Data

This dataset includes the magnetotelluric (MT) sounding data collected in 1989 across the Idaho Batholith, Payette National Forest, Idaho, by the U.S. Geological Survey (USGS). The primary focus is on geologic elements that relate to the Late Cretaceous Idaho batholith geometry and the development of the Yellow Pine mining district and Stibnite mining area. Twenty MT soundings along one...

This data release contains time-lapse self-potential, electric resistivity tomography, hydrographic, and weather data acquired during a geoelectric monitoring survey of the lower Rio Grande riverbed in the Mesilla Basin of southeast, New Mexico. The monitoring survey was performed by the U.S. Geological Survey (USGS) in copperation with New Mexico State University (NMSU), Elephant Butte...

The Geneva Industries/Fuhrmann Energy Superfund Site in southeastern Houston, Texas was historically used as a site for petroleum exploration and petrochemical production and is currently (2023) inactive. Previous remedies to clean up the contaminated site included: excavation and off-site disposal of polychlorinated biphenyl-contaminated soils, capping of residual water on-site with a...

In cooperation with state and county agencies, including the Chester County Water Resources Authority (CCWRA), the U.S. Geological Survey (USGS) has collected discrete stream samples for analysis of chloride concentrations at three real-time streamflow and water-quality monitoring (specific conductance) stations located in Chester County, Pennsylvania. Data were collected from 2010-2023...

This dataset documents depth to groundwater measurements made from wells screened in the Chicot aquifer, Evangeline aquifer, Jasper aquifer, Burkeville confining unit, Catahoula confining unit, or a combination of these hydrogeologic units in the greater Houston area, Texas for 2022. The U.S. Geological Survey (USGS) prepared this dataset in cooperation with the Harris‐Galveston...

The U.S. Geological Survey (USGS) in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, Lone Star Groundwater Conservation District, and Brazoria County Groundwater Conservation District produced this dataset of groundwater‐level altitudes and groundwater‐level altitude changes in the Chicot and Evangeline aquifers (undifferentiated...

In 2023, the U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, collected groundwater-level altitude and water-quality data from monitoring wells at the Petro-Chemical Systems, Inc. (Turtle Bayou) Superfund Site in Liberty County, Texas. The data were collected to obtain information that could be used to provide an update on the status of groundwater

The Triangle Chemical Company Superfund site, in Orange County, Texas, was a chemical mixing and blending facility in the 1970s. According to the Environmental Protection Agency (EPA), poor waste management practices resulted in soil and groundwater contamination and fish-kills in Coon Bayou (U.S. Environmental Protection Agency, 2023). The Five-Year Review of the Triangle Superfund Site...

The U.S. Geological Survey (USGS), in cooperation with the Oklahoma Water Resources Board (OWRB), constructed a finite-difference numerical groundwater-flow model of the Washita River aquifer by using MODFLOW-2005 (Harbaugh, 2005) with the Newton formulation solver (MODFLOW-NWT). The 1973 Oklahoma Groundwater Law requires that the OWRB conduct hydrologic investigations of the State’s...

The Edwards aquifer in south-central Texas is one of the most permeable and productive aquifers in the United States and is the major source of public water supply for Bexar, Comal, Hays, Medina, and Uvalde Counties. The Edwards aquifer also supplies large quantities of water for use in agriculture, business, and industry in the region. The major artesian springs of the Edwards aquifer...

The semi-arid Walla Walla River Basin (WWRB) spans 1,777 square miles in Washington and Oregon and supports a diverse agricultural region as well as cities and rural communities that are partially reliant on groundwater. Historically, surface-water and groundwater data have been collected in the WWRB by federal, state, local, and tribal governments, irrigation districts, universities...
