1 Engberg, R. A.; Sylvester, M. A. 1993. Concentrations, distribution, and sources of selenium from irrigated lands in Western United States. Journal of Irrigation and Drainage Engineering, 119(3):522-536.
(Location: IWMI-HQ Call no: PER Record No: H012852)
Concentrations, distribution, and sources of selenium from irrigated lands were studied between 1986 and 1990 at 20 reconnaissance project areas in 17 western states under the Department of Interior's National Irrigation Water Quality Program. Samples of water, bottom sediment whole-body fish, and bird livers for analysis of selenium concentrations were collected before, during, and after irrigation season from streams, canals, lakes, and ground water in each project area. Cretaceous-age marine shales probably are the original sources for selenium in 16 of the 20 areas studied. In several areas, evaporative concentration of applied irrigation water and drainage of this water to wetlands, canals, streams, and lakes appears to be responsible for elevated concentrations of selenium.
