Hydrological, geochemical, and ecological characterization of Kesterson Reservoir: Annual report, October 1, 1986 through September 30, 1987

OSTI ID:7242587

Over the past two years scientists and engineers at Lawrence Berkeley Laboratory (LBL) and the Sanitary Engineering and Environmental Health Research Laboratory (SEEHRL) have investigated the effects of selenium contamination at Kesterson Reservoir. Selenium was present in food chain items at levels potentially toxic to birds by 1983. Although selenium concentrations have decreased in food chain items since drainage water inflow to the Reservoir ceased in 1986, selenium concentrations remain unacceptably high. Degradation of local groundwater resources, both from selenium contamination and accumulation of salts in near surface soils is also of concern. This report summarizes the results of a multidisciplinary program of research and monitoring activities aimed at providing a technical basis for choosing the best method for remediation of Kesterson Reservoir. 79 refs., 65 figs., 24 tabs.
