Hydrogeology and simulation of ground-water flow in the Ohio River alluvial aquifer near Carrollton, Kentucky
Michael D. Unthank
1999, Water-Resources Investigations Report 98-4215
The alluvial aquifer near Carrollton, Kentucky, lies in a valley eroded by glacial meltwater that was later part filled with outwash sand and gravel deposits. The aquifer is unconfined, and ground water flows from the adjacent bedrock-valley wall toward the Ohio River and ground-water withdrawal wells. Ground-water-level and Ohio River...

1999, Fact Sheet 104-98
In 1991, the U.S. Geological Survey (USGS), in cooperation with the U.S. Department of Agriculture (USDA) and the Texas State Soil and Water Conservation Board, began a study to evaluate the effects of agricultural best-management practices on surface- and ground-water quantity and quality in the Seco Creek watershed. The USGS...
Water-quality assessment of south-central Texas — Comparison of water quality in surface-water samples collected manually and by automated samplers
Patricia B. Ging
1999, Fact Sheet 172-99
Surface-water sampling protocols of the U.S. Geological Survey National Water-Quality Assessment (NAWQA) Program specify samples for most properties and constituents to be collected manually in equal-width increments across a stream channel and composited for analysis. Single-point sampling with an automated sampler (autosampler) during storms was proposed in the upper part...
Simulation of ground-water flow and movement of the freshwater-saltwater interface in the New Jersey coastal plain

William H. Mullins
1999, Water-Resources Investigations Report 99-4178
The lower Boise River, between Lucky Peak Dam and the mouth of the river near Parma, Idaho, is adversely affected by various land- and water-use activities. To assess the biotic integrity of the river and the effects of environmental perturbations on aquatic community structure, and to provide a baseline from...
Occurrence, distribution, and trends of volatile organic compounds in the Ohio River and its major tributaries, 1987-96
Robert F. Lundgren, Thomas J. Lopes
1999, Water-Resources Investigations Report 99-4257
The Ohio River is a source of drinking water for more than 3 million people. Thus, it is important to monitor the water quality of this river to determine if contaminants are present, their concentrations, and if water quality is changing with time. This report presents an analysis of the...
