To address the environmental effects of coal mining in the Anthracite and Bituminous Coal Regions of Pennsylvania, it is important to understand the geology of these regions.  There are significant differences and similarities between regional-scale physiography and local-scale topography, geologic structure, stratigraphy and hydrogeology.  These factors all play a role determining the mining methods used to extract coal, defining abandoned mine land features such as drainage pollution, and evaluating water quality and quantity.


Dan Koury has served as the Watershed Manager for DEP's Pottsville District Mining Office since 1989. He has a B.S degree in Earth Science from PSU (1988).

Roger Hornberger has a B.S. in Landscape Architecture from Penn State (1972) and a M.S. in Geology from Penn State (1985). He worked for DEP and its predecessor DER from 1978 to 1987 as a hydrogeologist in Harrisburg and in Pottsville DMO as District Mining Manager from January 1987 to July 2006. He is now employed part-time on several projects and litigation cases.
