Abstract:

An arsenic reconnaissance study was made from August through November 1974 in the Dry Creek basin in northern California where the U.S. Army Corps of Engineers proposes to construct Warm Springs Dam. The purpose was to determine the extent of any potential arsenic problems that may affect Lake Sonoma which would form behind the dam. Samples of sediment, water, and biota were collected and analyzed for arsenic content. Results indicate that arsenic presents a potential problem only in the Little Warm Springs Creek area where samples of geothermal water contained 140 micrograms of arsenic per litre of water.
