Ground-water conditions in the eastern part of Michaud Flats, Fort Hall Indian Reservation, Idaho

Hydrogeology of eastern Michaud Flats, Fort Hall Indian Reservation, Idaho

“…Between December 1981 and January 1982, water samples for chemical analyses were obtained from three wells and two springs previously sampled (Jacobson, 1982) and from two observation wells drilled by the U.S. Geological Survey. Results of the chemical analyses are given in table 2.…”

“…Results of the first phase described geohydrologic and water-quality conditions in the vicinity of a large industrial complex that processes phosphate ores in the eastern Michaud Flats area on and near the Fort Hall Indian Reservation (Jacobson, 1982). …”

Reconnaissance investigation of water quality, bottom sediment, and biota associated with irrigation drainage in the American Falls Reservoir area, Idaho, 1988-89

“…Water resources in the American Falls Reservoir area have been studied by Swendsen (1924); Stearns and others (1938); Stewart and others (1951); West and Kilburn (1963); Mundorff and others (1964);Mundorff (1967);Castelin (1974); Balmer and Noble (1979);Jacobson (1982Jacobson ( , 1984; Kjelstrom (1986Kjelstrom ( , 1988; and J.M. Spinazola and others (U.S. Geological Survey, written commun., 1988).…”

“…Selenium concentrations were determined for 20 ground-water samples and 5 spring samples in the Michaud Flats area along the southeastern corner of the reservoir. Selenium concentrations in these samples ranged from 0 to 4 ug/L (Jacobson, 1982). Frenzel and Jones (1985) listed water-quality data collected from a tributary to the Portneuf River as part of a nonpoint source pollution study.…”

National water summary 1983: Hydrologic events and issues

“…Some water from shallow aquifers near Boise (Parliman, 1982a(Parliman, , 1983a, in the Rathdrum Prairie area (Parliman and others, 1980) and in several areas in eastern and south-central Idaho (Parliman, 1982b(Parliman, , 1983b contains bacteria and a variety of naturally dissolved minerals, such as fluoride, sulfate, chloride, or iron, that exceed limits for drinking water (U.S. Environmental Protection Agency, 1976. A shallow aquifer underlying phosphate-processing plants near Pocatello contains high concentrations of arsenic and heavy metals (Jacobson, 1982). Radioactive waste water from a nuclear chemical-processing plant at the Idaho National Engineering Laboratory (Butte County) is being injected into the Snake Plain aquifer (Robertson and others, 1974).…”
