Techniques used in mine-water problems of the east Tennessee zinc district
Deane Frederick Kent
1950, Circular 71
A study of ground water as related to mining in cavernous limestones and dolomites in eastern Tennessee was made in 1946 by the U. S. Geological Survey. Surface and subsurface mapping indicated the geologic control of underground channels. Several methods of tracing water were tried and new techniques in using...

A study of water quality degradation due to brine contamination was made in an area of about 1,700 sq mi in east-central Oklahoma. The study area coincides in part with the outcrop of the Vamoosa-Ada aquifer of Pennsylvanian age. Water samples collected from 180 wells completed in the Vamoosa-Ada aquifer...

During 1980, an estimated 121 million gallons of water per day was pumped in a 26-county area in east-central Georgia from sand aquifers of Paleocene and Late Cretaceous age. Maximum withdrawals were at the kaolin mining and processing centers in Twiggs, Wilkinson, and Washington Counties, where water levels have declined...
Geologic interpretations of seismic data, relocation of Route 116, Stations 7-135 in Cheshire, Mass.
Max E. Willard, Daniel Linehan
1950, Open-File Report 50-52
Three segments of the proposed relocation of Route 116, stations 7 to 135, in Cheshire, Mass. require shallow cuts. For the purpose of obtaining information on the depths to bedrock, and on the nature of the overlaying materials, seismic and geologic studies were made of the segments in October 1949....

Mineral constituents in water and their significance
T.B. Dover
1950, Open-File Report 50-69
Pure water does not exist in nature. Because water is a powerful solvent, every drop of rain water carries dissolved or suspended material - dust, pollen, and smoke, as well as the atmospheric gases, oxygen, nitrogen and carbon dioxide. When rain falls, the water running over the rocks and percolating...
