The U.S. Geological Survey collected groundwater samples from 48 grid wells and 11 understanding wells screened in aquifers used for domestic supply in San Bernardino County, California, in 2018. The sites were sampled for the Mojave Basin (MOBS) Shallow Aquifer Study Unit of the California State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project’s assessment of the quality of groundwater resources used for domestic and small system drinking water supplies. The MOBS study unit covered the Upper, Middle, and Lower Mojave River groundwater basins, El Mirage groundwater basin, and part of the Harper Valley groundwater basin [California Department of Water...
The U.S. Geological Survey (USGS) has collected water-quality data at six Resource Conservation and Recovery Act (RCRA) wells at the Letterkenny Army Depot since the 1990s. Electronic data (field and analytical) for this project were put into the USGS National Water Information System (NWIS) database beginning in 2017. Analytical data include total forms of selected metals and volatile organic compounds (VOCs).

The U.S. Geological Survey collected groundwater samples from 49 wells used for domestic and small system drinking water supplies and 10 monitoring wells in San Bernardino County, California in 2018. The wells were sampled for the Mojave Basin (MOBS) Shallow Aquifer Study Unit of the California State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project’s assessment of the quality of groundwater resources used for domestic and small system drinking water supplies. Domestic and small-system wells commonly are screened at shallower depths than public-supply wells. The MOBS study unit covered the Upper, Middle, and Lower Mojave River groundwater basins, the...
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 indicated groundwater in the upper water-bearing zone might be migrating off-site toward the southwest (U.S. Environmental Protection Agency, 2016). There are concerns regarding potential risks to human health from contaminated soil vapor in existing or future structures in the area. To evaluate the status of volatile organic compound...
This U.S. Geological Survey (USGS) Data Release provides salinity and density data collected at Great Salt Lake (GSL), Utah monitoring locations during 2021–2022. Temperature, specific conductance, and dissolved oxygen were collected using an In-Situ AquaTROLL 600. Sample density was measured using an Anton Paar DMA 35Ex at 5° increments between 5° and 40° C. Practical salinity was measured at the University of Miami’s Rosenstiel School of Marine and Atmospheric Science using a Guideline Salinometer. These data were used to validate the equation of state for Great Salt Lake at salinities higher than the established range, 23–182 g/L (Naftz, et al, 2011). Data supports increasing the upper density range from 1.145...

The U.S. Geological Survey collected groundwater samples from 46 wells used for domestic and small system drinking water supplies in San Joaquin, Calaveras, and Stanislaus counties, California in 2019. The wells were sampled for the Northern San Joaquin Valley Domestic-Supply Aquifer Study Unit of the California State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project’s assessment of the quality of groundwater resources used for domestic and small system drinking water supplies. Domestic and small-system wells are commonly screened at shallower depths than public-supply wells. The Northern San Joaquin Valley study unit encompasses the Eastern San Joaquin...
This U.S. Geological Survey Data Release contains the associated data described in the Scientific Investigations Report, "Trends in water quality of selected streams and reservoirs used for water supply in the Triangle area of North Carolina, 1989-2013". Since 1989, the U.S. Geological Survey and a consortium of local governments have tracked water-quality conditions and trends in the water-supply reservoirs and streams in the Triangle area of North Carolina located within the upper Cape Fear and Neuse River Basins. Temporal trends in water-quality were analyzed for thirteen stream and eight reservoir sites. Seventeen water-quality parameters and constituents were examined at these sites.
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 contamination at the site. This data release documents the groundwater-level altitudes, field properties, and water-quality data obtained in 2023 from six of the 11 monitoring wells where similar data were collected by the U.S. Geological Survey in August and September 2020 (Braun and Becher 2022). The environmental and quality-control...
