Coal Pit Run Systems

There are two small abandoned mine discharges in the headwaters of the South Branch Black Lick Creek.  Both of these are located along the banks of Coal Pit Run.  The upper passive treatment system consists of a collection pond, a vertical flow pond (containing crushed limestone and manure) and a settling pond.  The lower system consists of a vertical flow pond and a wetland.  These systems are designed to neutralize the acidity, reduce sulfate and filter out the precipitated metals.  Both systems were constructed in 2005 funded by OSM Watershed Cooperative Assistance (Lower) and EPA Section 319 (Upper) and are located in Blacklick Township, Cambria County.  Reports, maps, photos, and water sampling results have been posted on the Datashed website at
