Eurasian watermilfoil, an aquatic invasive weed, has been identified recently at a number of sites in western Nevada and northeastern California, including Lake Tahoe. Because Eurasian watermilfoil is easily spread by fragments, transport on boats an

Pentachlorophenol (PCP) was applied to loamy sand and sandy clay loam soils to determine the effect of upward evaporative flux on the rates of photolytic loss. Subirrigated soil columns were irradiated by ultraviolet lamps or sunlight to measure rela

Photolysis in soils is effectively limited to the top 0.5 mm of the soil surface. Consequently, processes that move contaminants to this sunlight-irradiated zone may have a significant impact on the degree of photolysis in soils. The effect of upward
