Abstract : U.S. Environmental Protection Agency (USEPA) regulations require monitoring of chlorinated phenoxyacid herbicides such as 2,4-D, 2,4,5-T, and silvex in groundwater, drinking water, and wastes. Established analytical methods are time-consuming, can be hazardous, and often yield poor recoveries in routine laboratory use. This report describes a procedure for extraction of these compounds from sediment and water using solid phase extraction with analysis by high-performance liquid chromatography. This procedure yields reproducible results with recoveries of greater than 50 percent and method detection limits well below the criteria required by USEPA. Because of the nature of the extraction, this procedure can be used with a savings in preparation time, labor, and health risk.
