Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Per- and polyfluoroalkyl Substances in Drinking Water at Select Public Water Systems in West Virginia, 2022 Per- and polyfluoroalkyl Substances in Drinking Water at Select Public Water Systems in West Virginia, 2022
These data were collected to understand the occurrence of per- and polyfluoroalkyl substances in drinking water samples at public water systems identified to have perfluorooctanoic acid or perfluorooctane sulfonic acid above laboratory reporting levels in previously collected raw-water samples, and provide a review of the analytical results. The West Virginia Department of Health and...
Geochronological Data for the Deep Creek paleoseismic site, Wasatch fault zone, Utah Geochronological Data for the Deep Creek paleoseismic site, Wasatch fault zone, Utah
This data release includes geochronological data for a natural exposure of the Wasatch fault, Utah at the Deep Creek site (39.507462?, -111.861790?). Laboratory data include 11 optically stimulated luminescence (OSL) ages for quartz, 23 charcoal radiocarbon ages, and 342 portable OSL (bulk luminescence) measurements. The radiocarbon and luminescence samples were collected November 2019...
Data Release for Luminescence: Construction and modification of debris-flow alluvial fans as captured in the geomorphic and sedimentary record: examples from the western Sangre de Cristo Mountains, south-central Colorado Data Release for Luminescence: Construction and modification of debris-flow alluvial fans as captured in the geomorphic and sedimentary record: examples from the western Sangre de Cristo Mountains, south-central Colorado
The following report summarizes the dating results from the San Luis Valley-Pioneer Fan 2017-2019 dating project. Within this report, we detail the methodology used by the USGS Luminescence Geochronology Laboratory to obtain ages including sample preparation methods, luminescence measurement, equivalent dose determination, and dating-related calculations. We recommend that this report be...
