Data were collected over this time frame to determine seasonal and annual changes in surface water estrogenicity.Estrogen is reported as estrogen equivalents (EEQ) as determined by a bioluminescent yeast estrogen screen.  A total of 193 grab water samples were collected during this time of which 41% had EEQ above the limit of detection. The maximum estrogen equivalents (EEQ) measured was 5.44 ng EEQ/ L, while the median concentration was 0.44 ng/L. POCIS samplers were deployed at a number of sites to determine time-weighted estrogenicity between 2014 and 2017. A total of 150 POCIS samples were deployed over this time of which 77% had EEQ above the limit of detection.. The maximum estrogen equivalents (EEQ) measured was 12 ng EEQ/ POCIS.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9PQA90O", "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.61af76fcd34eb622f69b11f7.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_61af76fcd34eb622f69b11f7", "keyword": ["USGS:61af76fcd34eb622f69b11f7", "bioassay", "endocrinology", "environmental health", "estrogenicity", "lakes", "rivers", "streams"], "modified": "2022-03-07T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-79.8308, 39.724964, -74.77844028, 41.971434", "theme": ["geospatial"], "title": "Estrogen equivalents of surface water in Pennsylvania, 2012-2017"}
