Coal mining and industrial activities have caused significant environmental degradation in the Appalachian region, impacting both the land and its waterways.1

Impact on Land

Surface mining, particularly mountaintop removal mining, has caused irreparable alterations to the topography of the Appalachian landscape. Historically, mining operations left behind "lunarlike" landscapes characterized by barren spoil banks—piles of loose, porous overburden that are difficult to revegetate. These areas often suffer from high acidity due to the oxidation of iron sulfides, which inhibits plant growth and complicates land reclamation efforts.234

Impact on Waterways

Mining operations have severely affected water quality through the discharge of sediment and chemical pollutants.2
* Sedimentation: Streams are frequently clogged with sediment produced by exposed mining surfaces and improperly dumped waste.2
* Acid Mine Drainage: The leaching of sulfuric acid and iron sulfates from exposed rock creates acidic conditions that reduce the diversity of plants and animals in nearby ecosystems.2
* Contamination: Toxic elements leached from coal and adjacent rocks can contaminate groundwater supplies.2
