Per- and Polyfluoroalkyl Substances in Drinking Water at Select Public Water Systems in West Virginia, 2024 (ver. 2.0, September 2025) Per- and Polyfluoroalkyl Substances in Drinking Water at Select Public Water Systems in West Virginia, 2024 (ver. 2.0, September 2025)
These data were collected to understand the occurrence of per- and polyfluoroalkyl substances (PFAS) in drinking water samples at selected public water systems in West Virginia identified to have detections for PFAS above laboratory reporting levels in previously collected raw-water samples (McAdoo and others, 2022). These data are stored in the USGS National Water Information System...
Landslide, soil, and vegetation measurements following an atmospheric river storm on January 9, 2023, in the Santa Ynez Mountains, California, USA Landslide, soil, and vegetation measurements following an atmospheric river storm on January 9, 2023, in the Santa Ynez Mountains, California, USA
An atmospheric river storm on January 9, 2023, produced widespread landsliding in the Santa Ynez Mountains in Santa Barbara County and Ventura County, California (USA). Landslides occurred in the footprint of the 2008 Tea Fire, 2009 Jesusita Fire, 2017 Thomas Fire, and 2019 Cave Fire, as well as in areas that had not burned in more than 15 years. Most of these landslides were shallow...
Lake Ontario May-July Larval Fish Survey 2024 Lake Ontario May-July Larval Fish Survey 2024
This dataset includes larval fish catches, species identifications, total length measurements, and relevant covariate data from a larval fish community survey of the U.S. waters of Lake Ontario. Sites were surveyed along a bottom depth gradient of 5 to 225 meters, covering a range of nearshore and offshore habitat between the months of May and July 2024. Vessel and gear descriptions are...
Invertebrate community datasets from before and after piscicide application in two high elevation Rocky Mountain streams in Colorado, 2015 through 2020 Invertebrate community datasets from before and after piscicide application in two high elevation Rocky Mountain streams in Colorado, 2015 through 2020
In western United States streams, Oncorhynchus virginalis stomias (Greenback Cutthroat Trout; GBCT) was thought to be extinct; however, a genetically verified population was identified and used for subsequent conservation efforts to reestablish populations. To restore native trout habitat, stream reaches upstream of a dispersal barrier are treated with a piscicide (rotenone) to remove...
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...
