To help address the lack of data on broad contaminant exposures in private-well TW from hydrologically vulnerable (alluvial or karst) aquifers in agriculturally intensive landscapes, samples were collected in 2018-2019 from 47 northeast Iowa farms and analyzed for 437 unique organic compounds, 32 inorganic constituents, 5 in vitro bioassays, and 11 microbial assays.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9IYT37H", "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.5fad56aad34eb413d5df459c.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5fad56aad34eb413d5df459c", "keyword": ["Karst topography", "USGS:5fad56aad34eb413d5df459c", "biota", "environmental health", "groundwater", "inorganic constituents", "microbial constituents", "organic constituents", "private well", "tap water", "tapwater"], "modified": "2023-01-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-92.2852, 41.5415, -90.0879, 43.6122", "theme": ["geospatial"], "title": "Target-chemical concentrations, exposure activity ratios, and bioassay results for assessment of mixed-organic/inorganic chemical exposures in northeast Iowa private-well tapwater, 2018"}
