Development of sinkholes resulting from man's activities in the Eastern United States
John G. Newton
1987, Circular 968
Development of induced sinkholes in carbonate terranes in the Eastern United States has resulted in costly damage and water pollution. Previously, detailed investigations of sinkholes were limited to Alabama and Missouri, with the most comprehensive being in Alabama. An investigation of the remainder of the area was made in 1981...
Patterns of acid deposition variability in the Eastern United States, 1981-84
H.F. Lins, K.J. Lanfear, T. L. Schertz
1987, Open-File Report 87-454
An increase in pH and a decrease in sulfate concentration of precipitation were recorded at National Atmospheric Deposition Program and National Trends Network (NADP/NTN) monitoring sites in the Eastern United States between 1981 and 1984. The decline in acidity, however, was not spatially or temporally uniform. The range in acidity...

Quality of ground water in Idaho
Johnson J. Yee, William R. Souza
1987, Water Supply Paper 2272
The major aquifers in Idaho are categorized under two rock types, sedimentary and volcanic, and are grouped into six hydrologic basins.

1987, Water-Resources Investigations Report 86-4321
Ground-water flow in the confined- and unconfined-drift aquifers near Appleton and Benson, Minnesota, was simulated with a three-dimensional finite-difference ground-water-flow model. Model results indicate that 98 percent of the total inflow to the modeled area is from precipitation. Of the total outflow, 38 percent is ground-water discharge to the Pom...

W. W. Staubitz, Todd S. Miller
1987, Water-Resources Investigations Report 86-4317
The Onondaga aquifer is a nearly flat-lying, 25- to 110-foot-thick, cherty limestone with moderately developed karst features such as sinkholes, disappearing streams, and solution-widened joints. Most groundwater moves through solution-widened bedding planes, although some moves through vertical joints. The yield of water from 42 wells ranges from 3 to 100...
