Data for East Coast and Upper Midwest PFAS study sites Data for East Coast and Upper Midwest PFAS study sites
Concentrations of Total40 per- and polyfluoroalkyl substances (PFAS), perfluorooctane sulfonate (PFOS), perfluorohexane sulfonate (PFHxS), and Total13 PFAS were consistently higher at the AFFF sites compared to the two East Coast reference sites in tree swallow eggs, nestlings, and diet by as much as a factor of 40 times higher. Sites in the Upper Midwest with other PFAS sources also had
Minerals Yearbook, volume III, Area Reports — International: 2019 country chapters, table 1, production of mineral commodities Minerals Yearbook, volume III, Area Reports — International: 2019 country chapters, table 1, production of mineral commodities
This data release contains the compilation of country level mineral commodity production data extracted from Table 1 within all published 2019 international chapters in the U.S. Geological Survey's annual publication Minerals Yearbook Volume III: Area Reports — International. Individual Minerals Yearbook country chapters are published independently from the complete volume as "Advanced...
Sorption Coefficients (Kd) for Perfluorooctanoic acid (PFOA) and Perfluorooctanesulfonic acid (PFOS), and supporting soil properties at a 250-meter resolution, based on 30-meter resolution data from the Polaris Soils database Sorption Coefficients (Kd) for Perfluorooctanoic acid (PFOA) and Perfluorooctanesulfonic acid (PFOS), and supporting soil properties at a 250-meter resolution, based on 30-meter resolution data from the Polaris Soils database
Per- and polyfluoroalkyl substances (PFAS) chemicals are known to strongly sorb onto soils when being transported downward through the vadose zone. The degree to which this sorption occurs depends on the length of the specific PFAS molecular chain and the properties of the soil. The properties with greatest influence on the soils PFAS sorption potential are percent silt and clay, and...
Detailed Mapping of the 1983 Borah Peak Earthquake Surface Rupture (Idaho, USA) Using a High-Resolution Digital Terrain Model Derived from 2019 Lidar Data Detailed Mapping of the 1983 Borah Peak Earthquake Surface Rupture (Idaho, USA) Using a High-Resolution Digital Terrain Model Derived from 2019 Lidar Data
In this work, we refined and expanded the coseismic surface rupture map of the 1983 M6.9 Borah Peak earthquake coseismic rupture mapping at a scale of 1:500. While earlier work (DuRoss et al., 2019; Bello et al., 2020, 2021) used structure-from-motion (SfM) methods to construct digital elevation models (DEMs) derived from small uncrewed aerial systems (sUAS or drone) imagery, the...
Whole-Rock Geochemistry for Eocene Volcanic Rocks of the Toutle 7.5-Minute Quadrangle, Washington Whole-Rock Geochemistry for Eocene Volcanic Rocks of the Toutle 7.5-Minute Quadrangle, Washington
This data release contains geochemical data for 52 rock samples collected by Russell C. Evarts and colleagues from 1992 to 1999 to support geologic mapping of the Toutle 7.5-minute quadrangle in southwest Washington. Fifty samples were analyzed in analytical laboratories of the U.S. Geological Survey (USGS) and three samples were analyzed at the Peter Hooper GeoAnalytical Laboratory at...
