a) Indicators of PCB and Hg sources

b) Stormwater pump stations GIS

c) Soil, dust, and drop inlet sediment Hg and PCB concentrations

d) SFBay Watershed Boundaries

The goal of the RMP modeling strategy is to develop a capacity to predict the effect of different management alternatives on loads from watersheds, the recovery of contaminated areas on the Bay margin, threats from emerging contaminants, and the recovery of the Bay as a whole. This capacity will be gained through the development of conceptual and numeric models of the physical, chemical, and biological processes governing the fate of pollutants of concern in San Francisco Bay and its associated watersheds.

The Small Tributaries Loading Strategy (STLS) is overseen by the Sources, Pathways, and Loadings Workgroup. It focuses on loadings from small tributaries (the rivers, creeks, and storm drains that enter the Bay downstream of Chipps Island), in coordination with the Municipal Regional Permit for Stormwater (MRP). It aims to refine pollutant loading estimates for future TMDL and management decisions, identify the highest priority small tributaries for cleanup, and evaluate the best actions for small tributary management.
