WATEQF; a FORTRAN IV version of WATEQ : a computer program for calculating chemical equilibrium of natural waters
Niel Plummer, Blair F. Jones, Alfred Hemingway Truesdell
1976, Water-Resources Investigations Report 76-13
WATEQF is a FORTRAN IV computer program that models the thermodynamic speciation of inorganic ions and complex species in solution for a given water analysis. The original version (WATEQ) was written in 1973 by A. H. Truesdell and B. F. Jones in Programming Language/one (PL/1.) With but a few exceptions,...
Map showing configuration and thickness, and potentiometric surface and water quality in the Madison Group, Powder River basin, Wyoming and Montana
F. A. Swenson, W. R. Miller, W.G. Hodson, F. N. Visher
1976, IMAP 847-C
With development of the coal resources of the Powder River Basin of Wyoming and Montana the demand for water will increase greatly. The study upon which this report is based was designed to make a preliminary evaluation of the available geo-hydrologic data for the Madison Group, which is an extensive...

Summary appraisals of the nation's ground-water resources – Great Basin region
Thomas E. Eakin, Don Price, J. R. Harrill
1976, Professional Paper 813-G
Ground-water withdrawals by wells in the Great Basin Region were about 1.1 million acre-feet (1,360 cubic hectometres) in 1970. Most of these withdrawals were from 87 of the 234 hydrographic areas in the region. Withdrawals ranged from about 1,000 acre-feet (1.2 cubic hectometres) to more than 100,000 acre-feet (123 cubic...

Computer-enhanced LANDSAT imagery as a tool for mineral exploration in Alaska
Nairn Albert, Pat S. Chavez
1976, Open-File Report 76-65
Recent work in the Nabesna and McCarthy quadrangles, Alaska, indicates that computer-enhanced LANDSAT imagery shows many of the known mineral deposits and can help in the prediction of potential mineral occurrences. False color, "simulated natural color" and color ratio techniques, were used successfully in conjunction with a black and white,...

Water resources of the Myakka River basin area, southwest Florida
Boyd F. Joyner, Horace Sutcliffe Jr.
1976, Water-Resources Investigations Report 76-58
Ground water in the Myakka River basin area of southwest Floria is obtained from a water-table aquifer and from five zones in an artesian aquifer. Wells in the water-table aquifer yield generally less than 50 gpm and dissolved solids concentration is less than 500 mg/liter except in coastal areas and...
Hydrologic relations between lakes and aquifers in a recharge area near Orlando, Florida
William F. Lichtler, G.H. Hughes, F. L. Pfischner
1976, Water-Resources Investigations Report 76-65
The three lakes investigated in Orange County, Florida, gain water from adjoining water-table aquifer and lose water to Floridan aquifer by downward leakage. Net seepage (net exchange of water between lake and aquifers) can be estimated by equation S = AX + BY, where S is net seepage, X represents...
Backflushing Filters for Field Processing of Water Samples Prior to Trace-Element Analyses
V. C. Kennedy, E. A. Jenne, J.M. Burchard
1976, Water-Resources Investigations Report 76-126
A portable unit is described for filtering water samples at field sites in such a manner that the filtrate is suitable for analysis not only of major constituents but also of trace elments at the mocrogram-per-liter level. A battery-operated peristaltic pump forces the water sample through medical-grade silicone tubing into...
