Pollutants in storm water runoff from metal plating facilities, Los Angeles, California

摘要

This research evaluated storm water runoff water quality constituent data collected by industrial facilities under California's 1992 General Industrial Storm Water NPDES Permit. Data for 13 constituents were evaluated for a sample of 130 metal plating facilities In Los Angeles County, reported over a 3-year period. Results are intended as a screening level determination of several factors: Proportion of facilities detecting the constituents; their concentrations in a single-industry, single-region set of facilities; and possi- Ble trends over time.
