An innovative passive treatment system was constructed at the H&D (Adobe) McIntire bond forfeiture mine site in 2011 to treat a highly acidic mine discharge with high concentrations of iron, aluminum, and manganese. The discharge is one of the worst quality discharges in the Slippery Rock Creek Watershed. The system intentionally utilizes innovative approaches such as low pH iron oxidation for removal and recovery, manganese removal and recovery, a mixed media Jennings Vertical Flow Pond, and a self-flushing automatic syphon as well as a solar powered SmartDrain limestone only Vertical Flow Pond. Prior to installation of the treatment system, the water had been left untreated since the 1990's when the H&D (Adobe) mining company forfeited their bonds. A land reclamation project was completed in 2006 by Quality Aggregates Inc. who was contracted by PA DEP BAMR under contract No BF 499-101.1 That project consisted of applying waste lime to specific "hot spot" areas of the sites that were identified by the PA DEP BAMR utilizing a conductivity study. The site is also currently being utilized by the Oakridge Hunting Dog Club
