Hydrogeologic characteristics of the Lee Acres Landfill Area, San Juan County, New Mexico
K. D. Peter, R. A. Williams, K. W. King
1987, Water-Resources Investigations Report 87-4246
Identification of the presence of volatile organic compounds in liquid-waste lagoons in New Mexico at the Lee Acres landfill, beneath a refinery south of the landfill, and in nearby residential wells has led to an hydrologic investigation of the area. The alluvium underlying an arroyo adjacent to the landfill mostly...
Estimates of consumptive use and ground-water return flow using water budgets in Palo Verde Valley, California
Sandra J. Owen-Joyce, Steven L. Kimsey
1987, Water-Resources Investigations Report 87-4070
Palo Verde Valley, California, is an agricultural area in the flood plain of the Colorado River where irrigation water is diverted from the river and groundwater is discharged to a network of drainage ditches and (or) the river. Consumptive use by vegetation and groundwater return flow were calculated using water...
Geohydrology of the Antelope Valley Area, California and design for a ground-water-quality monitoring network
L.F. Duell
1987, Water-Resources Investigations Report 84-4081
A basinwide ideal network and an actual network were designed to identify ambient groundwater quality, trends in groundwater quality, and degree of threat from potential pollution sources in Antelope Valley, California. In general, throughout the valley groundwater quality has remained unchanged, and no specific trends are apparent. The main source...
Physical properties of the surface materials at the Viking landing sites on Mars
H. J. Moore, R.E. Hutton, G.D. Clow, C.R. Spitzer
1987, Professional Paper 1389
This report summarizes the results of the Physical Properties Investigation of the Viking '75 Project, activities of the surface samplers, and relevant results from other investigations. The two Viking Landers operated for nearly four martian years after landing on July 20 (Lander 1) and Sept. 3 (Lander 2), 1976; Lander...
Activities of the Alaska District, Water Resources Division, U.S. Geological Survey, 1987
E. F. Snyder (compiler)
1987, Open-File Report 87-38
Hydrologic data collection activities by the U.S. Geological Survey in Alaska are described. Seventeen projects were active in 1987. Each description includes information on period of project, project chief, funding sources, location, purpose, current status, and published or planned reports. The compilation also contains a bibliography of reports published by...
Analytical results and sample locality map of stream-sediment, heavy mineral-concentrate, rock, and water samples from the Skedaddle (CA-020- 612) and Dry Valley Rim (CA-020-615) Wilderness Study Areas, Lassen County, California, and Washoe County, Nevada
B. M. Adrian, J. G. Frisken, L. A. Bradley, Cliff D. Taylor, J. B. McHugh
1987, Open-File Report 87-494
In the summer of 1985, the U.S. Geological Survey conducted a reconnaissance geochemical survey of the Skedaddle (CA-020-612) and Dry Valley Rim (CA-020-615) Wilderness Study Areas in Lassen County, California, and Washoe County, Nevada.Skedaddle and Dry Valley Rim are contiguous wilderness study areas (WSA) located in the eastern part of...
Effect of reduced industrial pumpage on the migration of dissolved nitrogen in an outwash aquifer at Olean, Cattaraugus County, New York
M. P. Bergeron
1987, Water-Resources Investigations Report 85-4082
A quasi-three-dimensional digital groundwater flow model of a shallow outwash aquifer system at Olean, New York, was developed to study the effects of several pumping alternatives on groundwater flow and stream seepage. Nitrogen compounds have contaminated the aquifer in an industrial park in North Olean. Pumping from seven industrial production...
