Data Release: Blowing in the wind: anemochory in blackbrush habitat of South Texas, 2023 Data Release: Blowing in the wind: anemochory in blackbrush habitat of South Texas, 2023

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...

Geologic Radon Potential Map of the United States Geologic Radon Potential Map of the United States

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...

Potential Explanatory Variables for Groundwater Quality in California Potential Explanatory Variables for Groundwater Quality in California

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)...

Estimation of Annual and Monthly Loads of Nitrate + Nitrite, Total Phosphorous, and Dissolved Phosphorus in Illinois for Water Years 1974 to 2022 Estimation of Annual and Monthly Loads of Nitrate + Nitrite, Total Phosphorous, and Dissolved Phosphorus in Illinois for Water Years 1974 to 2022

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...

K-Ar and Ar-Ar age data for some Cenozoic and pre-Cenozoic rocks in the eastern Mojave Desert area and southern Sierra Nevada, southwestern United States K-Ar and Ar-Ar age data for some Cenozoic and pre-Cenozoic rocks in the eastern Mojave Desert area and southern Sierra Nevada, southwestern United States

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.

Physical, chemical, and biological results from a Lagrangian study of water and sediment transported by Powder River in central Wyoming and southeastern Montana, between June 27 – July 3, 2019 Physical, chemical, and biological results from a Lagrangian study of water and sediment transported by Powder River in central Wyoming and southeastern Montana, between June 27 – July 3, 2019

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...

Groundwater-level altitudes and volatile and semivolatile organic compound concentrations at the Petro-Chemical Systems, Inc. (Turtle Bayou) Superfund site, Liberty County, Texas, 2024 Groundwater-level altitudes and volatile and semivolatile organic compound concentrations at the Petro-Chemical Systems, Inc. (Turtle Bayou) Superfund site, Liberty County, Texas, 2024

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...

Groundwater-quality sampling at the Ouachita-Nevada Wood Treaters Superfund Site, Reader, Arkansas, October 2024 Groundwater-quality sampling at the Ouachita-Nevada Wood Treaters Superfund Site, Reader, Arkansas, October 2024

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...

Soil-quality sampling at the Falcon Refinery Superfund site near Ingleside, Texas, January 2025 Soil-quality sampling at the Falcon Refinery Superfund site near Ingleside, Texas, January 2025

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...

Planning for the Future of Aquatic Flows: A Comprehensive Database of River Water Quality Literature in the United States from 1997-2024 Planning for the Future of Aquatic Flows: A Comprehensive Database of River Water Quality Literature in the United States from 1997-2024

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...

Estimates of percent sand in cores collected in San Francisco Bay, California from 1990-2016 Estimates of percent sand in cores collected in San Francisco Bay, California from 1990-2016

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...
