San Francisco Bay Estuary Priority Ecosystem Study
An oblique aerial photo showing sediment disturbance and transport at Dunbarton Bridge on the San Francisco Bay, California. USGS scientists have studied pesticides that are associated with suspended sediments flushed into the Bay by rivers during high flow events.

Diverse organic and inorganic contaminants that vary
widely in their environmental behavior, sources, and toxicity enter the
San Francisco Bay estuary. Toxic substances enter the estuary in agricultural
and urban runoff and in discharges from municipal wastewater facilities
and industries. The study focuses on the movement, fate, and effect of
contaminants from a variety of agricultural, industrial, and urban sources,
such as pesticides and toxic trace elements, and on the effects of the
highly varying hydrologic conditions in river--estuarine environments.
Scientists are developing an approach to characterize the distribution
of contamination and the resulting ecological effects that will be applied
in similar environments elsewhere.
