1991, Open-File Report 91-75
Beginning in 1986, the U.S. Congress appropriated funds for the U.S. Geological Survey to test and refine concepts for a National Water-Quality Assessment (NAWQA) Program. The long-term goals of the full-scale program are to: (1) provide a nationally consistent description of current water-quality conditions for a large part of the...
Ground-water levels, flow, and quality in northwestern Elkhart County, Indiana, 1980-89
R.F. Duwelius, C.A. Silcox
1991, Water-Resources Investigations Report 91-4053
Ground-water data were collected in northwestern Elkhart County, Indiana, from 1980 through 1989 to monitor hydrologic conditions and to provide information necessary for waterresources managers to evaluate the ground-water resources in this area. The area of study includes a closed industrial landfill and several areas of industrial and municipal pumping....

1991, Techniques of Water-Resources Investigations 06-A2
Removal of ground water by pumping from aquifers may result in compaction of compressible fine-grained beds that are within or adjacent to the aquifers. Compaction of the sediments and resulting land subsidence may be permanent if the head declines result in vertical stresses beyond the previous maximum stress. The process...
