Ground-water monitoring at Santa Barbara, California; Phase 2-effects of pumping on water levels and water quality in the Santa Barbara ground-water basins
Peter Martin
1982, Open-File Report 82-366
From July 1978 to January 1980, water levels declined more than 100 feet in the southern part of the Santa Barbara ground-water basin. The water-level declines are the result of increases in municipal pumping since July 1978. The increase in municipal pumping was part of a basin-testing program to determine...
Hydrologic data for the Potomac Formation in New Castle County, Delaware
Mary M. Martin, Judith M. Denver
1982, Open-File Report 81-916
Hydrologic data for the Potomac Formation in New Castle County, Delaware, consist of records of historical ground-water pumpage, water levels, water quality, and surface-water discharge. This report includes records of 405 wells and hydro-graphs of water levels in 86 wells. Pumpage from 20 well fields is reported. Also included are...
Ground water and geology of Marquette County, Michigan
C. J. Doonan, J. L. Van Alstine
1982, Open-File Report 82-501
Ground-water resources of Marquette County are about evenly divided between bedrock aquifers and aquifers in glacial deposits. In the northern and the extreme southern parts of the county, most wells are completed in bedrock at depths less than 100 feet. In the central part, most wells are completed in glacial...
Water resources of the Gig Harbor Peninsula and adjacent areas, Washington
B. W. Drost
1982, Open-File Report 81-1021
The study area is a remnant of a glacial-drift plain nearly surrounded by marine embayments. A water-resources appraisal was made because the area is experiencing rapid population growth. Additional ground water is available for use in the study area. At least 11 cubic feet per second, five times the 1978...
Reconnaissance geochemical survey of the At Taif-Al Bahah region, southern Hijaz, Kingdom of Saudi Arabia
E. A. Du Bray, J. L. Doebrich
1982, Open-File Report 82-790
Pan concentrates were prepared from 265 wadi sediment samples collected during a geochemical reconnaissance conducted between At Taif and Al Bahah to further assess previously identified tungsten anomalies and to locate additional mineralized rock. The samples were analyzed by semiquantitative spectrographic methods for 30 elements, and tungsten was determined by...
Report of the annual yield of the Arkansas River basin for the Arkansas River Basin Compact, Arkansas-Oklahoma, 1981 water year
G.L. Ducret Jr.
1982, Open-File Report 82-168
The computed annual yield and deficiency of the subbasins as defined in the Arkansas River Compact, Arkansas-Oklahoma, 1980, are presented. Actual runoff from the subbasins and depletion caused by major reservoirs in the compact area are also given. Monthly, maximum, minimum, and mean discharges are shown for the 14 streamflow...
Procedures for assessment of cumulative impacts of coal mining on the hydrologic balance
Alan M. Lumb
1982, Open-File Report 82-334
Techniques were developed to assess the probable cumulative impacts of anticipated surface mining upon the hydrology of and area. An activity profile of cumulative drainage area versus river miles downstream from the surface mining site is constructed that shows major water uses, flood prone areas, and stream classifications. From the...
