In urbanized areas, wastewater treatment plants (WWTPs) are critical facilities for collecting and reducing the amounts of wastewater contaminants (WWCs) that ultimately discharge to rivers, coastal areas, and groundwater. Most WWTPs use multiple methods to remove contaminants from wastewater. These include physical methods to remove solid materials (primary treatment), biological and chemical methods to remove most organic matter (secondary treatment), advanced methods to reduce the concentrations of various contaminants such as nitrogen, phosphorus and (or) synthetic organic compounds (tertiary treatment), and disinfection prior to discharge (Metcalf and Eddy, Inc., 1979). This study examined the extent to which 114 organic WWCs were removed by each of three WWTPs, prior to discharge to freshwater and marine ecosystems, in a rapidly developing area in northwestern Washington State. Removal percentages for each WWC were estimated by comparing the concentrations measured in the WWTP influents with those measured in the effluents. The investigation was carried out in the 700-mi2Stillaguamish River Basin, the fifth largest watershed that discharges to Puget Sound (fig. 1).", "description": "4 p.", "publisher": {"@type": "Organization", "name": "U.S. Geological Survey"}, "author": [{"@type": "Person", "name": "Moran, Patrick W. pwmoran@usgs.gov", "givenName": "Patrick W.", "familyName": "Moran", "email": "pwmoran@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-2002-3539", "url": "https://orcid.org/0000-0002-2002-3539"}, "affiliation": [{"@type": "Organization", "name": "Washington Water Science Center", "url": "https://www.usgs.gov/centers/washington-water-science-center"}]}, {"@type": "Person", "name": "Barbash, Jack E. jbarbash@usgs.gov", "givenName": "Jack E.", "familyName": "Barbash", "email": "jbarbash@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0001-9854-8880", "url": "https://orcid.org/0000-0001-9854-8880"}, "affiliation": [{"@type": "Organization", "name": "Washington Water Science Center", "url": "https://www.usgs.gov/centers/washington-water-science-center"}]}, {"@type": "Person", "name": "Wagner, Richard J. rjwagner@usgs.gov", "givenName": "Richard J.", "familyName": "Wagner", "email": "rjwagner@usgs.gov", "affiliation": [{"@type": "Organization", "name": "Washington Water Science Center", "url": "https://www.usgs.gov/centers/washington-water-science-center"}]}, {"@type": "Person", "name": "Wolanek, Michael", "givenName": "Michael", "familyName": "Wolanek", "affiliation": [{"@type": "Organization", "name": "City of Arlington, WA"}]}], "funder": [{"@type": "Organization", "name": "Washington Water Science Center", "url": "https://www.usgs.gov/centers/washington-water-science-center"}], "spatialCoverage": [{"@type": "Place", "additionalType": "country", "name": "United States", "url": "https://geonames.org/6252001"}, {"@type": "Place", "additionalType": "state", "name": "Washington", "url": "https://geonames.org/5815135"}, {"@type": "Place", "additionalType": "unknown", "name": "Stillaguamish River Basin"}, {"@type": "Place", "geo": [{"@type": "GeoShape", "additionalProperty": {"@type": "PropertyValue", "name": "GeoJSON", "value": {"type": "FeatureCollection", "features": [{"type": "Feature", "properties": {}, "geometry": {"type": "Polygon", "coordinates": [[[-122.39181518554686, 48.26491251331118], [-122.21328735351562, 48.32156041109599], [-122.11715698242188, 48.40732607972984], [-121.94961547851562, 48.46745824148332], [-121.64337158203124, 48.46108396195774], [-121.57608032226562, 48.387266208071274], [-121.61315917968749, 48.265826687750916], [-121.57882690429688, 48.20087966673982], [-121.47308349609374, 48.1367666796927], [-121.41403198242189, 48.09000531373827], [-121.4483642578125, 48.04779189160941], [-121.5252685546875, 48.09459164290992], [-121.61315917968749, 48.08358376568458], [-121.81915283203126, 48.13218411348939], [-121.98669433593749, 48.12118428591277], [-122.12677001953124, 48.189894561126884], [-122.21603393554688, 48.189894561126884], [-122.35198974609375, 48.11476663187632], [-122.36984252929688, 48.13493370228957], [-122.37396240234375, 48.167001359708934], [-122.37533569335936, 48.19904897935913], [-122.39181518554686, 48.26491251331118]]]}}]}}}, {"@type": "GeoCoordinates", "latitude": 48.27079382388319, "longitude": -121.89581193784772}]}]}
