Copper Sources- P2/BMPs

Publicly owned treatment works (POTWs) and municipal storm drains convey copper from various sources to San Francisco Bay. In order to identify effective pollution prevention best management practices (BMPs), the sources of copper that reach these two major conveyance systems have been studied since the 1990's. In addition to these two major conveyance systems, copper also reaches the Bay from some specialized shoreline activities.

The list of copper sources and effective BMPs for their control are arranged according to the three ways they are conveyed to the Bay: municipal stormwater runoff, discharges to POTWs and shoreline activities. Each copper source listed is linked to a separate page that contains information about how copper is released, BMPs which control copper releases and additional links to other information sources and websites.

Currently, limited data is available on the amount of copper contributed to the Bay from most of the sources; nor is quantitative information available on the likely reductions in copper that will result from the implementation of specific BMPs. The use of many of these BMPs is justified because they reduce not only copper, but also other pollutants of concern. In some cases, these BMPs are implemented primarily to address pollutants other than copper.
