Soil & Terrain Characteristics

Greene County sits on the Waynesburg Hills section of the Allegheny Plateau with soils derived from Pennsylvanian and Permian sandstone, shale, limestone, and coal measures. The rolling terrain has clay-rich soils that are often poorly drained. Monongahela River and Tenmile Creek valleys have deeper alluvial deposits. Both surface and deep mining have significantly disturbed soil profiles.

County-Specific Considerations

Greene County is Pennsylvania's southwesternmost county and has extensive active and legacy coal mining operations. Both longwall mining and conventional deep mining have caused surface subsidence affecting structures and septic systems. The county is also a center for Marcellus and Utica Shale natural gas development. Nearly all rural properties rely on on-lot systems. Waynesburg is the county seat and one of few areas with municipal sewer.
