Data

These datasets support the conclusions in the journal article entitled "Population vulnerability of residents, employees, and cruise-ship passengers to tsunami hazards in complex seismic regions: a case study of the U.S. Virgin Islands" as described in the abstract below: Reducing the potential for loss of life from tsunamis is challenging on islands located in complex seismic regions...

This dataset contains chemistry results for water, sediment, and various tissue samples collected upstream and downstream of a PFAS source (treated industrial wastewater). Samples were analyzed by a USGS laboratory (National Water Quality Laboratory; Denver, CO) and SGS-AXYS (Sidney, BC, Canada). Concentration, surrogate recovery, and blank results are presented within.

Per- and polyfluoroaklyl substances (PFAS) of are of interest due to their persistence and ubiquity in the environment and their potential health and environmental effects. While these compounds have been well studied in the past 10 years, little is known about PFAS in oil and gas produced waters, which are voluminous and have the potential to impact the environment through surficial...

Concentrations of a group of per- and polyfluoroalkyl substances (PFAS) were measured in coastal waters around the island of Oahu, Hawai'i in 2019 and 2020 to provide a measure of exposure to resident fish species commonly harvested for human consumption. These contaminants were sampled using the polar organic chemical integrative sampler (POCIS) which allows for the determination of the...

Samples were collected for a comparison method development study with the University of Minnesota and the U.S. Geological Survey (USGS) National Water Quality Laboratory (NWQL) in Lakewood, Colorado. Widely used liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods fail to capture large fractions of total organofluorine in environmental samples confounding the assessment and...

This data release provides concentration results for per- and polyfluoroalkyl substances (PFAS) collected by volunteer community members, in tapwater samples from 83 private residences, in select areas within the United States. Samples were collected July 1, 2023, through November 10, 2023. Samples were analyzed at the U.S. Geological Survey National Water Quality Laboratory (NWQL) in...

This metadata record contains one table and one shapefile with results from field sampling at locations of groundwater discharge (seeps) identified by autonomous boat survey at the Lower Darby Creek Area (LDCA) Superfund Site, near Folcroft, Pennsylvania, in 2024. Included in the dataset are (1) PFAS concentrations, volatile organic compound (VOC) concentrations, cations/trace metals...

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...

This data set is from a study examining the flow of per- and polyfluoroalkyl substances (PFAS) through food webs. The data are PFAS concentrations in gastrointestinal contents of tree swallows.

Accurate maps of habitat availability for Greater Sage-grouse (Centrocercus urophasianus) across broad extents are of paramount importance to conservation efforts in sagebrush ecosystems across the Great Basin, particularly for habitat assessments and mitigation efforts. However, the ability to model sage-grouse habitat at fine spatial scales necessary for microhabitat assessment is...

This dataset represents the date and related identification number for each guano sample collected from the western small-footed bat (Myotis ciliolabrum) captured at Chaco Culture National Historical Park, El Malpais National Monument and El Malpais National Conservation Area, Mesa Verde National Park, Pecos National Historical Park, Guadalupe Mountains National Park, and Capulin Volcano...

This data release provides maps of estimated performance metrics for the remotely sensed evapotranspiration (ET) models within the OpenET ensemble, at the scale of the conterminous U.S. (CONUS). It also provides relative weight maps for each of the ensemble models that can be used to produce performance-weighted ensemble estimates. These maps are provided at a 4 kilometer spatial...
