Borehole from Abandoned Coal Mine Overwhelms Sulfur Creek

A view of Sulfur Creek in Adams Township, Cambria County below the Village of Dunlo and immediately downstream of one of the 8 major deep mine discharges in the Little Conemaugh Basin.

The borehole discharge has been measured at up to 1700 gallons per minute. The discharge is from deep mines abandoned many years ago. The pH of the water is below 3.4 and it has iron concentrations of up to 145 mg/l, Manganese of up to 19 mg/l and Aluminum up to 25.4 mg/l.

The Project

The Ebensburg Regional Office of the Pennsylvania Department of Environmental Protection Bureau of Mining and Reclamation, the Cambria County Conservation & Recreation Authority and the Cooney Bros. Coal Co. have recently embarked on a cleanup program of Sulfur Creek. The Authority has acquired ownership of the tract. The PADEP Mining Office has with the volunteer help of DaMariscotta (a Clarion, PA Consulting Firm specializing in the design of passive amd treatment systems) has developed a plan for remediation of the entire Sulfur Creek watershed. The borehole shown above is the largest problem. Cooney Bros. Coal Co. has begun limestone trenches and ponds which will test the treatment configuration on approximately 10% of the discharge. If the treatment is succesful for a one year period a larger scale system will be constructed. This project represents the first attempt in the area to apply passive treatment techniques to large borehole discharges. If this "experiment" works, we can have clean rivers.
