Ground-water resources of Limestone County, Texas
P.L. Rettman
1984, Open-File Report 84-713
Limestone County, located in east-central Texas, has small to plentiful ground-water supplies available, depending upon the location within the county. The Wilcox Group in the eastern part of the county has adequate supplies to meet the expected water demands in the foreseeable future. The thicker zones of the Wilcox Group...
Hydrology of area 53, northern Great Plains and Rocky Mountain coal provinces, Colorado, Wyoming, and Utah
N. E. Driver, J. M. Norris, Gerhard Kuhn
1984, Open-File Report 83-765
Hydrologic information and analysis are needed to aid in decisions to lease Federally owned coal and for the preparation of the necessary Environmental Assessments and Impact Study Reports. This need has become even more critical with the enactment of the Surface Mining Control and Reclamation Act of 1977 (Public Law...
Approximate water-level changes in wells in the Chicot and Evangeline aquifers, 1977-84 and 1983-84, and measured compaction, 1973-84, in the Houston-Galveston region, Texas
Jeffrey L. Strause
1984, Open-File Report 84-140
This report, which was prepared in cooperation with the City of Houston and Harris-Galveston Coastal Subsidence District, presents data on water-level changes during 1977-84 and 1983-84 in the Chicot and Evangeline aquifers (figs. 1-4) and data on measured compaction 1973-84 (fig. 5). Water levels in about 550 wells were used to...
Water-resources investigations of the U.S. Geological Survey in Wyoming, fiscal year 1984
S. L. Green (compiler)
1984, Open-File Report 84-622
This report contains lists and location maps of streamflow and reservoir stations, crest-stage partial-record stations, water-quality stations, sediment stations, and ground-water observation wells that are currently being operated. Water-resources appraisal projects in Wyoming are also described , including many that are related to development of energy resources. The general locations...
The principle of superposition and its application in ground-water hydraulics
T. E. Reilly, O.L. Franke, G.D. Bennett
1984, Open-File Report 84-459
The principle of superposition, a powerful methematical technique for analyzing certain types of complex problems in many areas of science and technology, has important application in ground-water hydraulics and modeling of ground-water systems. The principle of superposition states that solutions to individual problems can be added together to obtain solutions...
Chemical quality of the Saw Mill River, Westchester County, New York, 1981-83
R.J. Rogers
1984, Water-Resources Investigations Report 84-4225
Surface waters, bottom sediments and coatings formed on artificial substrates (ceramic tiles) were analyzed to evaluate the chemical quality of the Saw Mill River, New York. Heavy metals, nutrients, and organic contaminants were studied. Dissolved orthophosphate concentrations were highest in the lower third of the river. Dissolved manganese was the...
