- Description
- The Leadville Mine Drainage Tunnel is an 11,299 foot long mine drainage tunnel constructed between 1945 and 1956 to drain mine workings surrounding the town of Leadville, Colorado. Since March of 1992, Reclamation operated a water treatment plant to mitigate heavy metals contained in the mine drainage from the tunnel. The first several thousand feet of the tunnel penetrate alluvial soils and unstable fractured rock before entering competent granite and intersecting historic mine shafts. The tunnel has collapsed in several locations in unstable rock and soil downstream of the granite and mine workings preventing access to the upper portions of the tunnel. Reclamation is considering plugging the tunnel upstream of the collapses to limit clean groundwater migration into the tunnel flows sent to the treatment plant, increasing treatment efficiency and lowering treatment cost.
