The San Francisco Estuary Institute has been collecting water, sediment and tissue samples from the San Francisco Bay and tributaries since 1993. These samples are analyzed for ancillary parameters, trace metals and trace organics. Each year a summary of the year's sampling events is published in the Regional Monitoring Program’s Annual Monitoring Results. The results and associated graphics can be accessed using the Contaminant Data Display & Download (CD3) tool.
