| Abstract: | Nutrient and organic compound data from the U.S. Geological Survey and the U.S. Environmental Protection Agency STORET data bases provided information for development of a preliminary conceptual model of spatial and temporal ground- water quality in the upper Snake River Basin. Water from domestic wells contained the highest median nitrate (nitrite plus nitrate as nitrogen) concen- trations; water from industrial and public-supply wells contained the lowest. Nitrate concentrations decreased with increasing well depth, increasing depth to water (unsaturated thickness), and increasing depth below water table (saturated thickness). Nitrate concentrations were statistically higher in areas of irrigated agriculture than in areas of dryland agriculture and rangeland. Concentrations increased in areas north of Burley and northwest of Pocatello between 1980 and 1990. The following organic compounds were detected in ground water in the upper Snake River Basin: cyanazine, 2,4-D, DDT, dacthal, diazinon, dichloropropane, dieldrin, malathion, and metribuzin. Of 211 wells sampled for organic compounds, water from 17 contained detectable concentrations. |
