Geohydrologic descriptions of selected solid waste disposal sites in Puerto Rico
Arturo Torres-Gonzalez, Fernando Gómez-Gómez
1982, Open-File Report 81-490
Fifty solid-waste disposal sites in Puerto Rico were examined in 1977 and ranked according to their potential for degradation of the water resources. Twenty-five of the sites show significant leachate pollution potential. The cover material at 21 sites is relatively permeable and offers insignificant attenuation to leachates. Thirty-six sites are...

Chloride and total hardness concentrations of water from the upper part of the Floridan Aquifer in St. Johns County, Florida
Paul S. Hampson, Eugene C. Hayes
1982, Open-File Report 81-907
Data collected from 1976 to 1979 indicate large water-quality variations in the upper 300 feet of the Floridan aquifer in St. Johns County, Florida. Chloride concentrations range from less than 10 milligrams per liter in the northwestern part of the county to more than 1,000 milligrams per liter in the...
Determination of the true density of pulverized coal samples
R.W. Stanton
1982, Open-File Report 82-835
A method using the gas-comparison pycnometer with helium gas as the penetrating medium measures precisely the true volume of a pulverized coal sample. The true density of a solid is calculated as the true unit volume of the solid exclusive of its pore space which is divided into the weight...
Preliminary projections of the effects of chloride-control structures on the Quaternary aquifer at Great Salt Plains, Oklahoma
J.E. Reed
1982, Water-Resources Investigations Report 80-120
About 1,200 tons of chloride per day are added to the salt load of the Salt Fork Arkansas River at Great Salt Plains Lake.from brine discharge from the rocks of Permian age in the vicinity of the lake. The U.S. Army Corps of Engineers has planned a chloride-control project. The...

Simulated changes in water levels in the Minjur Aquifer, Riyadh area, Saudi Arabia
J. F. Williams, I.A. Sagaby
1982, Open-File Report 82-371
A two-dimensional finite-difference computer model of the Minjur aquifer in the Riyadh area of Saudi Arabia was developed to simulate and predict drawdown in an aquifer which, in 1979, supplied more than 80 percent of all water used in this capital area. The Minjur was modeled as a confined aquifer...
