Kentucky River Basin Water Quality Assessment Study, L. Ormsbee, L. Jarrett, B. Perkins Jan 1998

Kentucky River Basin Water Quality Assessment Study, L. Ormsbee, L. Jarrett, B. Perkins

KWRRI Research Reports

The current report summarizes the work associated with the construction, calibration, and application of the CE-QUAL-W2 water quality model to the Kentucky River. In applying the model to the Kentucky River System, the primary objective was to assess the impact of the operation of low-level control valves on water quality of the Kentucky River. This was accomplished by modeling the impact of the valves for low flow conditions associated with the 1930 drought of record along with projections for the year 2020. The results of this study indicate that for the modeled scenario, the proposed valves can be used to …


Development Of A Kentucky Cso Database, L. Ormsbee Jan 1998

Development Of A Kentucky Cso Database, L. Ormsbee

KWRRI Research Reports

This report provides an overview of several products developed for the management of CSO data for the state of Kentucky. These products have been developed in fulfillment of the Memorandum of Agreement No. 13814 between the University of Kentucky and the Environmental Protection Cabinet. The developed products include: 1) an overall management structure, 2) a stand-alone data management computer program, 3) background maps for each CSO city, 4) a customized Access database management environment, 5) a computer program for automating monthly CSO discharge monitoring reports, and 6) a customized Arcview 3 project for visualization and management of physical CSO datasets.


Mineral And Fuel Resources Map Of Kentucky, Warren H. Anderson, Garland R. Dever Jr. Jan 1998

Mineral And Fuel Resources Map Of Kentucky, Warren H. Anderson, Garland R. Dever Jr.

Map and Chart--KGS

The production of minerals and fuels in Kentucky is a multibillion dollar industry. Historically, coal, oil, natural gas, limestone, sand and gravel, clay, fluorite, barite, lead, iron, phosphate, zinc, and brines have been produced in the State. These resources have greatly influenced the development of Kentucky by providing raw materials for the early settlers who settled the State and for current industrial and economic development. Electrical power for homes, businesses, and factories; materials for constructing houses, buildings, automobiles, and roads; and products we consume in everyday life come from the earth's mineral and fuel resources.


Use Of Algal And Macroinvertebrate Indicators To Assess The Impact Of Agricultural Practices On Surface Water Quality In The Mammoth Cave National Park Region, Kentucky, Jeffrey D. Jack Jan 1998

Use Of Algal And Macroinvertebrate Indicators To Assess The Impact Of Agricultural Practices On Surface Water Quality In The Mammoth Cave National Park Region, Kentucky, Jeffrey D. Jack

KWRRI Research Reports

The karst aquifer underlying the Mammoth Cave area supports a unique and diverse cave aquatic ecosystem as well as providing the principal source of drinking water for many local residents of the region. This unique and fragile ecosystem is surrounded by one of the most intensively used agricultural areas in the Commonwealth with more than 80% of the surrounding region used in beef, dairy, burley tobacco and alfalfa production. Agricultural practices resulting in run-off of pollutants into the aquifer via sinkholes and sinking streams have a pronounced impact on an important drinking water source and on the cave ecosystem. The …


Solute And Bacterial Transport Through Partially-Saturated Intact Soil Blocks, Edmund Perfect, Mark S. Coyne, Michael C. Sukop, Gerald R. Haszler, Virgil L. Quisenberry, Ligia Bejat Jan 1998

Solute And Bacterial Transport Through Partially-Saturated Intact Soil Blocks, Edmund Perfect, Mark S. Coyne, Michael C. Sukop, Gerald R. Haszler, Virgil L. Quisenberry, Ligia Bejat

KWRRI Research Reports

Steady-state transport of water, chloride and bacteria was measured through intact blocks of Maury and Cecil soils, under partially saturated conditions. Major objectives were to determine if transport occurs uniformly or via preferential flow paths, and if soil physical properties could be used to predict breakthrough. The blocks were instrumented with TDR probes and mounted on a vacuum chamber containing 100 cells that collected eflluent. After each experiment the blocks were sampled for soil physical properties. The fluxes showed no spatial autocorrelation and the eflluent variance was not statistically different between soils. Less than 3% of the influent bacteria appeared …


Spatial And Temporal Variability In Seepage Between A Contaminated Aquifer And Tributaries To The Ohio River, Alan E. Fryar, David L. Brown, David B. Wenner, Todd C. Rasmussen, Eric J. Wallin Jan 1998

Spatial And Temporal Variability In Seepage Between A Contaminated Aquifer And Tributaries To The Ohio River, Alan E. Fryar, David L. Brown, David B. Wenner, Todd C. Rasmussen, Eric J. Wallin

KWRRI Research Reports

Because interactions between ground water and tributaries may influence contaminant loading to rivers, we delineated seepage along Little Bayou and Bayou Creeks in McCracken County, Kentucky, during a two-year period. From the Paducah Gaseous Diffusion Plant, on the divide between the creeks, trichloroethene and technetium-99 plumes extend several km toward the Ohio River. Gaining conditions occur where the creeks are incised into coarse sediments in the river's flood plain. Such conditions were marked by upward hydraulic gradients within the bed; maximum specific discharge (q) > 0.24 m d-1; relatively narrow ranges of stream, piezometer, and bed temperatures; relatively cool …
