BCWA constructed two passive treatment systems adjacent to the headwaters of Coal Pit Run, a tributary to the South Branch Blacklick Creek.  The systems are located north of Expedite Road, to the east of the village of Twin Rocks, in Blacklick Township, Cambria County.  Both systems were built in 2005.  The Lower Treatment System has been negatively impacted by some construction activities, which disrupted the flow into the system.  However, the Upper Treatment System continues to effectively treat water and enhances the water quality of the headwaters area of Coal Pit Run.  The Upper Treatment System consists of a collection pond, a vertical flow pond (containing crushed limestone and organic material) and a settling pond.    The Lower System was funded by the federal Office of Surface Mining (OSM) Watershed Cooperative Assistance  Program.  The Upper System was funded through an EPA Section 319 grant.   Reports, maps, photos, and water sampling results for the upper system have been posted on the Datashed website at https://www.datashed.org/project-coal-pit-run-upper-system.  Similar information and data on the upper system may be found at https://www.datashed.org/project-coal-pit-run-upper-system.

In addition to the two systems constructed by BCWA on Coal Pit Run, the PA Bureau of Abandoned Mine Reclamation constructed an open limestone bed further downstream on Coal Pit Run.  This system utilizes a sediment pond left over from a completed surface mine to treat part of a discharge from an abandoned deep mine.  Reports, maps, photos, and water sampling results for the upper system have been posted on the Datashed website at https://www.datashed.org/project-coal-pit-run-limestone-bed.
