Wilson Run Site

AMD Treatment

The Sewickley Creek tributary of Wilson Run parallels the Pennsylvania turnpike in the middle watershed area in Mt. Pleasant Township along route 819. Discharge from the abandoned Stewart mine entering Wilson Run contributes over 1,500 gpm.

Initial remediation of this site by the Sewickley Creek Watershed Association included increasing the oxidation process with the installation of a low volume air pump within an air shaft 10 to 15 feet below the water surface - this process precipitated the iron oxide before it entered Wilson Run. This system worked for a brief period of time , but iron oxide formed on and clogged the tubes within the air shaft and thus required extensive maintenance. Experimentation continued, and a new passive treatment system was installed. Iron oxide recovery is currently ongoing.

The Watershed Association meets at 7:00 pm on the third Thursday of every month at the lower level of the      J. Roy Houston Conservation Center (WCD Barn), 218 Donohoe Rd, Greensburg, PA 15601.
