Estimation of vertical hydraulic conductivity of the clay layer between the Eutaw and Gordo aquifers in the vicinity of Faunsdale, Marengo County, Alabama
Michael Planert, A.K. Sparkes
1985, Water-Resources Investigations Report 85-4083
The vertical hydraulic conductivity of the confining bed between the Eutaw and Gordo aquifers in the vicinity of Faunsdale, in northeast Marengo County, Alabama, is 1x10(-5) foot per day or less. Modeling vertical conductivities larger than 1x50(-5) foot per day produced drawdowns in the Eutaw aquifer greater than those observed...
Reconnaissance of selected organic contaminants in effluent and ground water at fifteen municipal wastewater treatment plants in Florida, 1983- 84
J. B. Pruitt, D.E. Troutman, G. A. Irwin
1985, Water-Resources Investigations Report 85-4167
Results of a 1983-84 reconnaissance of 15 municipal wastewater treatment plants in Florida indicated that effluent from most of the plants contains trace concentrations of volatile organic compounds. Chloroform was detected in the effluent at 11 of the 15 plants and its common occurrence was likely the result of chlorination....
The difference between the potentiometric surfaces of the Magothy aquifer of September 1982 and September 1984 in southern Maryland
Frederick K. Mack, Judith C. Wheeler, Stephen E. Curtin, David C. Andreasen
1985, Water-Resources Investigations Report 85-4337
The potentiometric map is highlighted with indications concerning: (1) outcrop areas of the Magothy aquifer; (2) the potentiometric contour of the aquifer; (3) observation and/or supply wells yielding < 10,000 gallons/day (gpd); and (4) other supply wells with yields > 10,000 gpd. ...
Preliminary map showing the potentiometric surface of the Aquia aquifer in southern Maryland, September 1984
Frederick K. Mack, Judith C. Wheeler, Stephen E. Curtin, David C. Andreasen
1985, Water-Resources Investigations Report 85-4338
The potentiometric map is highlighted with indications concerning: (1) outcrop areas of the Aquia aquifer; (2) the potentiometric contour of the aquifer; (3) observation and/or supply wells yielding < 10,000 gallons/day (gpd); and (4) other supply wells with yields > 10,000 gpd. (Lantz-PTT)...
Potentiometric surface and water quality in the Principal Aquifer, Mississippian Plateaus region, Kentucky
R. O. Plebuch, R.J. Faust, M.A. Townsend
1985, Water-Resources Investigations Report 84-4102
The Mississippian Plateaus region is the outcrop area of rocks of Mississippian age which extends as a broad arcuate band around the Western Coal Field in westcentral Kentucky. Much of the area is characterized by plains of low relief containing numerous sinkholes, subsurface drainage, and a low density of surface...
The geohydrologic system and probable effects of mining in the Sand Creek-Hanks lignite area, western Williams County, North Dakota
C. A. Armstrong
1985, Water-Resources Investigations Report 85-4089
The investigation was undertaken to define the geohydrology of the Sand Creek-Hanks area and to project probable hydrologic effects of lignite mining on the area. Aquifers occur in sandstone beds in the Fox Hills Sandstone and the Hell Creek Formation of Cretaceous age and in sandstone lenses and lignite beds...
Potential effects of surface coal mining on the hydrology of the Horse Creek area, Sheridan and Moorhead coal fields, southeastern Montana
N. E. McClymonds
1985, Water-Resources Investigations Report 84-4239
The Horse Creek area of the Sheridan and Moorhead coal fields, 16 miles east of the Decker Coal Mines near the Tongue River, contains large reserves of Federally owned coal that have been identified for potential lease sale. A hydrologic study was conducted in the area to describe existing hydrologic...
