Availability of ground water from the alluvial aquifer on the Nisqually Indian Reservation, Washington
W. E. Lum II
1984, Water-Resources Investigations Report 83-4185
A digital model using finite-difference techniques was constructed to simulate ground-water flow in an alluvial aquifer on the Nisqually Indian Reservation. The maximum long-term rate of pumping from individual wells, based on available data, is about 0.75 cubic feet per second (340 gallons per minute). Data on the extent, hydraulic...
Ice volumes on Cascade volcanoes: Mount Rainier, Mount Hood, Three Sisters, and Mount Shasta
C. L. Driedger, P.M. Kennard
1984, Open-File Report 84-581
During the eruptions of Mount St. Helens the occurrence of floods and mudflows made apparent the need for predictive water-hazard analysis of other Cascade volcanoes. A basic requirement for such analysis is information about the volumes and distributions of snow and ice on other volcanoes.A radar unit contained in a...
Ground-water monitoring at Santa Barbara, California: Phase 2 — Effects of pumping on water levels and on water quality in the Santa Barbara ground-water basin
Peter Martin
1984, Water Supply Paper 2197
From July 1978 to January 1980, water levels in the southern part of the Santa Barbara ground-water basin declined more than 100 feet. These water-level declines resulted from increases in municipal pumping since July 1978. The increase in municipal pumping was part of a basin-testing program designed to determine the...
Geological Survey research, fiscal year 1981
Water Resources Division, U.S. Geological Survey
1984, Professional Paper 1375
A summary of recent significant scientific and economic results accompanied by a list of geologic, hydrologic, and cartographic investigations in progress....
The Georges Bank monitoring program, 1984: Analysis of trace metals in bottom sediments during the second year of monitoring
Michael H. Bothner, R.R. Rendigs, Esma Campbell, M. W. Doughten, C.M. Parmenter, M. J. Pickering, R. G. Johnson, J.R. Gillison
1984, Circular 936
Of the 12 elements analyzed in bulk (undifferentiated) sediments collected adjacent to drilling rigs on Georges Bank, only barium was found to increase in concentration during the drilling period (July 1981 until September 1982). The maximum postdrilling concentration of barium (a major element in drilling mud) reached 172 ppm in...
Sewage plume in a sand and gravel aquifer, Cape Cod, Massachusetts
Denis R. LeBlanc
1984, Water Supply Paper 2218
Secondarily treated domestic sewage has been disposed of on surface sand beds at the sewage treatment facility at Otis Air Force Base, Massachusetts, since 1936. Infiltration of the sewage through the sand beds into the underlying unconfined sand and gravel aquifer has resulted in a plume of sewage-contaminated ground water...
A filtration and column-adsorption system for onsite concentration and fractionation of organic substances from large volumes of water
J.A. Leenheer, T.I. Noyes
1984, Water Supply Paper 2230
A portable filtration and column-adsorption system which can concentrate suspended sediment and dissolved-aqueous organic substances onsite was developed. Organic solutes also are fractionated into hydrophobic- and hydrophilic-acid, base, and neutral fractions. Subsequent isolation of organic solutes from fraction concentrates and extraction of organic constituents in suspended sediment entrained on filter...
