Ground water in the San Juan metropolitan area, Puerto Rico
H. R. Anderson
1976, Water-Resources Investigations Report 75-41
Ground water in the San Juan, Puerto Rico, area has played a declining role in water supply since the completion of the Lofza reservoir project in the early 1950's. Ground-water potential is limited because of the small size of the aquifers and susceptibility to seawater intrusion. Of the 30 million...

Chemical characteristics of the major thermal springs of Montana
Robert H. Mariner, T. S. Presser, William C. Evans
1976, Open-File Report 76-480
Twenty-one thermal springs in western Montana were sampled for chemical, isotope, and gas compositions. Most of the springs issue dilute to slightly saline sodium-bicarbonate waters of neutral to slightly alkaline pH. A few of the springs issue sodium-mixed anion waters of near neutral pH. Fluoride concentrations are high in most...

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,...

Studies of the geothermal aspect-of the Bridge area of the Raft River basin in south-central Idaho (fig. 1) by the U.S. Geological Survey began in 1972 when Young and Mitchell (1973) made a geochemical and geologic reconnaissance of selected thermal waters in Idaho. The Bridge area had been designated the...
Changes in the water supply in the Upper Republican Natural Resources District, Southwest Nebraska, from 1952-75
E.G. Lappala
1976, Open-File Report 76-498
Use of ground water for irrigation has increased rapidly in the Upper Republican Natural Resources District in southwestern Nebraska in recent years. The principal aquifer being developed is composed of saturated and gravel of the Ogallala Formation of Tertiary age. Water-level declines of as much as 16 feet (4.9 meters)...
Preliminary space image lineament maps of Alaska

1976, Open-File Report 76-341
Examination of images from Nimbus, NOAA and Landsat satellites has revealed a series of lineaments in the earth's surface in Alaska 1000 km or more in length (fig. 1). These lineaments occur as alinements of surface geologic structures, linear valleys or ridges, and linear changes in tonal contrast marking differences...
