This report from the Regional Monitoring Program for Water Quality in San Francisco Bay features articles on the four major pathways by which pollutants enter the Bay: municipal wastewater, industrial wastewater, stormwater, and dredging and dredged sediment disposal.  Each article provides a basic introduction to the pathway and discusses the regulatory framework, recent findings, and future challenges.  The report also includes some of the latest highlights from monitoring of important parameters such as nutrients, emerging contaminants, mercury, PCBs, and selenium.
