摘要

Three areas, chosen to represent a range of agricultural practices and applied pesticides, were studied to document whether agricultural pesticides are being transported into the soil and shallow ground water in irrigated areas of Montana. Analytical scans for triazine herbicides, organic-acid herbicides, and carbamate insecticides were performed on soil and shallow ground-water samples. The results indicate pesticide residue in both types of samples. All detectable concentrations of pesticides in ground water were less than health-advisory limits established by the U.S. Environmental Protection Agency. The presence of residue of two pesticides in soil samples and three soluble pesticides in ground-water samples indicates that irrigated agricultural areas of Montana might be susceptible to the transport of soluble pesticides through permeable soils, to the shallow ground-water system.
