This project was designed to evaluate potential land-development effects on groundwater and surface-water \nresources so that informed land-use and water management decisions can be made. The boundary of the ERWVFA \nwas developed by combining information from two data sources. The first data source was a 1:250,000-scale geologic \nmap of the Leadville quadrangle developed by Day and others (1999). The location of Quaternary sediments was used \nas a first approximation of the ERWVFA. The boundary of the ERWVFA was further refined by overlaying the geologic \nmap with Digital Raster Graphic (DRG) scanned images of 1:24,000 topographic maps (U.S. Geological Survey, 2001). \nWhere appropriate, the boundary of the ERWVFA was remapped to correspond with the edge of the valley-fill aquifer \nmarked by an abrupt change in topography at the edge of the valley floor throughout the Eagle River watershed. The \nboundary of the ERWVFA more closely resembles a hydrogeomorphic region presented by Rupert (2003, p. 8) because \nit is based upon general geographic extents of geologic materials and not on an actual aquifer location as would be \ndetermined through a rigorous hydrogeologic investigation.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9DK369Z", "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.cde4d237-a688-4527-9e42-4d754f50e096.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_cde4d237-a688-4527-9e42-4d754f50e096", "keyword": ["Brush Creek", "CFC", "Colorado", "Dotsero, CO", "Eagle County, CO", "Eagle River", "Eagle River Watershed", "Eagle, CO", "Edwards, CO", "Gypsum Creek", "Gypsum, CO", "Minturn, CO", "USGS:cde4d237-a688-4527-9e42-4d754f50e096", "VOC", "Vail, CO", "Wolcott, CO", "aquifer", "chlorofluorocarbons", "contamination", "ground water", "groundwater", "groundwater age", "inlandWaters", "logistic regression", "nitrate", "probability", "probability of groundwater contamination", "susceptibility", "volatile organic compound", "vulnerability"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-107.115526, 39.545337, -106.275574, 39.717408", "theme": ["geospatial"], "title": "Boundary of the Eagle River Watershed Valley-Fill Aquifer, Eagle County, North-Central Colorado, 2006-2007"}
