Description: A well sampling survey was conducted to determine the presence of fenamiphos, fenamiphos sulfoxide, and fenamiphos sulfone in ground water. Wells were sampled in areas where use of fenamiphos coincided with areas of previous contamination by other pesticides, This was possible because fenamiphos is a restricted use pesticide so a spatial record of use was available and the CDFA’s Well Inventory Data Base contains spatial locations of historical pesticide detections in well water. Twenty-four wells were sampled in 16 sections in Fresno County, 12 wells were sampled in 8 sections in San Joaquin County and 5 wells were sampled in 3 sections in Kern County. No residues of fenamiphos or its sulfoxide and sulfone metabolites were detected in any of the samples.
