Concentrations also were measured every 2 days at a subset of 8 of the sites, all located in Missouri. Glyphosate was detected more frequently in urban streams than in agricultural streams, and at concentrations similar to those in streams with high agricultural land use in the watershed.  In contrast, atrazine was detected more frequently and at higher concentrations in agricultural streams than in urban streams. This data release provides watershed characteristics and 2013 glyphosate and atrazine compound concentrations used in the analysis presented in the journal article \u201cSimilarities and differences in temporal fluctuations in glyphosate and atrazine in small Midwestern streams (USA) during the 2013 growing season,\u201d by BJ Mahler, PC Van Metre, TE Burley, KA Loftin, MT Meyer, and LH Nowell, http://dx.doi.org/10.5066/F7SN073J.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://dx.doi.org/10.5066/F7SN073J", "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.57bb51ece4b03fd6b7dd04de.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_57bb51ece4b03fd6b7dd04de", "keyword": ["2013", "August", "Corn Belt", "ELISA", "Illinois", "Indiana", "Iowa", "July", "June", "Kansas", "Kentucky", "May", "Minnesota", "Missouri", "Nebraska", "Ohio", "South Dakota", "USGS:57bb51ece4b03fd6b7dd04de", "United States", "Wisconsin", "atrazine", "glyphosate", "herbicide", "river", "spring", "spring flush", "stream", "summer"], "modified": "2020-08-27T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-99.987241, 36.433529, -81.378301, 45.381318", "theme": ["geospatial"], "title": "Concentrations of glyphosate and atrazine compounds in 100 Midwest United States streams in 2013"}
