Scientific Investigations 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, 2008–10


Table 17. Halogenated compounds detected in solids filtered from stormwater runoff, Columbia River Basin, Washington and Oregon, 2009–10.


[Station names are shown in table 3. Outfalls shown in downstream order; 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. Abbreviations: L, liter; –, not detected; ND, not determined because of poor compound recoveries; sometimes the reporting limit for an individual sample was raised because of matrix interference, these instances of non-detection are shown as less-than (<) the raised reporting limit]
