Uptake of Per- and Polyfluoroalkyl Substances by Fish, Mussel, and Passive Samplers in Mobile Laboratory Exposures using Groundwater from a Contamination Plume at a Historical Fire Training Area, Cape Cod, Massachusetts - Chemical and Biological Data from Uptake of Per- and Polyfluoroalkyl Substances by Fish, Mussel, and Passive Samplers in Mobile Laboratory Exposures using Groundwater from a Contamination Plume at a Historical Fire Training Area, Cape Cod, Massachusetts - Chemical and Biological Data from
This data release presents chemical and biological results from an investigation of the uptake of per- and polyfluoroalkyl substances (PFAS) from groundwater contaminated by fire training activities on Cape Cod, Massachusetts. Exposure experiments were conducted from August 29 to September 21, 2018 using groundwater from a relatively uncontaminated reference site and a fire training area
Model data archive—Trends in Selected Environmental, Anthropogenic, and Water-Quality Characteristics in the Upper White River Basin, Indiana, 1991–2020 Model data archive—Trends in Selected Environmental, Anthropogenic, and Water-Quality Characteristics in the Upper White River Basin, Indiana, 1991–2020
This archive contains input files used in regression analyses to estimate concentrations and flux of total phosphorus, nitrate plus nitrite, total Kjeldahl nitrogen, and total suspended solids at selected locations on the Upper White River and output files containing annual estimates of flux and mean daily concentrations.of those same constituents, along with their 90 percent prediction...
MODFLOW-NWT model used to evaluate the groundwater availability of the Columbia Plateau Regional Aquifer System, Washington, Oregon, and Idaho MODFLOW-NWT model used to evaluate the groundwater availability of the Columbia Plateau Regional Aquifer System, Washington, Oregon, and Idaho
A three-dimensional groundwater flow model (MODFLOW-NWT) of the Columbia Plateau Regional aquifer (CPRAS) in Washington, Oregon, and Idaho was developed to provide an integrated understanding of the hydrologic system to implement effective water-resource management strategies. The U.S. Geological Survey (USGS) Groundwater Resources Program assessed the groundwater availability as part of...
Digital database of previously published subsurface unit tops from a 3D Model of the Anadarko Basin Province Digital database of previously published subsurface unit tops from a 3D Model of the Anadarko Basin Province
This digital data release contains gridded elevation surfaces for twenty-six (26) subsurface horizons, a grid of the estimated thickness of strata eroded during the Cenozoic, and fault traces at the level of the Precambrian surface from a previously published 3D geologic model of the Anadarko Basin Province (Higley and others, 2014). In the original release of the 3D model, elevation...
Drainage basins for selected transboundary streams in south-east Alaska and Canada through 2022 Drainage basins for selected transboundary streams in south-east Alaska and Canada through 2022
This dataset consists of drainage basin boundaries for selected transboundary basins draining to the Gulf of Alaska in south-east Alaska. Basins were delineated to the basin outlet using a tidal datum of mean high water (MHW). The drainage basins are provided as polygons attributed with basin drainage area and as polylines attributed with the data source for each line segment...
