Hydrogeologic data for selected test wells drilled in the Fort Union coal region, eastern Montana

Hydrologic and geologic data have been collected as part of energy-related projects conducted by the U.S. Geological Survey in 11 counties of eastern Montana. Records of 408 test wells are tabulated in this report. The data include well location, type of well, date drilled, well depth, type and diameter of casing, depth cased, interval open to well, principal aquifer, depth to water level, water-level-record dates, water-quality-sampling record, and type of logs available. Location of the wells is shown by county on maps at a scale of 1:500,000.

Selected hydrogeologic data from southern Sweet Grass County, south-central Montana

Selected hydrogeologic data from Sweet Grass County south of the Yellowstone River have been compiled to show baseline ground-water conditions. Included are records from a 1981 onsite inventory of 94 water wells and 30 springs. Chemical analyses of water show the major cation and anion concentrations for 40 wells and 14 springs. Concentrations of 17 trace elements in water from 12 of the wells and 9 of the springs were determined by an argon coupled emission spectrometer. (USGS)

Hydrologic data from selected wells in the Helena Valley, Lewis and Clark County, Montana

Hydrologic data were collected during 1978-79 to aid in evaluating the hydrologic conditions in shallow aquifers beneath the Helena Valley, Montana. The locations of 52 shallow test wells augered during the study are shown on a map at a scale of 1:48,000. Periodic water-level measurements and water-quality analyses for the test holes are listed in tables. Water temperature, specific conductance, and nitrate concentration are given for water samples collected from 98 domestic wells, and chemical analyses are included for 11 domestic and irrigation wells. In addition, water-level drawdown and recovery data are plotted on graphs for five pumped wells and three observation wells. (Kosco-USGS)
