The ground-water system and possible effects of underground coal mining in the Trail Mountain area, central Utah
Gregory C. Lines
1985, Water Supply Paper 2259
The ground-water system was studied in the Trail Mountain area in order to provide hydrologic information needed to assess the hydrologic effects of underground coal mining. Well testing and spring data indicate that water occurs in several aquifers. The coal-bearing Blackhawk-Star Point aquifer is regional in nature and is the...

Hydrologic effects of ground- and surface-water withdrawals in the Milford area, Elkhart and Kosciusko counties, Indiana
H.A. Lindgren, J. G. Peters, D.A. Cohen, E. J. Crompton
1985, Water-Resources Investigations Report 85-4166
Agricultural irrigation in northern Indiana has increased rapidly since 1975 and might double by the year 2000. A 16.5 square-mile area in north-central Indiana was studied to determine possible effects of increased irrigation on local water supply. In 1982, an average of 2 inches of water was used to irrigate...
Stratigraphy and characteristic mollusks of the Pamunkey Group (Lower Tertiary) and the Old Church Formation of the Chesapeake Group— Virginia coastal plain
