Hydrogeologic unit map of the Piedmont and Blue Ridge provinces of North Carolina
Charles C. Daniel III, R.A. Payne
1990, Water-Resources Investigations Report 90-4035
The numerous geologic formations and rock types in the Piedmont and Blue Ridge provinces of North Carolina have been grouped into 21 hydrogeologic units on the basis of their water-bearing potential as determined from rock origin, composition, and texture. All major classes of rocks--metamorphic, igneous, and sedimentary--are present, although metamorphic...
Water resources data, Washington, water year 1989
M.B. Miles, W.D. Wiggins, G.P. Ruppert, R.L. Blaz, L.L. Reed, L.E. Hubbard
1990, Water Data Report WA-89-1
The Water Resources Division of the U.S. Geological Survey, in cooperation with State, local, and other Federal agencies, obtains a large amount of data pertaining to the water resources of Washington each water year. These data, accumulated during many water years, constitute a valuable data base for developing an improved...
Hydrogeologic, water-level, and water-quality data from monitoring wells at the U.S. Marine Corps Air Station, Cherry Point, North Carolina
L. C. Murray Jr., K. M. Keoughan
1990, Water-Resources Investigations Report 89-4200
Unlined hazardous-waste disposal sites at the U.S. Marine Corps Air Station, Cherry Point, North Carolina, are located near drinking-water supply wells that tap the Castle Hayne aquifer. Hydrogeologic and water-quality data were collected near 2 of these sites from 12 monitoring wells installed in May through June 1987. Near the northernmost...
Hydrogeology and preliminary assessment of the potential for contamination of the Memphis aquifer in the Memphis area, Tennessee
W. S. Parks
1990, Water-Resources Investigations Report 90-4092
Detailed maps of the thickness of the Jackson-upper Claibome confining unit and the altitude of the water table in the alluvium andfluvial deposits provide much new information concerning areas where downward leakage is or may be occurringfrom the water-table aquifers to theMemphrj aqutyer in the Memphis area. A detailed map of the altitude of the potentiometric surface...
Altitude of potentiometric surface, fall 1985, and historic water-level changes in the Fort Pillow aquifer in western Tennessee
W. S. Parks, J. K. Carmichael
1990, Water-Resources Investigations Report 89-4048
Recharge to the Fort Pillow aquifer of Tertiary age in Tennessee is from precipitation on the outcrop, which forms a narrow belt across western Tennessee, and by downward infiltration of water from the overlying fluvial deposits of Tertiary and Quaternary age and alluvium of Quaternary age or, where the upper...
Geology and ground-water resources of the Cockfield Formation in western Tennessee
W. S. Parks, J. K. Carmichael
1990, Water-Resources Investigations Report 88-4181
The Cockfield Formation of the Claiborne Group of Tertiary age underlies approximately 4,000 sq mi in western Tennessee. The formation consists primarily of lenticular beds of very fine to coarse sand, silt, clay, and lignite. The Cockfield Formation has been extensively eroded, and the original thickness is preserved only in...
Geohydrology and water quality of confined-drift aquifers in the Brooten-Belgrade area, west-central Minnesota
G. N. Delin
1990, Water-Resources Investigations Report 88-4124
Confined-drift aquifers in six aquifer zones identified in a 1,300-square-mile area of west-central Minnesota near Brooten and Belgrade range in thickness from 5 to 110 feet. Transmissivities generally range from 500 to 10,000 feet squared per day, and theoretical well yields generally range from 100 to 900 gallons per minute. Regional...
Quaternary geologic map of the Vicksburg 4° x 6° quadrangle, United States
W. A. Gilliland, K. V. Luza, D. E. Pope, E. G. Wermund, R. A. Miller, W. V. Bush, K. N. Jensen, W. D. Fishman, David S. Fullerton, David L. Weide, Charles A. Bush
Gerald Martin Richmond, editor(s)
1990, IMAP 1420(NI-15)
This map is part of the Quaternary Geologic Atlas of the United States (I-1420). It was first published as a printed edition in 1990. The geologic data have now been captured digitally and are presented here along with images of the printed map sheet and component parts as PDF files....
