Selenium concentrations in waters tributary to and in the vicinity of the Kesterson National Wildlife Refuge, Fresno and Merced counties, California
Year: 1984
Type: report
Abstract: Analyses were made for selenium in waters and other materials of the Kesterson National Wildlife Refuge.Analyses were also made of source agricultural drainage waters from the San Luis Drain discharged into the refuge, and surrounding irrigation supply and return waters.Selenium concentrations range from 140 to 1,400 micrograms per liter (ug/L) in irrigation drain waters supplied to the San Luis Drain.The selenium supplied to the Kesterson National Wildlife Refuge is to a small extent precipitated in sodium sulfate (thenardite) but a higher concentration was found in an algal mat.Most other waters of the area contain less than detectable (<2 ug/L) concentrations of selenium.-2 Oxidation of organic matter and reduction of selenate (SeO4 ) to selenite -2 (SeO3 ) were found to be necessary for a quantitative analysis of total selenium.
