Combined Sewer Overflow Toxic Pollutant Study

摘要

The purpose of this study is to document the occurrence, concentration, mass, and source of priority toxic pollutants in combined sewer flows (CSF). CSF, combined sewer overflow, first flush flow, runoff, and precipitation samples were collected in eight drainage areas and analyzed for specified conventional and nonconventional pollutants and for priority toxic pollutants. Twenty-two storm events were sampled. Background dry weather flow, tap water, and sediment samples were also collected in the eight drainage areas and analyzed for the same pollutants that the wet weather samples were analyzed for.
