Test drilling in basalts, Lalamilo area, South Kohala District, Hawaii
Warren E. Teasdale
1980, Open-File Report 80-1299
Test drilling has determined that a downhole-percussion airhammer can be used effectively to drill basalts in Hawaii. When used in conjunction with a foam-type drilling fluid, the hammer-bit penetration rate was rapid. Continuous drill cuttings from the materials penetrated were obtained throughout the borehole except from extremely fractured or weathered...
Hydraulic characteristics of an underdrained irrigation circle, Muskegon County wastewater disposal system, Michigan
M.G. McDonald
1980, Open-File Report 80-773
Muskegon County, Michigan, disposes of wastewater by spray irrigating farmland on its waste-disposal site. Buried drains in the highly permeable unconfined aquifer at the site control the level of the water table. Hydraulic conductivity of the aquifer and drain-leakance, the reciprocal of resistance to flow into the drains, was determined...
Oilspill analysis for the Cook Inlet and Shelikof Strait (proposed sale 60) Outer Continental Shelf lease area
Robert P. LaBelle, William B. Samuels, Kenneth J. Lanfear
1980, Open-File Report 80-863
An oilspill risk analysis was conducted to determine the relative environmental hazards of developing oil in different regions of the Cook Inlet and Shelikof Strait (Proposed Sale 60) Outer Continental Shelf (OCS) lease area. The probability of spill occurrences, likely movement of oil slicks, and locations of resources vulnerable to...
Supplemental data from the Ennis and other thermal-springs areas, Southwestern Montana, 1978-80
Robert B. Leonard, Wayne A. Wood
1980, Open-File Report 80-1182
Hydrogeologic data were collected principally during 1978-80 in eight hot-spring areas, in the Marysville geothermal test well, in the Butte Mine and in the Bitterroot and Missoula River valleys to provide a basis for evaluating the geothermal potential of the areas. Measurements are tabulated for subsurface temperatures, water levels, rates...
Potential for using the Upper Coachella Valley ground-water basin, California, for storage of artificially recharged water
Michael J. Mallory, Lindsay A. Swain, Stephen J. Tyley
1980, Open-File Report 80-599
This report presents a preliminary evaluation of the geohydrologic factors affecting storage of water by artificial recharge in the upper Coachella Valley, Calif. The ground-water basin of the upper Coachella Valley seems to be geologically suitable for large-scale artificial recharge. A minimum of 900 ,000 acre-feet of water could probably...
Microorganisms in stormwater; a summary of recent investigations
Gail E. Mallard
1980, Open-File Report 80-1198
All storm runoff contains a variety of bacteria, including total coliform, fecal coliform, and fecal streptococci, which are derived from the land over which the water flows. Most total coliform are native soil organisms, whereas the fecal coliform and fecal streptococci originate from the feces of wild and domestic animals....
Outer continental shelf oil and gas activities in the Pacific (Southern California) and their onshore impacts: a summary report, May 1980
George S. Macpherson, Janis Bernstein
1980, Open-File Report 80-645
Outer Continental Shelf (OCS) oil and gas exploration and development have been under way in the Pacific (Southern California) Region since 1966. During that time, there have been four Federal lease sales: in 1966, 1968, 1975 (Sale 35), and 1979 (Sale 48). Oil and gas production from three leases has...
