Description In May 1991, 27 wells and two field drains near Quincy were tested for 76 agricultural pesticides. One or more pesticides were detected in 26 of the wells and both drains. The compound 1,2-dichloropropane was detected most often (66 percent of sites) followed by ethylene dibromide (EDB) (62 percent of sites). The mean concentration of 1,2-dichloropropane was about 0.20 mg/L and that of EDB was about 0.017 mg/L. Dacthal (DCPAs) was detected at 55 percent of the sites during the initial sampling, but was not detected in the verification samples. EDB concentrations in nine wells and one drain exceeded the drinking water standard for public water supply systems.
