Quality control samples (2 blanks and 1 replicate) were also collected to assess data reliability and precision. Samples were submitted to the USGS National Water Quality Laboratory in Denver, Colorado, and were analyzed for per- and polyfluoroalkyl (PFAS) substances in late 2022 and results provided in April of 2023. PFAS were detected in 16 of the 19 groundwater monitoring wells and in all 3 surface water sites sampled.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9W1TPNF", "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.64baf359d34e70357a2d3263.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_64baf359d34e70357a2d3263", "keyword": ["Illinois", "McHenry County", "PFAS", "USGS:64baf359d34e70357a2d3263", "contamination and pollution", "environment", "groundwater quality", "surface water quality"], "modified": "2023-12-07T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-88.9014, 41.9636, -88.0884, 42.5000", "theme": ["geospatial"], "title": "Reconnaissance of Per- and Polyfluoroalkyl Substances (PFAS) in Selected Groundwater and Surface Water Sites in McHenry County, Illinois, 2020"}
