San Francisco Bay Area National Urban Runoff Project. Demonstration of Non-Point Source Pollution Management on Castro Valley Creek: Executive Summary

摘要

This report presents the results and conclusions from an EPA-sponsored nonpoint source pollution management project on Castro Valley Creek in Castro Valley, CA, designed to correlate street cleaning and urban runoff water quality. The study area was a suburban 1,542-acre watershed in the San Francisco Bay region. To demonstrate the relationship between street cleaning and runoff, the project was designed to measure the following: (1) street cleaning effectiveness (2) street surface pollutant loadings and (3) runoff water quality. Data were analyzed to correlate street surface pollutant loadings before rain events with changes in runoff water pollution mass yields.
