Abstract
Roadways and highways have been identified as a source of significant contribution of pollutants to water bodies and a degradation factor to coastal waters in the United States (EPA, Guidance Specifying Management Measures for Sources of Nonpoint Pollution in Coastal Waters, 1993). Sediment, litter, vegetative debris and heavy metals are constantly being deposited on roadways. These roadway pollutants emitted by vehicles and anthropogenic sources are deposited on pavement surfaces and transported to nearby water bodies by surface runoff caused by rain. The purpose of this project is to analyze the current street sweeping program implemented by the County of San Diego. Street sweeping is a source control intended to reduce vehicular pollution on roadways prior to release into regional water bodies within San Diego County. For our study we concentrated on copper loading from vehicle’s brake pads traveling through roadways within rural communities. Collected data from several cities and counties, accredited literature reports, scholarly texts, and field observations will be used to examine the effectiveness of the current source control measure. By evaluating the effectiveness of street sweeping practices, recommendations will be given to the County of San Diego sweeping program, based on the findings of this project.
