010, total public-supply withdrawal is around 5,367 cubic hectometers per year (hm3/yr) or 3,884 million gallons per day (Mgal/d). Exactly half of the total public-supply withdrawal was from Quaternary sediments, more if some part of the withdrawals from mixed and unknown aquifer types is included.

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 U.S. Geological Survey is developing national water-use models to support water resources management in the United States. Model benefits include a nationally consistent estimation approach, greater temporal and spatial resolution of estimates, efficient and automated updates of results, and capabilities to forecast water use into the future and assess model uncertainty. The term “reanalysis” refers to the process of reevaluating and recalculating water-use data using updated or refined methods, data sources, models, or assumptions. In this data release, water use refers to water that is withdrawn by public and private water suppliers and includes water provided for domestic, commercial, industrial, thermoelectric power, and public water uses, as well as water that is consumed or lost within the public supply system. Consumptive use refers to water withdrawn by the public supply system that is evaporated, transpired, incorporated into products or crops, or consumed by humans or livestock. This data release contains data used in a machine learning model (child item 2) to estimate monthly water use for communities that are supplied by public-supply water systems in the conterminous United States for 2000-2020. This data release also contains associated scripts used to produce input features (child items 4 - 8) as well as model water use estimates by 12-digit hydrologic unit code (HUC12) and public supply water service area (WSA). HUC12 boundaries are in child item 3. Public supply delivery and consumptive use estimates are in child items 1 and 9, respectively. First posted: November 1, 2023 Revised: August 8, 2024 This version replaces the previous version of the data release: Luukkonen, C.L., Alzraiee, A.H., Larsen, J.D., Martin, D.J., Herbert, D.M., Buchwald, C.A., Houston, N.A., Valseth, K.J., Paulinski, S., Miller, L.D., Niswonger, R.G., Stewart, J.S., and Dieter, C.A., 2023, Public supply water use reanalysis for the 2000-2020 period by HUC12, month, and year for the conterminous United States: U.S. Geological Survey data release, https://doi.org/10.5066/P9FUL880 Version 2.0 This data release has been updated as of 8/8/2024. The previous version has been replaced because some fractions used for downscaling WSA estimates to HUC12 did not sum to one for some WSAs in Virginia. Updated model water use estimates by HUC12 are included in this version. A change was made in two scripts to check for this condition. Output files have also been updated to preserve the leading zero in in the HUC12 codes. Additional files are also included to provide information about mapping the WSAs and groundwater and surface water fractions to HUC12 and to provide public supply water-use estimates by WSA. The 'Machine learning model that estimates total monthly and annual per capita public supply water use' child item has been updated with these corrections and additional files. A new child item 'R code used to estimate public supply consumptive water use' has been added to provide estimates of public supply consumptive use. This page includes the following files: PS_HUC12_Tot_2000_2020.csv - a csv file with estimated monthly public supply total water use from 2000-2020 by HUC12, in million gallons per day PS_HUC12_GW_2000_2020.csv - a csv file with estimated monthly public supply groundwater use for 2000-2020 by HUC12, in million gallons per day PS_HUC12_SW_2000_2020.csv - a csv file with estimated monthly public supply surface water use for 2000-2020 by HUC12, in million gallons per day PS_WSA_Tot_2000_2020.csv - a csv file with estimated monthly public supply total water use from 2000-2020 by WSA, in million gallons per day PS_WSA_GW_2000_2020.csv - a csv file with estimated monthly public supply groundwater use for 2000-2020 by WSA, in million gallons per day PS_WSA_SW_2000_2020.csv - a csv file with estimated monthly public supply surface water use for 2000-2020 by WSA, in million gallons per day Note: 1) Groundwater and surface water

This dataset presents the total estimated monthly public-supply water withdrawal by 12-digit hydrologic unit code (HUC12) in the conterminous United States for 2015. Public-supply water use was estimated by spatially and temporally downscaling available data from each state. The total represents combined groundwater and surface water withdrawals for 83,178 watersheds. Public supply refers to water withdrawn by public and private water suppliers that provide water for cities, towns, rural water districts, mobile-home parks, Native American Indian reservations, and military bases. Public-supply facilities are classified under the Standard Industrial Classification (SIC) 4941 and provide water to at least 25 people or have a minimum of 15 connections. Water withdrawals are used mostly for domestic purposes, but also serve other customers such as commercial and industrial establishments. These monthly estimates by HUC12 support USGS National Integrated Water Availability Assessments Water Use Maps.
