Critical Zone Processes Across Landscapes

Integrated Studies of the California Geochemical Landscape

Task Objectives

This task continues the California Pilot Study that was started under the Geochemical Landscapes project. The Sacramento Valley is important for its economic impacts to agriculture and as a major water source to California. It's major city, Sacramento, is the state capitol. There are complex sources of sediment to the valley, some of which contain potential toxic materials in adjacent mountain ranges. These include asbestos, arsenic, mercury, and chromium. We are characterizing the potential impact of these constituents to valley sediments and the local population.

Task objectives are to determine the geologic, anthropogenic, hydrologic, and geomorphic controls on the soil geochemistry of the Sacramento Valley and to research the impact of soil constituents and dust derived from the soil on human health.

Planned Work

The focus will be on a collaborative study with the California Air Resources Board and the University of Wisconsin to characterize the mineralogy and composition of dust in the southern Sacramento Valley. Collaborative research will be continued with the USGS Sacramento Water Science Center on mercury in soil and on controls on groundwater chemistry in the Sacramento Valley. The application of geophysical methods to identify potential sources of asbestos and chromium will continue to be evaluated.
