Preliminary plasma spectrometric analyses for selected elements in some geothermal waters from Cerro Prieto, Mexico
J.W. Ball, E. A. Jenne
1983, Water-Resources Investigations Report 83-4056
As part of a cooperative study with Dr. Alfred Truesdell, water samples collected from geothermal power production wells at Cerro Prieto, Mexico, were analyzed for selected elements by d.c. argon plasma emission spectroscopy. Spectral interferences due to the presence of high concentrations of Ca, Si, Na and K in these...

Ground-water exploration in the South Kohala district, Hawaii County, Hawaii, using vertical electrical sounding
James P. Kauahikaua, Dallas B. Jackson
1983, Open-File Report 83-67
Ten deep electrical resistivity soundings were completed across the island of Hawai?i near the town of Waimea in an effort to locate high-level, dike-impounded water. The resistivity data did not support the existence of a high-level water occurrence. Instead, the data show that a thick basal fresh-water lens underlies the...

1983, Open-File Report 82-861
Results of time-of-travel and dispersion studies are presented for the 77.0 mile reach of the Lehigh River from Francis E. Walter Lake to Easton, Pennsylvania. Rhodamine WT dye was injected at several points for a variety of several common flow conditions and its downstream travel was monitored at a number...

Hydrologic data from an area southwest of Tallahassee, Florida, where municipal wastewater effluent is applied by spray irrigation
M.C. Yurewicz
1983, Open-File Report 83-769
The effects of spray irrigation using municipal wastewater effluent on a ground-water system (in particular, on the water of the Floridan aquifer) were investigated. The area irrigated was 4 miles southwest of Tallahassee, Florida, on an area covered in part by pine forest and in part by selected grasses and...

1983, Open-File Report 83-21
The geology, water movement, and sediment characteristics in the upstream part of the Spring River basin have been appraised, to assist the U.S. EPA in their study of dioxin contamination in the area. The U.S. Environmental Protection Agency has confirmed that the dioxin compound, TCDD (2,3,7 ,8-tetrachlorodibenzo-p-dioxin), is present in...

Hydrogeologic and water-quality characteristics of the St. Peter aquifer, Southeast Minnesota
J. F. Ruhl, R. J. Wolf
1983, Water-Resources Investigations Report 83-4200
Quality of water in the St. Peter aquifer is generally acceptable for most uses. Sulfate concentrations increase toward the southwestern part of the aquifer because of highly mineralized leakage from overlying Cretaceous deposits. Concentrations of sodium, magnesium, and sulfate generally increase to the west, and those of calcium, bicarbonate, and...
