U.S. Geological survey program on toxic waste--ground-water contamination; proceedings of the Second technical meeting, Cape Cod, Massachusetts, October 21-25, 1985
S.E. Ragone
1988, Open-File Report 86-481
This study characterizes the clay minerals in sediments associated with a plume of creosote-contaminated groundwater. The plume of contaminated groundwater near Pensacola, FL, is in shallow, permeable, Miocene to Holocene quartz sand and flows southward toward Pensacola Bay. Clay-size fractions were separated from 41 cores, chiefly split-spoon samples at 13...
Ground-water data for Georgia, 1987
C. N. Joiner, M.S. Reynolds, W.L. Stayton, F.G. Boucher
1988, Open-File Report 88-323
This report was prepared in cooperation with the State of Georgia; Chatham County; Glynn County; the cities of Brunswick and Valdosta; and the Albany Water, Gas, and Light Commission. This report is the culmination of a concerted effort by dedicated personnel of the U.S. Geological Survey who...
U.S. Geological Survey ground-water studies in Iowa
R.C. Buchmiller
1988, Open-File Report 88-146
Ground water is the primary source for most water uses in Iowa. Ground-water resources supply 81 percent of the water withdrawn in Iowa for non-power-generating uses. Ground water from five principal aquifer systems is the source of drinking water for approximately 82 percent of the State's population. These aquifers range...
Brief descriptions of mines, prospects, and mineral occurrences in the Port Moller and Stepovak Bay quadrangles, Alaska peninsula
Frederic H. Wilson, Willis H. White, Gregory D. DuBois
1988, Open-File Report 88-666
This report contains brief descriptions of known mines, prospects, and mineral occurrences in the Port Moller and Stepovak Bay quadrangles on the Alaska Peninsula. These quadrangles, and the adjoining Simeonof Island quadrangle to the south were the subject of an Alaska Mineral Resource Assessment Program (AMRAP) mapping and mineral resource...
Summary of water data for the Janzen recharge investigation, Scott County, Kansas, 1980-86
L.E. Stullken
1988, Open-File Report 88-83
The U.S. Geological Survey, in cooperation with the Western Kansas Groundwater Management District No. 1, established data collection instrumentation around an earthen dam in Scott County , west-central Kansas. The dam was placed on an ephemeral drainage to monitor water storage behind the dam, precipitation, and groundwater levels in the...
Documentation of a steady-state saltwater-intrusion model for three-dimensional ground-water flow, and user's guide
D. B. Sapik
1988, Open-File Report 87-526
A finite-difference model that simulates three-dimensional flow of groundwater was modified to simulate steady flow of freshwater in a multiple-aquifer system containing freshwater and static saltwater. The two fluids are assumed to be immiscible, with constant but different densities, and are separated by a sharp interface. The interface position computed...
