U.S. Geological Survey research in radioactive waste disposal - Fiscal years 1986-1990
1991, Water-Resources Investigations Report 91-4084
The report summarizes progress on geologic and hydrologic research related to the disposal of radioactive wastes. The research efforts are categorized according to whether they are related most directly to: (1) high-level wastes, (2) transuranic wastes, (3) low-level and mixed low-level and hazardous wastes, or (4) uranium mill tailings. Included...
Changes in chloride concentration in water from municipal wells that tap aquifers in rocks of Cambrian and Ordovician age in northeastern Illinois, 1915–84
G. O. Balding
1991, Water-Resources Investigations Report 90-4116
During the past few decades, several municipalities in northeastern Illinois have noted increases in the salinity of water from wells that tap aquifers in rocks of Cambrian and Ordovician age. The municipalities have discontinued the use of, or sealed-off sections of, those wells. The aquifers involved include the Ancell, the...
Water withdrawals in the Black Warrior-Tombigbee Basin and Alcorn County, Mississippi, 1985-87
N. L. Barber
1991, Water-Resources Investigations Report 90-4061
Public-supply and industrial water withdrawals were inventoried for the Mississippi part of the Black Warrior-Tombigbee Basin and for Alcorn County, Mississippi. The study area, located in the northeastern part of the State, is largely forested or agricultural land, with some industries near the larger towns. A water-resource capacity analysis was...
Wetland sedimentation and vegetation patterns near selected highway crossings in West Tennessee
D.E. Bazemore, C.R. Hupp, T.H. Diehl
1991, Water-Resources Investigations Report 91-4106
Wetland sedimentation and vegetation patterns at 11 highway crossings in West Tennessee were studied from 1987 to 1989. The purpose of the study was to investigate potential adverse effects of highway crossings on wetlands. Sedimentation rates, determined from root-burial depths, were highly variable. Average rates offine-grained deposition ranged from 0.005...
Ground-water hydrology and the effects of vertical leakage and leachate migration on ground-water quality near the Shelby County landfill, Memphis, Tennessee
M. W. Bradley
1991, Water-Resources Investigations Report 90-4075
An investigation of potential leakage of leachate from the Shelby County landfill near Memphis, West Tennessee, was conducted during 1986-87. The migration of leachate from the landfill to the shallow alluvial aquifer system and the potential leakage to the deeper confined Memphis aquifer of Tertiary age were investigated. A network...
