Pollutant Loadings to Stormwater Run-Off From Highways: The Impact of a Freeway Sweeping Program.

摘要

The Wisconsin Department of Transportation is required to control the quality of storm water runoff from the state highway system in response to the EPA National Pollution Discharge Elimination System and the Wisconsin Department of Natural Resources regulations. A method to control roadway storm water runoff pollutants on urban freeways is by the use of street sweepers to remove pollutants before they enter storm water runoff and runoff control structures. This study evaluates the effectiveness of an improved highway sweeping program using a high efficiency sweeper as a best management practice (BMP) for reducing pollutants in urban highway storm water runoff.
