Gladden Acid Mine Drainage Treatment Plant

The Gladden acid mine drainage (AMD) treatment plant has eliminated one of the largest impairments to the Chartiers Creek watershed by continually pumping and treating over one million gallons of AMD daily and discharging the treated water to Millers Run. The treatment plant will ultimately restore four miles of Millers Run and four miles of Chartiers Creek to a warm water, trout-stocked fishery with improved recreational uses. Millers Run is on the Pennsylvania Fish & Boat Commission stocking list upstream of the discharge. The sections of both streams that will be restored flow past a number of parks and development projects and are visible from Interstate 79 in Allegheny County.
