An evaluation of the bedrock aquifer system in northeastern Wisconsin
P.J. Emmons
1987, Water-Resources Investigations Report 85-4199
Ground water is a major source of water in northeastern Wisconsin. The lower Fox River valley, located between Lake Winnebago and Green Bay in northeastern Wisconsin, is the second largest population center in Wisconsin. By 1957, ground-water withdrawals had lowered the potentiometric surface of the aquifer system as much as...
Streamflow characteristics at hydrologic bench-mark stations
C.L. Lawrence
1987, Circular 941
The Hydrologic Bench-Mark Network was established in the 1960's. Its objectives were to document the hydrologic characteristics of representative undeveloped watersheds nationwide and to provide a comparative base for studying the effects of man on the hydrologic environment. The network, which consists of 57 streamflow gaging stations and one lake-stage...
Reconnaissance of hydrology, land use, ground-water chemistry, and effects of land use on ground-water chemistry in the Albuquerque-Belen basin, New Mexico
S. K. Anderholm
1987, Water-Resources Investigations Report 86-4174
In 1984, the U.S. Geological Survey began regional assessments of groundwater contamination in 14 areas, one of which was the Albuquerque-Belen basin. Groundwater recharge occurs along the basin margins. Groundwater discharge occurs as evapotranspiration in the Rio Grande valley, pumpage, and groundwater flow to the Socorro basin. Open-space land use,...
Description and testing of three moisture sensors for measuring surface wetness on carbonate building stones
R.B. See, M.M. Reddy, R. G. Martin
1987, Water-Resources Investigations Report 87-4177
Three sensors were tested on building stones exposed to conditions that produce deposition of moisture. A relative humidity probe, a gypsum collected circuit grid, and a limestone block resistor were tested as sensors for determining surface wetness. Sensors were tested under laboratory conditions of constant relative humidity and temperature and...
Uranium resource assessment by the Geological Survey; methodology and plan to update the national resource base
Warren Irvin Finch, Richard B. McCammon
1987, Circular 994
Based on the Memorandum of Understanding {MOU) of September 20, 1984, between the U.S. Geological Survey of the U.S. Department of Interior and the Energy Information Administration {EIA) of the U.S. Department of Energy {DOE), the U.S. Geological Survey began to make estimates of the undiscovered uranium endowment of selected...
Distribution and movement of trichloroethylene in ground water in the Tucson area, Arizona
S. A. Leake, R. T. Hanson
1987, Water-Resources Investigations Report 86-4313
In 1981, investigations of groundwater quality around Tucson International Airport revealed a number of wells that pumped water contaminated with trichloroethylene. Subsequent investigations resulted in the delineation of three distinct areas of contamination, the largest of which encompasses about 5 sq mi of aquifer surface area. Most of the contamination...
Flood of April 1987 in Maine, Massachusetts, and New Hampshire
R. A. Fontaine
1987, Open-File Report 87-460
Widespread flooding ocurred through a large part of New England in early to mid-April 1987. The States affected most by these floods were Maine, Massachusetts, and New Hampshire. The flooding was the result of two distinct storms-one that brought heavy rains to the area from March 30 to April 2...
