Ground-water flow and quality near Canon City, Colorado
G. A. Hearne, D. W. Litke
1987, Water-Resources Investigations Report 87-4014
Water in aquifers that underlie the Lincoln Park area near Canon City, Colorado, contains measurable concentrations of chemical constituents that are similar to those in raffinate (liquid waste) produced by a nearby uranium ore processing mill. The objective of this study was to expand the existing geohydrologic data base by...
Simulation of trickle irrigation, an extension to the US Geological Survey's computer program VS2D
R. W. Healy
1987, Water-Resources Investigations Report 87-4086
A method is presented for simulating water movement through unsaturated porous media in response to a constant rate of application from a surface source. Because the rate at which water can be absorbed by soil is limited, the water will pond; therefore the actual surface area over which the water...
Evaluation of the potential for artificial ground-water recharge in eastern San Joaquin County, California — Phase 3
S. N. Hamlin
1987, Water-Resources Investigations Report 87-4164
Infiltration tests were used to evaluate the potential of basin spreading surface water as a means of artificially recharging the aquifer system in eastern San Joaquin County, California. Two infiltration sites near Lockeford and Linden were selected on the basis of information collected during the first two phases of the...
Changes in water quality of Michigan streams near urban areas, 1973-84
D. J. Holtschlag
1987, Water-Resources Investigations Report 87-4035
Monthly water-quality monitoring of streams was begun by Michigan Department of Natural Resources in 1973 to (1) determine temporal and spatial variability, (2) detect long-term trends, and (3) describe changes in water quality near urban areas. This report provides a statistical analysis and summary of data collected from 1973 through...
An evaluation of the bedrock aquifer system in northeastern Wisconsin
P.J. Emmons
1987, Water-Resources Investigations Report 85-4199
Ground water is a major source of water in northeastern Wisconsin. The lower Fox River valley, located between Lake Winnebago and Green Bay in northeastern Wisconsin, is the second largest population center in Wisconsin. By 1957, ground-water withdrawals had lowered the potentiometric surface of the aquifer system as much as...
Nonpoint-source agricultural chemicals in ground water in Nebraska; preliminary results for six areas of the High Plains Aquifer
Hsiu-Hsiung Chen, A.D. Druliner
1987, Water-Resources Investigations Report 86-4338
The reconnaissance phase of a study to determine the occurrence of agricultural chemicals from nonpoint sources in groundwater in six areas, which represented the major provinces of the High Plains aquifer in Nebraska is described. In 1984, water from 82 wells in the 6 study areas was analyzed for nitrate,...

Adequacy of NASQAN data to describe areal and temporal variability of water quality of the San Juan River drainage basin upstream from Shiprock, New Mexico
C. L. Goetz, Cynthia G. Abeyta
1987, Water-Resources Investigations Report 85-4043
Analyses indicate that water quality in the San Juan River drainage basin upstream from Shiprock, New Mexico, is quite variable from station to station. Analyses are based on water quality data from the U.S. Geological Survey WATSTORE files and the New Mexico Environmental Improvement Division 's files. In the northeastern...
A computer program for geochemical analysis of acid-rain and other low-ionic-strength, acidic waters
P.A. Johnsson, D. G. Lord
1987, Water-Resources Investigations Report 87-4095-A
ARCHEM, a computer program written in FORTRAN 77, is designed primarily for use in the routine geochemical interpretation of low-ionic-strength, acidic waters. On the basis of chemical analyses of the water, and either laboratory or field determinations of pH, temperature, and dissolved oxygen, the program calculates the equilibrium distribution of...

Trace-metal leaching from plumbing materials exposed to acidic ground water in three areas of the coastal plain of New Jersey
G. R. Kish, J. A. Macy, R.T. Mueller
1987, Water-Resources Investigations Report 87-4146
The U.S. Geological Survey analyzed trace metal concentrations in tap water from domestic wells in newly constructed homes in Berkeley Township, Ocean County and Galloway Township, Atlantic County, N. J. The potable water distribution systems in all of the homes sampled are constructed primarily of copper with lead-based solder points....
Statistical analysis relating well yield to construction practices and siting of wells in the Piedmont and Blue Ridge provinces of North Carolina
C.C. Daniel
1987, Water-Resources Investigations Report 86-4132
A statistical analysis was made of data from more than 6,200 water wells drilled in the fractured crystalline rocks of the Blue Ridge, Piedmont, and western edge of the Coastal Plain where crystalline rocks underlie sediments at shallow depths. The study area encompassed 65 countries in western North Carolina, an...
Ground-water resources of the Bisbee-Naco Area, Cochise County, Arizona
G. R. Littin
1987, Water-Resources Investigations Report 87-4103
The Bisbee-Naco Area is in southeastern Arizona and northeastern Sonora, Mexico. Annual rainfall averages about 17 inches. The basin fill is the principal aquifer and supplies about 95% of all water for domestic purposes. The total groundwater pumped in 1985 was about 6,500 acre/ft. Of that amount, 2,200 acre-ft was...
Movement of ground water in coal-bearing rocks near Fishtrap Lake in Pike County, Kentucky
R. W. Davis
1987, Water-Resources Investigations Report 87-4084
Eight test holes were core-drilled from various altitudes in a typical coal-bearing sequence rocks of Pennsylvania age in Pike County, eastern Kentucky. Vertical fractures were common in cores from shallow depths, but became less common or absent toward the bottom of two test holes drilled 400 and 291 ft deep....

A May 1987 potentiometric surface map of the Upper Floridan aquifer in west-central Florida depicts water levels for the annual low water-level period. Water levels in most wells measured in May 1987 were lower than in September 1986. May levels averaged about 0.5 foot higher than September levels in latitudes...
