Hydrogeochemistry and simulated solute transport, Piceance Basin, northwestern Colorado
S. G. Robson, G.J. Saulnier Jr.
1981, Professional Paper 1196
Oil-shale mining activities in Piceance basin in northwestern Colorado could adversely affect the ground- and surface-water quality in the basin. This study of the hydrology and geochemistry of the area used ground-water solute-transport-modeling techniques to investigate the possible impact of the mines on water quality. Maps of the extent and...

This report provides a record of the flood of September 16, 1975, and associated hydrologic data. These data can be used in making rational decisions in formulating effective flood-plain regulations that would minimize flood problems in the Tallaboa Valley.The Tallaboa Valley (fig. 1) lies on the southwestern coast of Puerto...
Appearance and distribution of the gas hydrate reflection in the Blake Ridge region, offshore southeastern United States
Charles K. Paull, William P. Dillon
1981, Miscellaneous Field Studies Map 1252
A strong reflection parallel to the sea floor has been observed in seismic-reflection profiles in the Blake Ridge area off the southeastern United States. This reflection occurs at a subbottom depth of 400 to 700 m, in water depths of 750 to 3750 m. Because the reflection parallels the sea...

Survey of selected organic compounds in aquifers of New York State excluding Long Island
Roy A. Schroeder, Deborah S. Snavely
1981, Water-Resources Investigations Report 81-47
Samples from 56 wells at 49 sites in New York State, excluding Long Island, were analyzed by gas chromatography/mass spectrometry for the presence of organic compounds designated ' priority pollutants ' by the U.S. Environmental Protection Agency. Most samples were taken from public-supply wells tapping shallow, permeable aquifers, the most...
Water use in Ohio, 1975
R. Michael Hathaway, Michael Eberle
1981, Water-Resources Investigations Report 81-17
The estimated water use in Ohio for all purposes in 1975 was 16 ,431 million gallons per day. Of this total, 15,321 were taken from surface water while the remaining 1,110 represent ground-water withdrawals. Totals by category are as follows (in million gallons per day): Thermoelectric power generation, 12 ,404;...
Multi-saline sample distillation apparatus for hydrogen isotope analyses: Design and accuracy
Afifa Afifi Hassan
1981, Water-Resources Investigations Report 81-25
A distillation apparatus for saline water samples was designed and tested. Six samples may be distilled simultaneously. The temperature was maintained at 400 C to ensure complete dehydration of the precipitating salts. Consequently, the error in the measured ratio of stable hydrogen isotopes resulting from incomplete dehydration of hydrated salts...
