Preliminary evaluation of the Knox Group in Tennessee for receiving injected wastes
M. W. Bradley
1986, Water-Resources Investigations Report 85-4304
The EPA is authorized under the Safe Drinking Water Act to protect underground sources of drinking water from contamination. However, an aquifer may be exempted from protection and used for injected wastes where the aquifer meets criteria established in the EPA 's Underground Injection Control program. The Knox Group in...
Description of sediment data collected by the U.S. Geological Survey in small watersheds in coal-mining areas of the eastern United States, 1980-84
L. D. Arihood
1986, Open-File Report 86-309
Hydrologic data were collected by the U.S. Geological Survey from 20 small watersheds in the surface-mining areas of the eastern United States from 1980 through 1984 as part of the Survey1 s coal-hydrology program. Each data set includes sediment-concentration, streamflow, and precipitation data collected at 5- or 15-minute intervals. One...
Preliminary evaluation of the Highland Rim aquifer system in Tennessee for receiving injected wastes
M. W. Bradley
1986, Water-Resources Investigations Report 85-4252
The EPA has authority under the Safe Drinking Water Act to protect underground sources of drinking water from contamination by deep well injection. An aquifer, however, may be exempted from protection and used for injected wastes where the aquifer meets criteria established in the Agency 's Underground Injection Control program....
Water quality of Rhode Island streams
J. C. Briggs, J.S. Feiffer
1986, Water-Resources Investigations Report 84-4367
Water quality data collected from November 1979 through September 1983 at five stream stations within Rhode Island and one in Massachusetts show that concentrations of the common constituents were low. Mean water hardness at all sites was in the ' soft ' category. Sodium concentrations were less than 20 mg/L...
Potential effects of surface coal mining on the hydrology of the Little Bear Creek area, Moorhead coal field, southeastern Montana
N. E. McClymonds
1986, Water-Resources Investigations Report 85-4201
The Little Bear Creek area of the Moorhead Coal Field, 27 miles south of Ashland, Montana, 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 system and to assess potential effects of...
Results of experiments related to contact of mine-spoils water with coal, West Decker and Big Sky Mines, southeastern Montana
R. E. Davis, K. A. Dodge
1986, Water-Resources Investigations Report 86-4002
Batch-mixing experiments using spoils water and coal from the West Decker and Big Sky Mines were conducted to determine possible chemical changes in water moving from coal-mine spoils through a coal aquifer. The spoils water was combined with air-dried and oven-dried chunks of coal and air-dried and oven-dried crushed coal...
Geohydrology of the aquifers that may be affected by the surface mining of coal in the Fruitland Formation in the San Juan Basin, northwestern New Mexico
R. G. Myers, E.D. Villanueva
1986, Water-Resources Investigations Report 85-4251
A monitoring network of 50 wells was installed from 1975 to 1979 in the surface-mineable coal area. The purpose of the network was to collect hydrologic data and to establish a data base. The hydrologic data consist of water level measurements, water chemistry, and selected aquifer characteristics. The four aquifers...
Reconnaissance of the water resources and potential effects of mining of the Joliet-Fromberg coal tract, Carbon County, Montana
M. R. Cannon
1986, Water-Resources Investigations Report 86-4155
The Joliet-Fromberg coal tract in Carbon County, Montana, contains subbituminous to bituminous coal suitable for underground mining. A reconnaissance study of the area was conducted to identify water resources of the coal tract and to determine general effects that underground mining could have on the water resources. Surface-water resources consist...
Summary of hydrologic conditions in the Reedy Creek Improvement District, central Florida
Edward R. German
1986, Water-Resources Investigations Report 84-4250
The Reedy Creek Improvement is an area of about 43 square miles in southwestern Orange and northwestern Osceola Counties, Florida. A systematic program of hydrologic data collection in the Reedy Creek Improvement District and vicinity provided data for assessing the impact of development, mostly the Walt Disney World Theme Park...
