Little Coon Run in Farmington Township (Clarion County, PA) is polluted by acid mine drainage. Three artesian well discharges account for a majority of the AMD pollution. This project implemented a remediation plan that targeted these three discharges for treatment and sealing. The primary funding was a $396,734 Growing Greener grant from PADEP Bureau of Abandoned Mine Reclamation to Farmington Township. Secondary support of approximately $40,000 was obtained the Office of Surface Mining’s Appalachian Clean Streams Program. Hedin Environmental (Pittsburgh, PA) managed the project and provided engineering and technical support to Farmington Township.
As a result of the plan a Growing Greener project to install the LC20D Passive Treatment System and plug the LC35D and LC40D artesian discharges was competed 2007. The Passive Treatment System has functioned well and stream restoration benefits are apparent in Little Coon Run.
