Geohydrology and susceptibility of major aquifers to surface contamination in Alabama; Area 8
J. C. Scott, R.H. Cobb, R.D. Castleberry
1987, Water-Resources Investigations Report 86-4360
The U.S. Geological Survey, in cooperation with the Alabama Department of Environmental Management, is conducting a series of geohydrologic studies to delineate the major aquifers and their susceptibility to contamination in Alabama. This report delineates and describes the geohydrology and susceptibility of the major aquifers to contamination in Area 8--Autauga,...
Preliminary water-use estimates in the United States in 1985
W.B. Solley, R.R. Pierce, C.F. Merk
1987, Open-File Report 87-692
Preliminary 1985 water use estimates are tabulated by State for the Und States, Puerto Rico, the Virgin Islands, and the District of Columbia. Preliminary estimates of water withdrawn from surface water and groundwater sources for offstream water use categories are presented prior to publication of the final estimates in a...
Geohydrology and susceptibility of Coldwater Spring and Jacksonville fault areas to surface contamination in Calhoun County, Alabama
J. C. Scott, W. F. Harris, R.H. Cobb
1987, Water-Resources Investigations Report 87-4031
Coldwater Spring in eastern Calhoun County, Alabama, is one of the largest springs in Alabama. The spring, which has an average discharge of about 31 million gallons per day, supplies water for about 70,000 people in the Anniston, Alabama area. A potentiometric map of the study area indicates that the...
Cost-effectiveness of the stream-gaging program in Missouri
L.A. Waite
1987, Water-Resources Investigations Report 87-4254
This report documents the results of an evaluation of the cost effectiveness of the 1986 stream-gaging program in Missouri. Alternative methods of developing streamflow information and cost-effective resource allocation were used to evaluate the Missouri program. Alternative methods were considered statewide, but the cost effective resource allocation study was restricted...
Cost effectiveness of the U.S. Geological Survey's stream-gaging program in Wisconsin
J.F. Walker, L.L. Osen, P.E. Hughes
1987, Water-Resources Investigations Report 86-4125
This report presents the results of a three-step evaluation of the stream-gaging program in Wisconsin. First, data uses and funding sources were identified for the 89 continuous-record gaging stations operated during the 1984 water year. Next, alternative methods of streamflow estimation were examined for three stations. A flow-routing model was...
Description of piezometer nests and water levels in the Rio Grande Valley near Albuquerque, Bernalillo County, New Mexico
S. K. Anderholm, T.F. Bullard
1987, Open-File Report 87-122
Twenty-four piezometers were installed from mid-October 1984 to mid-January 1985 in two sections of the Rio Grande valley near Albuquerque, New Mexico. Each cross section is comprised of four piezometer nests and each nest is comprised of three piezometers completed at different depths. The purpose of this report is to...
Effluent migration from septic tank systems in two different lithologies, Broward County, Florida
B.G. Waller, Barbara Howie, C. R. Causaras
1987, Water-Resources Investigations Report 87-4075
Two septic tank test sites, one in sand and one in limestone, in Broward County, Florida, were analyzed for effluent migration. Groundwater from shallow wells, both in background areas and hydraulically down-gradient of the septic tank system, was sampled during a 16-month period from April 1983 through August 1984. Water...
Trace organic compounds in wet atmospheric deposition: an overview
T.R. Steinheimer, S.M. Johnson
1987, Water-Resources Investigations Report 87-4033
An overview of the occurrence of organic compounds in wet atmospheric deposition is given. Multiplicity of sources and problems associated with source identification are discussed. Available literature is reviewed by using citations from Chemical Abstracts and Water Resources Abstracts through June 1985 and includes reports published through December 1984 that...
Water resources near Dillingham in the Bristol Bay Area, Alaska
R. L. Glass
1987, Water-Resources Investigations Report 87-4141
Dillingham, the largest community in the Bristol Bay area of Alaska, lies near the confluence of the Wood and Nushagak Rivers. Mean annual discharges for the Wood and Nushagak Rivers are 4,824 and 22,650 cu ft/sec. Flows generally are greatest in May through July and lowest in January through April....
Application of techniques to identify coal-mine and power-generation effects on surface-water quality, San Juan River basin, New Mexico and Colorado
C. L. Goetz, Cynthia G. Abeyta, E.V. Thomas
1987, Water-Resources Investigations Report 86-4076
Numerous analytical techniques were applied to determine water quality changes in the San Juan River basin upstream of Shiprock , New Mexico. Eight techniques were used to analyze hydrologic data such as: precipitation, water quality, and streamflow. The eight methods used are: (1) Piper diagram, (2) time-series plot, (3) frequency...
