Geological Survey, in cooperation with the U.S. Environmental Protection Agency, \ndeveloped a numerical ground-water-flow model, using MODFLOW-2000, to simulate \nground-water flow in the Pohatcong Valley including the area within the Pohatcong Valley \nGround Water Contamination Site. In 1978, the chlorinated solvents trichloroethene (TCE) \nand tetrachloroethene (PCE) were detected in thePohatcong Valley in production wells in \nWashington Borough and Washington Township, Warren County, New Jersey. Subsequent \ninvestigation revealed that many domestic wells in Washington and Franklin Townships \nalso were contaminated, and in 1989 the Pohatcong Valley Ground Water Contamination \nSite was added to the U.S. Environmental Protection Agency (USEPA) National Priority List. \nA remedial investigation, by the USEPA and CH2M Hill with technical assistance from the \nU.S. Geological Survey (USGS), was begun in 1999.  The simulation of ground-water flow in \nthe Pohatcong Valley described here was conducted by the USGS in cooperation with the \nUSEPA. The ground-water-flow model, using MODFLOW-2000 and the particle\u2013tracking \nprogram MODPATH, estimated flow paths of groundwater from known sources of contamination \nin Washington Borough and tested possible site contamination remediation alternatives. Five \nground-water remediation alternatives (GW2a, GW2b, GW3a, GW3b, and GW4b) were \nsimulated. In addition, a 10-year solute transport simulation was conducted, using the USGS \ngroundwater-transport process, to illustrate the potential for dispersion to increase the width of \nthe solute plume.  This USGS data release contains all of the input and output files for the \nsimulations described in the associated model documentation report \n(https://doi.org/10.3133/sir20065269).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9ES6UPO", "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.d322fc64-ab02-4c44-8fa6-05d17d58a953.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_d322fc64-ab02-4c44-8fa6-05d17d58a953", "keyword": ["Groundwater", "Groundwater Model", "InlandWaters", "MODFLOW-2000", "MODPATH4", "New Jersey", "Pohatcong Valley", "Solute transport", "USGS:d322fc64-ab02-4c44-8fa6-05d17d58a953", "Warren County", "environment", "geoscientificInformation", "inlandWaters", "particle tracking", "usgsgroundwatermodel"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-75.223078, 40.612520, -74.898243, 40.831297", "theme": ["geospatial"], "title": "MODFLOW-2000 and MODPATH4 used to simulate groundwater flow and contaminant transport in the Pohatcong Valley, Warren County, New Jersey"}
