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 13. Halogenated compounds detected in solids filtered from wastewater-treatment-plant effluent, Columbia River Basin, Washington and Oregon, 2008–09. 

[Station names are shown in table 2. Concentrations reported in nanograms per liter. See table A1 for a listing of halogenated 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: L, liter; –, not detected; ND, not determined because of poor compound recoveries]
