Four geochemical approaches were used to determine chemical reactions controlling solute concentrations in the Snake River Plain regional aquifer system: (1) calculation of a solute balance within the aquifer, (2) identification of weathered products in the aquifer frame- work, (3) comparison of thermodynamic mineral saturation indices with plausible solute reactions, and (4) comparison...

Physical, chemical, and biological characteristics of the Boise River were examined from October 1987 to March 1988 to determine whether trace elements in effluents from two Boise wastewater treatment facilities were detrimental to aquatic communities. Cadmium, chromium, hexavalent chromium, cyanide, lead, nickel, and silver concentrations in the Boise River were less than or near...

Amounts of water withdrawn and consumptively used for irrigation and other uses on the Snake River Plain were estimated to help deter- mine hydrologic effects of ground- and surface-water use. Irrigation is the largest off stream use of water on the plain. Surface-water irriga- tion began in the 1840's and increased rapidly through the early 1900's. Use of ground water for irrigation

This report presents July 1988 water quality data, principally dissolved nitrite plus nitrate (as nitrogen), and depth-to-water measurements for 60 wells in the Fort Hall Indian Reservation north of Pocatello, southeastern Idaho. Nitrogen concentrations ranged from 0.7 to 24 mg/L; the median concentration was 3.1 mg/L. Nitrogen concentrations in 11 samples exceeded the U. S...

The Groveland-Collins area near Blackfoot, Idaho, has a history of either periodic or persistent localized groundwater contamination. Water users in the area report offensive smell, metallic taste, rust deposits, and bacteria in water supplies. During 1984 and 1985, data were collected to define regional and local geologic, hydrologic, and groundwater quality conditions, and to identify...

This map report presents selected March-April 1987, water quality data, principally dissolved nitrite plus nitrate as nitrogen, and depth-to-water measurements for 118 wells in the Burley Irrigation District, south-central Idaho. Nitrogen concentrations ranged from 0.37 to 30 mg/L; the median concentration was 8.0 mg/L. Nitrogen concentrations in 19 wells equaled or exceeded the U.S...

The Idaho National Engineering Laboratory (INEL), in southeastern Idaho, is a principal center for nuclear energy development for the Department of Energy (DOE) and the U.S. Nuclear Navy. Fifty-two reactors have been built at the INEL, with 15 still operable. Extensive environmental surveillance is conducted at the INEL by DOE's Radiological Environmental Sciences Laboratory (RESL), and...

Well-construction, geologic, and water level data from 1978 to 1985 were compiled for 163 sites near Blackfoot, Idaho. Groundwater quality data were compiled for 51 sites for the period 1961-83 and for 54 sites for the period 1984-85. Data were collected in support of the hydrologic and water quality components of the U.S. Geological Survey 's groundwater contamination investigation near...

Prompted by the need for a current, accurate, and repeatable delineation of irrigated acreage on the Snake River Plain, the U.S. Geological Survey entered into a cooperative agreement with the Idaho Department of Water Resources Image Analysis Facility and the U.S. Bureau of Reclamation to delineate 1980 land use form Landsat data. Irrigated acreage data were needed as input to...

As part of a study to obtain groundwater quality data in areas of Idaho were land- and water-resource development is expected to increase, water quality, geologic, and hydrologic data were collected for 74 wells in the Payette River basin, west-central Idaho, from July to October 1982. Historical (pre-1982) data from 13 wells were compiled with more recent (1982) data to define, on a
