Demonstration of Nonpoint Pollution Abatement Through Improved Street Cleaning Practices

摘要

A presentation is given of the results and conclusions from the EPA-sponsored demonstration study of nonpoint pollution abatement through improved street cleaning practices. An important aspect was the development of sampling procedures to test street cleaning equipment performance in real-world conditions. Other areas explored in this study include: (1) accumulation rate characteristics of the various pollutants associated with street dirt; (2) runoff flow characteristics, concentrations and total mass yields of monitored pollutants in runoff, and street dirt removal capabilities and effects on deposition in the sewerage for various kinds of storms; (3) costs and labor effectiveness of street cleaning, runoff treatment, and combined runoff and wastewater treatment; and (4) results of a special study of airborne dust losses from street surfaces.
