KD Surface Mine No. 1 - Aerial 1

Keystone West Virginia, LLC. operates the KD Surface Mine No. 1 in Kanawha County, as seen in this aerial photo on March 27, 2025.

The West Virginia Department of Environmental Protection has found a seep of polluted water likely was caused by mining near Kanawha State Forest and has negatively affected water quality in a tributary of Lens Creek, findings conservationists say confirm their allegations about the cause of area acid mine drainage near Marmet.

But the DEP has downplayed the report containing those findings, despite its long history of determining environmental violations on the 160-acre mine permit in question near the state forest.
