Pride Water Quality Assessment Report: I. Problems And Programs, Kentucky Water Resources Research Institute. University Of Kentucky

KWRRI Research Reports

This report provides an overview of the water quality problems and associated state and federal programs in the 40 counties that make up the PRIDE region. The 2000 Kentucky 305(b) stream assessment has identified over 1000 miles of impaired stream within the region. The major cause of pollution in the region is related to problems with pathogens. Much of these problems are related to straight pipes and failing septic and wastewater systems. It has been estimated that there are over 35,000 straight pipes and failing septic systems in the PRIDE region. A second major environmental impact in the region is …

Mining Geology Of Coals In Western Kentucky, Stephen F. Greb, David A. Williams

Map and Chart--KGS

Each of the most heavily mined coal seams in the Western Kentucky Coal Field, as indicated by analyses, mine visits, and discussions with mine inspectors and engineers, has its own roof and floor characteristics. Also, because roof rocks above several of the seams are laterally continuous (especially in the Carbondale Formation), roof characteristics related to rock type are often widespread and continuous between mines. This chart discusses the mining geology of three western Kentucky coal beds, highlighted on the stratigraphic column shown in Figure 1.

Additional mining obstacles that can affect all coal beds and roof strata are (1) tectonic …

Mining Geology Of The Lower Elkhorn Coal, Stephen F. Greb, Gerald A. Weisenfluh

Map and Chart--KGS

The Lower Elkhorn (and its equivalents) is one of the leading producers of coal in the Eastern Kentucky Coal Field with 12 to 18 million short tons of annual production between 1974 and 1996, according to the Kentucky Department of Mines and Minerals. Stratigraphically, the coal occurs in the lower part of the Pikeville Formation of the Breathitt Group (Fig. 1), which was previously part of the Breathitt Formation (Chesnut, 1992). The coal occurs from 150 to 300 ft above the base of a thick coarsening-upward sequence containing the Betsie Shale and from 250 to 450 ft beneath the base …
