Data in this release include groundwater parameters, including groundwater level, temperature, pH, dissolved oxygen, turbidity, and specific conductance, collected during the 2019-2020 water sampling and comparison data from prior, 1999-2000 sampling of the same wells. The 23 wells used for sampling were identified and sampled previously by the USGS National Water-Quality Assessment Program, starting in 1999, to assess the occurrence of a variety of inorganic and organic contaminants in the GM-BVA. Sampled wells were from parts of the GM-BVA in Butler, Champaign, Clark, Greene, Hamilton, Miami, Montgomery, Shelby and Warren counties in the Great Miami River, Little Miami River, and Whitewater River Basins.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9J7H3LB", "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.6102eb24d34ef8d7055eb3e4.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_6102eb24d34ef8d7055eb3e4", "keyword": ["Butler County", "Champaign County", "Clark County", "Great Miami River", "Greene County", "Hamilton County", "Little Miami River", "Miami County", "Montgomery County", "Shelby County", "State of Ohio", "USGS:6102eb24d34ef8d7055eb3e4", "United States of America", "Warren County", "Whitewater River", "groundwater quality", "hydrogeology", "water sampling"], "modified": "2023-03-09T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-84.8000, 39.2500, -83.6900, 40.2100", "theme": ["geospatial"], "title": "Groundwater levels and field-determined groundwater-quality characteristics from the Great Miami buried-valley aquifer, Southwestern Ohio, 1999, 2000, 2019, and 2020"}
