Reliable scientific data
We collect, analyze, and distribute data to the public and stakeholders that describe various water-related issues and resources and that support interpretive studies and decision-making.

Historic Water Chemistry Data for Thermal Features, Streams, and Rivers in the Yellowstone National Park Area, 1883-2021
Yellowstone National Park (YNP; Wyoming, Montana, and Idaho, USA) contains more than 10,000 hydrothermal features, several lakes, and four major watersheds. For more than 140 years, researchers at the U.S. Geological Survey and other scientific institutions have investigated the chemical compositions of hot springs, geysers, fumaroles, mud pots, streams, rivers, and lakes in YNP and surrounding ar
PHREEQC files for geochemical simulations in the Ohio River alluvial aquifer of West Virginia
This data release includes PHREEQC files used for geochemical models in the Ohio River alluvial aquifer of West Virginia. The associated publication by McAdoo and Connock (2024) should be consulted to understand the purpose and limitations of these simulations and data. The wateq4f database (Ball and Nordstrom, 1991) was used for the PHREEQC simulation. A report by Parkhurst and Appelo (2013) ser
Data for Statewide Reconnaissance of Per- and Polyfluoroalkyl Substances in Rivers and Streams of Virginia, 2022-2023
These data were collected in cooperation with the Virginia Department of Environmental Quality (VADEQ) to document the occurrence of Per- and Polyfluoroalkyl Substances (PFAS) in streams and rivers of Virginia. Specifically, this effort was initiated to:
1. Collect and analyze samples for PFAS at USGS-sampling stations in the Chesapeake Bay River Input Monitoring Network and Non-Tidal Network;
2
Interpolated groundwater levels and altitudes for Monroe County, West Virginia, 2017-2019
This interpolated ground-water level altitude product, for Monroe County, WV, was derived from ground-water-level data obtained from a U.S. Geological Survey (USGS) synoptic survey of 257 ground-water wells during October 23, 2017 through September 19, 2019, and selected points from the National Hydrography Dataset (NHD) to represent equal-altitude contour lines of ground-water levels in 50-foot i
Fluorescein and Rhodamine WT concentration and recovery data for select samples collected in Monroe County, West Virginia, in August and September 2019
Fluorescein and Rhodamine WT dye-tracer injections were performed in Monroe County, West Virginia to determine groundwater flow paths and identify the location of the groundwater divide within the Greenbrier karst aquifer in the area south of Union, West Virginia. Fluorescein was injected in a swallet on Burnside Branch upstream of Steel's cave (37° 33' 56.0" latitude -80° 32' 57.6" longitude) and
Upper Colorado River Basin Accumulated Wastewater Ratios
A wastewater reuse model was applied to the Upper Colorado River basin to assess the percent of accumulated wastewater (ACCWW%) from municipal and industrial wastewater treatment plants (WWTPs) in each initialized (that is, has an assigned hydrosequence number for flow-routing) National Hydrography Dataset Version 2.1 (NHDPlus V2.1) stream segment. Model inputs included (1) NHDPlus V2.1 stream geo
Potomac River ADCP Bathymetric Survey, October 4-7, 2021
Bathymetric LiDAR technology was used to collect riverbed elevation data along the Potomac River. In support of this effort, a bathymetric survey with a boat-mounted acoustic Doppler current profiler (ADCP) was conducted in the study area during October 4-7, 2021. The study area consisted of four verification reaches on the Potomac River including: 1) Williamsport accessed through the Williamsport
Literature Summary of Indicators of Water Vulnerability in the Western US 2000-2022
This data release contains records from research focused on understanding social vulnerability to water insecurity, resiliency demonstrated by institutions, and conflict or crisis around water resource management. This data release focuses on social vulnerability to water insecurity.
The data were derived from a meta-analysis of studies in the empirical literature which measured factors of social
Water withdrawal data of selected public water systems in West Virginia, 2014 - 2020
These data were collected to support a drought-vulnerability assessment and near real-time drought awareness web tool for public water systems (PWS) on surface water supply in West Virginia. PWS withdrawal rates were evaluated against USGS low-flow stream statistics, modeled streamflow from the National Water Model, and thresholds from state drought response guidelines and ecological-flow literatu
Selected inputs for examining the complex relations between climate and streamflow in the Mid-Atlantic region of the United States
Streams provide water for human activities and consumption in much of the world. Streamflow is largely controlled by climate forces, therefore it is likely sensitive to climate changes. We analyzed daily air temperature (AT), precipitation (P), and stream discharge (Q) metrics for 124 watersheds in Maryland, Virginia, and North Carolina, United States, from 1981 through 2020. Spatial-raster datase
Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay River Input Monitoring stations: Water years 1985-2022
Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in major rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay River Input Monitoring (RIM) Network stations for the period 1985 through 2022. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach called WR
Per- and polyfluoroalkyl Substances in Drinking Water at Select Public Water Systems in West Virginia, 2022
These data were collected to understand the occurrence of per- and polyfluoroalkyl substances in drinking water samples at public water systems identified to have perfluorooctanoic acid or perfluorooctane sulfonic acid above laboratory reporting levels in previously collected raw-water samples, and provide a review of the analytical results.
