Wind has the potential to carry seeds long-distances and could be an important consideration in the management of natural vegetation along the U.S.-Mexico Border with border barrier infrastructure. Shrubs, native grasses, the invasive Pennisetum ciliaris (buffelgrass), soil particles and pebbles dispersed in the ecosystem, especially in maximum wind and/or precipitation events. While...

Radon is an odorless and invisible radioactive gas that is naturally released from rocks, soil, and water. According to the U.S. Environmental Protection Agency (EPA) and the U.S. Surgeon General, radon is the second leading cause of lung cancer in the United States. Recent epidemiological studies have also identified linkages between radon exposure and cerebrovascular diseases including...

This data release codifies and attributes values for potential explanatory factors to groundwater well locations and to groundwater basins in California. The groundwater sites are 282,000 wells that have water-quality data and are listed in the California State Water Resources Control Boards' Groundwater Ambient Monitoring and Assessment Program Groundwater Information System (GAMA GIS)...

This data release contains data in support of "Diverging trends in Nitrate and Phosphorus Loads and Yields Across Illinois Watersheds, 1997–2022" (Kamrath and others, 2025). It contains input and output data used to estimate total nitrate + nitrite, dissolved phosphorous and total phosphorous loads for sites in Illinois from water years 1974 to 2022. The input data includes "input-data...

We report rock and mineral K-Ar isotopic dates from 55 Cenozoic rocks and 49 pre-Cenozoic rocks from the eastern Mojave Desert in southeastern California, Nevada, and Arizona and 3 pre-Cenozoic rocks from the southern Sierra Nevada, California. For many of the samples two separate minerals were dated. We also report Ar-Ar dates from 7 pre-Cenozoic rocks in the eastern Mojave Desert.

A Lagrangian study was conducted in 2019 that followed two water masses in the Powder River from central Wyoming to southeastern Montana. The study characterized the changes of the in-stream transport of sediment and associated chemical and biological constituents. Depth-integrated water samples (using an isokinetic nozzle) and river bottom sediment samples were collected at six mainstem...

The U.S. Geological Survey (USGS), in cooperation with the U.S. Environmental Protection Agency (EPA), collected groundwater-level altitude and water-quality data from selected monitoring wells at the Petro-Chemical Systems, Inc. (Turtle Bayou) Superfund site in Liberty County, Texas on April 29 and November 13, 2024. These data were collected to obtain information that could be used to...

The Ouachita-Nevada Wood Treaters Superfund Site is a former wood-treatment facility located on approximately five acres of undeveloped land along the west side of North Main Street in Reader, Arkansas in Ouachita County. The former facility used wood treatment products containing pentachlorophenol (PCP) and heating oil, a chromium-copper-arsenate solution, and a mixture of diesel fuel...

The Falcon Refinery Superfund site (hereinafter referred to as “the site”) is in an unincorporated area of San Patricio County, approximately one mile southeast of Ingleside, Texas. The site is an inactive petroleum refinery that operated during the 1980s and consisted of 32 aboveground storage tanks (ASTs) used to store petroleum products. Since 2004, many of these ASTs have been...

This dataset is a "catalog of literature" produced in support of a review paper titled: "What Goes with the Flow: A Review of Linkages among Climate Change, Low-Flows, Water Quality, and Instream Flow Management Response across the United States". The dataset consists of six tabular sheets, each of them containing information critical to the review paper: a summary of search terms used...

The sediment core data presented here were compiled for use in a project studying the amount of sand either released from or stored within the bed sediments of San Francisco Bay, California from the 1980s to 2010s. Estimates of the change in sand storage in the bed sediments could be used in larger San Francisco Bay sand budget and transports studies as well as to inform management...
