The effectiveness of natural riparian grass filter strips in removing sediment and agricultural chemicals from surface runoff was studied using no-tillage and conventional-tillage erosion plots. Runoff from the tillage plots was directed onto 4.57, 9.14, and 13.72 m (15, 30, and 45 ft.) length filter strips, where the inflow and outflow concentrations and sediment size distributions were measured. Trapping efficiencies for sediment and agricultural chemicals typically ranged near or above 90 percent, mainly because of high infiltration rates. The filters also significantly reduced peak discharge concentrations, which reduced the impact of sediment and agricultural chemicals on receiving surface waters.
Chemical And Statistical Analysis Of A Sampled Interval In The Camp Nelson Limestone (Upper Ordovician) Madison County, Central Kentucky, Garland R. Dever Jr., Warren H. Anderson, Henry E. Francis, O. Barton Davidson, Mark F. Thompson

The Camp Nelson Limestone of the High Bridge Group (Upper Ordovician) is mined at seven sites in central and north-central Kentucky for industrial, construction, and agricultural uses. As part of a regional investigation of its chemical characteristics, a 67-foot section in the upper Camp Nelson, which is being mined at Boonesborough, Madison County, was sampled for major-element analysis.
The upper Camp Nelson in the Boonesborough Mine consists of two zones (23 and 30 feet thick) of low-silica stone (4 percent or less total SiO2) separated by a 14-foot section of slightly argillaceous limestone with an average silica content …
Limestone And Lime For So2 And Pollutant Control In The Ohio Valley, James C. Cobb, Garland R. Dever Jr.
Limestone And Lime For So2 And Pollutant Control In The Ohio Valley, James C. Cobb, Garland R. Dever Jr.
Information Circular--KGS
The purpose of this conference is to emphasize the importance of limestone resources for controlling SO2 emissions from coal-fired power plants. We have brought together experts from utilities to describe important factors in limestone performance in scrubbers and from the stone industry to describe important factors in limestone and lime production. Conference speakers include also representatives from research institutes, equipment manufacturers, government agencies, and geological surveys.
Available Coal Resources Of The Salyersville South 7.5-Minute Quadrangle, Magoffin County, Kentucky, Robert E. Andrews, Gerald A. Weisenfluh, John K. Hiett, Richard E. Sergeant

Coal resources available for mining have been estimated for the Salyersville South Quadrangle, which is located in the Licking River Coal Reserve District of the Eastern Kentucky Coal Field. Nine coal beds within the quadrangle are potentially mineable and constitute the basis of these resource estimates. Seven of these beds have been commercially developed, but only five have produced more than 1 million tons: from youngest to oldest, the Skyline A, Lower Broas, Lower Peach Orchard, Middle Peach Orchard, and Upper Peach Orchard. A computerized Geographic Information System was used to calculate estimates of original, mined-out, and remaining resources, as …
Ground Water In The Kentucky River Basin, Daniel I. Carey, James C. Currens, James S. Dinger, James A. Kipp, David R. Wunsch, Philip G. Conrad

Most private wells in the Kentucky River Basin are in unconfined or semi-confined bedrock aquifers. Within these aquifers, high-yield zones are irregularly distributed. The most productive wells are drilled into fractured bedrock and alluvium along the Kentucky River floodplain. The data indicate that ground water acts as a buffer to peak and low flows in Kentucky River Basin streams. At current withdrawal rates, ground-water usage does not seem to have an adverse impact on the Kentucky River. Privately owned ground-water sources supply approximately 135,000 people living in the basin-approximately 19 percent of the total population and 36 percent of the …
