USGS Scientific Invesigations Report 2012–5068  - Reconnaissance of Contaminants in Selected Wastewater-Treatment-Plant Effluent and Stormwater Runoff Entering the Columbia River, Columbia River Basin, Washington and Oregon, 2008

Table 9. Anthropogenic organic compounds detected in unfiltered wastewater-treatment-plant effluent, Columbia River Basin, Washington and Oregon, 2008–09. 

[Station names are shown in table 2. Concentrations reported in micrograms per liter. See table A2 for a listing of anthropogenic organic compounds analyzed and their reporting limits. Present, presence is verified, but concentration is not quantified; sometimes the reporting limit for an individual sample is raised because of matrix interference, these instances of non-detection are shown as less-than (<) the raised reporting limit. Abbreviations: ND, not determined because of matrix interferences; E, estimated; –, not detected]
