Table A1. Reporting limits and possible uses or sources of halogenated compounds analyzed in solids filtered from wastewater-treatment-plant effluent or stormwater runoff, Columbia River Basin, Washington and Oregon, 2008–10.
[Shading indicates a detection in wastewater-treatment-plant effluent in this study; bold type indicates a detection in stormwater runoff in this study. CAS No.: Chemical Abstract Service Registry Number® is a Registered Trademark of the American Chemical Society. CAS recommends the verification of the CASRNs through CAS Client ServicesSM. Reporting limit: Reported in nanograms; divide the reporting limit by the volume of water filtered for each sample to get the reporting limit in nanograms per liter. Possible compound uses or sources: From Steve Zaugg, U.S. Geological Survey, written commun., December 2008. Abbreviation: NA, not available]
