PROJECT NAME: Captain Jack Superfund Reclamation
OWNER: CDPHE – Division of Mining and Reclamation
LOCATION: Ward, Colorado
FACILITY TYPE: Former Gold & Silver Mine
Project Background: The Captain Jack Superfund Site, located approximately 1.5 miles south of Ward Colorado, was a gold and silver mining site from 1861 to 1992. Over this time more than 100,000 CY of mine tailings were generated. The EPA added this site to its National Priorities List in 2003 and designated a Superfund Site in 2008
Scope of Work:
Scope of Work:
Colorado Cleanup was selected by the CDPHE to perform the Surface Remedy. This work was designed to clean up the surface waste, consolidate the mine waste, and stop the contamination caused from dust and leachate into Lefthand Creek and the surrounding environment.
CCC demolished and removed the former mill buildings. We consolidated over 45,000 CY of mine waste into an on-site repository, and re-graded the remainder of the waste to 3:1 slopes. An upper and lower sediment pond were formed to allow the contaminants flowing from the Big Five Adit drainage to settle out.
Additionally, over 45,000 CY of clean fill was harvested, screened and placed to provide a clean cover cap over the mine waste. This fill was screened into 2 inch minus material and amended to create a growth medium. Rip rap and rock cover were also harvested and placed on site. Over ten acres were seeded and mulched. Lefthand Creek was restored with boulder features and planted with willow cuttings. CCC re-graded California Gulch Road, laid sod and planted native conifer trees.
