Geohydrology of the valley-fill aquifer in the South Fallsburgh-Woodbourne area, Sullivan County, New York
H. R. Anderson, R. J. Dineen, W. G. Stelz, J. L. Belli
1982, Open-File Report 82-112
This report is the ninth in a series of map sets depicting geohydrologic conditions in selected aquifers in upstate New York. Geohydrologic data are compiled on six maps at 1:24,000 scale. Together the maps provide a comprehensive overview of a major valley-fill aquifer in southeastern Sullivan County. The maps include...
Geohydrology of the valley-fill aquifer in the Ramapo and Mahwah rivers area, Rockland County, New York
Richard Bridge Moore, D.H. Cadwell, W. G. Stelz, J. L. Belli
1982, Open-File Report 82-114
This report is the eighth in a series of 11 map sets depicting geohydrologic conditions in selected aquifers in upstate New York. Geohydrologic data are compiled on six maps at 1:24,000 scale. Together, the maps provide a comprehensive overview of a major valley-fill aquifer in southeastern Rockland County. The maps...
Geohydrology of the valley-fill aquifer in the Sprout and Fishkill creeks area, Dutchess County, New York
Richard B. Moore, R.G. LaFleur, W. G. Stelz, J. L. Belli
1982, Open-File Report 82-81
This report is the fifth in a series of 11 map sets depicting geohydrologic conditions in selected aquifers in upstate New York. Geohydrologic data are compiled on six maps at 1:24,000 scale. Together the maps provide a comprehensive overview of a major valley-fill aquifer in southwestern Dutchess County and a...
Ground-water levels and water quality in an area near Topaz Lake, Douglas County, Nevada
Jon O. Nowlin
1982, Open-File Report 80-2046
Intensive residential development of land along the northwest shore of Topaz Lake has raised concern regarding the adequacy of the water supply and possible effects of septic-tank effluents on the quality of local ground water and the lake. Existing data on water levels, well construction, and water quality were compiled,...
Determination of ultimate carbonaceous BOD and the specific rate constant (K1)
J. K. Stamer, J. P. Bennett, Stuart W. McKenzie
1982, Open-File Report 82-645
Ultimate carbonaceous biochemical oxygen demand (BODu) and the specific rate constant (K1) at which the demand is exerted are important parameters in designing biological wastewater treatment plants and in assessing the impact of wastewater on receiving streams. An analytical method is presented which uses time-series concentrations of BOD, defined as...
Multielement chemical and statistical analyses from a uranium hydrogeochemical and stream-sediment survey in and near the Elkhorn Mountains, Jefferson County, Montana: Part II, Stream sediments
V. J. Suits, K. J. Wenrich
1982, Open-File Report 82-203-B
Fifty-two stream-sediment samples, collected from an area south of Helena, Jefferson County, Montana, were sieved into two size fractions (<88 ?m, and between 88 and 149 ?m) and analyzed for 80 different chemical species. Of these species, 43 showed detectable variation over the area, 31 were subjected to correlation analysis...
Multielement chemical and statistical analyses from a uranium hydrogeochemical and stream-sediment survey in and near the Elkhorn Mountains, Jefferson County, Montana. Part I: Surface water
V. J. Suits, K. J. Wenrich
1982, Open-File Report 82-203-A
Fifty-two surface-water samples, collected from an area south of Helena, Jefferson County, were analyzed for 51 chemical species. Of these variables, 35 showed detectable variation over the area, and 29 were utilized in a correlation analysis. Two populations are distinguished in the collected samples and are especially evident in the...
Annual snowmelt and rainfall peak-flow data on selected foothills region streams, South Platte River, Arkansas River, and Colorado River basins, Colorado
J. G. Elliott, R.D. Jarrett, J.L. Ebling
1982, Open-File Report 82-426
Peak flows in the foothills region of Colorado are attributable to two meteorological sources--snowmelt and rainfall. As part of a study of the hydrology of foothills streams in Colorado, charts from streamflow gages on unregulated streams were examined to determined the source of peak-flow events. Snowmelt-runoff peaks were distinguished from...
