【 摘 要 】

Lawrence Berkeley National Laboratory (LBNL), in collaboration with the US Bureau of Reclamation and the Panoche Water District, is conducting a pilot-scale test of the viability of land application of selenium (Se)-enriched San Luis Drain (SLD) sediments. Local land disposal is an attractive option due to its low cost and the proximity of large areas of available land. Two modes of disposal are being tested: (1) the application to a nearby SLD embankment, and (2) the application to and incorporation with nearby farm soils. The study of these options considers the key problems which may potentially arise from this approach. These include disturbance of SLD sediments during dredging, resulting in increased downstream Se concentrations; movement of the land-applied Se to the groundwater; increased exposure to the biota; and reduced productivity of farm crops. This report describes field and laboratory activities carried out from 1998 through November 2000, as well as the results of these investigations.
