Stormwater runoff in a rapidly urbanizing region was analyzed for organic contamination to compare impervious and pervious surfaces. Total petroleum hydrocarbons (TPH) ranged between 5 and 277 mg/L, with impervious surfaces showing, on average, greater TPH concentrations. Pyrene and fluoranthene were identified in all impervious stormwater samples. Sediments from receiving waters also contained pyrene and fluoranthene. Runoff samples had concentrations in the range of 11-191 mu g/L. Sediment samples ranged from 2.3 x 10(1)-1.3 x 10(4) mu g/kg. Results from this study are useful for identifying major urban contaminants and understanding the role of pervious surfaces in filtering urban contaminants.
