GAMA-PBP is a cooperative program between the U.S. Geological Survey and the California State Water Resources Control Board. \nThis data release contains data for samples collected from May 2019 through December 2022 and includes revisions \nto earlier data (Kent, 2021) that were either screened or removed after analysis of quality-control data. Please see the quality-control and other \ndescriptions of the data in the processing steps in the xml file. Subsequent updates will include data for samples collected after \nDecember 2022. Data are also publicly available for download from Jurgens and others (2018).\nThe dataset consists of 4 tables. \nTable 1 lists the names and abbreviations of the twenty-eight PFAS constituents analyzed. \nTable 2 contains information about each site visited, including location and well depth information. \nTable 3 contains results for each PFAS constituent analyzed and includes quality-control sample results where applicable. \nTable 4 contains a list of every sample collected at each site and has a summary of all the PFAS detections for each sample.\nThis data release supercedes previous PFAS data release versions reported by Kent (2021).\nVersion 2.0 of the previous data release (Kent, 2021) contained data for samples collected from May 2019 through June 2021. Data from\nKent (2021) is available upon request from the authors of this data release.\nReferences:\nKent, R.H., 2021, Data sets for: Sampling for Per-and Polyfluoralkly Substances (PFAS) by the GAMA Priority Basin Project (GAMA-PBP)(2019-2021) (ver. 2.0, October 2021): U.S. Geological Survey data release, https://doi.org/10.5066/P92IPRJD.\nJurgens, B.C., Jasper, M., Nguyen, D.H., and Bennett, G.L., 2018, USGS CA GAMA-PBP Groundwater Quality Results--Assessment and Trends: U.S. Geological Survey website, available at https://doi.org/10.5066/P91WJ2G1.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9ETQ00R", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.641b44f8d34e4c337f0c31d7.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_641b44f8d34e4c337f0c31d7", "keyword": ["Butte County", "California", "Colusa County", "Del Norte County", "Fresno County", "Humboldt County", "Imperial County", "Kern County", "Kings County", "Lassen County", "Los Angeles County", "Madera County", "Marin County", "Mariposa County", "Mendocino county", "Merced County", "Modoc County", "Monterey County", "Napa County", "Nevada County", "Orange County", "Placer County", "Plumas County", "Riverside County", "Sacramento County", "San Bernardino County", "San Diego County", "San Joaquin County", "San Luis Obispo County", "Santa Barbara County", "Santa Cruz County", "Shasta County", "Sierra County", "Siskiyou County", "Solano county", "Sonoma County", "Stanislaus County", "Tehama County", "Trinity County", "Tulare County", "USGS:641b44f8d34e4c337f0c31d7", "United States", "Ventura County", "Western United States", "Yolo County", "Yuba County", "biota", "environment", "groundwater", "water quality", "water sampling"], "modified": "2023-07-03T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-124.5076, 32.4256, -113.4888, 42.0665", "theme": ["geospatial"], "title": "Data for Per- and Polyfluoroalkyl Substances (PFAS) in groundwater samples collected by the California Groundwater Ambient Monitoring and Assessment Priority Basin Project, 2019-2023"}
