This report summarizes the principal findings of the Cache Creek, California, components of a project funded by the CALFED Bay-Delta Program entitled "An Assessment of Ecological and Human Health Impacts of Mercury in the Bay-Delta Watershed." A companion report summarizes the key findings of other components of the project based in the San Francisco Bay and the Delta of the Sacramento and San Joaquin Rivers. These summary documents present the more important findings of the various studies in a format intended for a wide audience. For more in-depth, scientific presentation and discussion of the research, a series of detailed technical reports of the integrated mercury studies is available at the following website: < http://loer.tamug.tamu.edu/calfed/ >.
The overall study was a scientific cooperation and collaboration among several federal and state agencies and universities and one commercial laboratory. These agencies included the U.S. Geological survey (USGS), the U.S. Fish and Wildlife Service, the California Department of Fish and Game, the California Central Valley Regional Water Quality Control Board, the California Geological Survey, the University of California Davis, the San Jose State University Foundation, and Frontier Geosciences, Inc.
