Ground water in the Harrisburg-Halsey area, southern Willamette Valley, Oregon
F. J. Frank
1976, Water Supply Paper 2040
The Harrisburg-Halsey area lies between the Cascade and Coast Ranges in the southern Willamette Valley in northwestern Oregon. The area consists of approximately 350 square miles (910 km2) and includes a part of the lower foothills of the Coast and Cascade Ranges. Volcanic and marine sedimentary units exposed in the...
Sediment characteristics of streams in the eastern Piedmont and western Coastal Plain regions of North Carolina
Clyde E. Simmons
1976, Water Supply Paper 1798-O
The sediment-transport characteristics of streams were determined in a 15,500-square-kilometre (6,000-square-mile) area of the Coastal Plain and Piedmont regions of eastern North Carolina during 1969-73. The study covered all or parts of 21 counties and included data for 28 sediment-sampling stations in parts of 4 major river basins?the Roanoke, Pamlico,...
Artificial recharge through a well in fissured carbonate rock, west St. Paul, Minnesota
Harold O. Reeder, Warren W. Wood, G. G. Ehrlich, Ren Jen Sun
1976, Water Supply Paper 2004
The Prairie du Chien Group was injected with 2,754,000 gallons (368,200 cubic feet), or 10,430 cubic metres, of municipally treated water at about 100 gallons per minute (13.4 cubic feet per minute), or 6.3 litres per second, for 20 days. The injection-pipe system was designed to utilize pipe friction rather...
Digital-simulation and projection of water-level declines in basalt aquifers of the Odessa-Lind area, east-central Washington
J. E. Luzier, James A. Skrivan
1975, Water Supply Paper 2036
A digital computer program using finite-difference techniques simulates an intensively pumped, multilayered basalt-aquifer system near Odessa. The aquifers now developed are in the upper 1,000 feet of a regionally extensive series of southwesterly dipping basalt flows of the Columbia River Group. Most of the aquifers are confined. Those in the...
Geohydrologic reconnaissance of the upper Potomac River basin
Frank W. Trainer, Frank A. Watkins
1975, Water Supply Paper 2035
The upper Potomac River basin, in the central Appalachian region in Pennsylvania, Maryland, Virginia, and West Virginia, is a humid temperate region of diverse fractured rocks. Three geohydrologic terranes, which underlie large parts of the basin, are described in terms of their aquifer characteristics and of the magnitude and duration...
Selenium in waters in and adjacent to the Kendrick Project, Natrona County, Wyoming
Marvin A. Crist
1975, Water Supply Paper 2023
Selenium in concentrations exceeding the maximum limit, 0.01 milligrams per liter or 10 micrograms per liter, recommended by the U.S. Public Health Service in 'Drinking-Water Standards, 1962,' Public Health Pub. 956, is present in waters in areas near Casper, Wyo. Some streams containing selenium flow into the North Platte River...
