Data

Between June 2024 and December 2024, tapwater samples were collected from 48 homes that use private well water as their drinking water source. All homes were located within a 50-kilometer radius of the 3M Cordova Facility in Cordova, Illinois, and analyzed for per- and polyfluoroalkyl substances (PFAS). The sampling effort was undertaken by the University of Iowa and samples were sent to...

Annual and seasonal trends in nitrogen and phosphorus loads, mean concentrations (flow-weighted loads), mean yields (area-weighted loads), and possible related stresses on aquatic ecology were estimated for the period December 1999 through November 2020 for each of 261,247 individual stream reaches and 81,717 12-digit hydrologic units (HUC12s) in the conterminous United States (CONUS)...

In cooperation with the Idaho Department of Water Resources (IDWR), the U.S. Geological Survey, (USGS), collected surface nuclear magnetic resonance (sNMR) and time-domain electromagnetic (TDEM) surveys at eight sites located in the Camas Prairie, Idaho between July 30 and August 2, 2024. The data were acquired to characterize the subsurface and define hydraulic properties of the shallow

This data release documents performance testing of an experimental suspended‑sediment and water‑quality collapsible‑bag sampler with point‑ or depth‑integrating capabilities, the US XPD‑24‑200. Water samples were collected at known velocities in a controlled tow‑tank environment and during lake tows using multiple sampler‑nozzle sizes. For each test, tow velocity, sample volume, and...

This data release contains sample information for a project using genotyping-in-thousands by sequencing (GT-seq) to identify to species early life coregonine fishes that were collected by the U.S. Geological Survey from Lake Superior in 2019-2021. Sample data are provided for both the larval and age-1 coregonines that underwent genetic identification and the reference fishes collected...

This data release contains sample information for Coregonus artedi, Coregonus hoyi, Coregonus kiyi, and Coregonus zenithicus collected from Lake Nipigon and the Laurentian Great Lakes that have been genotyped with restriction site-associated DNA sequencing (RAD-seq) for population genetic analysis. Sample information includes: the National Center for Biotechnology Institute BioProject...

This data release contains 6PPD-quinone (6PPDQ, 2-anilo-5-[(4-methylpentan-2- yl)amino]cyclohexa-2,5-diene-1,4-dione) concentration data from 14 water samples collected from four stream locations in New York and Pennsylvania. Samples were collected from 2025 to 2026 during storm runoff events (n = 3 - 4 per site), with detected concentrations ranging from 0.29 to 36.49 ng/L. Four samples...

In 2023, the U.S. Geological Survey conducted a reconnaissance survey of surface-water quality in areas of southern West Virginia and eastern Kentucky that have ongoing and/or historic mountaintop removal mining for coal resources. The water-quality data collected during the survey are collated in this data release.

This dataset includes high-resolution thermal infrared (TIR) and true-color images collected from crewed aircraft and a point shapefile and corresponding comma-delimited tabular data representing the longitudinal spatial patterns of water surface temperature in the surveyed streams in Tualatin River basin, Oregon. The Oregon Department of Environmental Quality (ODEQ) contracted Watershed...

Dataset includes qualitative benthic algae and plankton occurrence data from 148 discrete samples of plankton (n=58) collected with an 80-micron mesh plankton net and streambed sediment (n=90) collected using a pipettor and(or) petri dish and spatula. Samples were collected, placed on ice, and analyzed within 1-3 days. Multiple wet mount slides were prepared and examined with a Leica...

This dataset includes csv files containing the locations and attributes of landslides forming, and not-forming, dams mapped and used by Morgan et al. (2026) to model landslide dam susceptibility in the Oregon Coast Range. We also include the resulting output models of Morgan et al. (2026) predicting landslide dam susceptibility throughout the Oregon Coast Range as 100m spaced points...

Buffered geographic locations of remote-triggered cameras that recorded 1 or more black bears in Massachusetts from 2021-2023. Sixty cameras were placed on a randomly selected grid in western Massachusetts. Cameras were set and monitored by the Massachusetts Cooperative Fish and Wildlife Research Unit.
