WINGFIELD PINES

The Wingfield Pines passive treatment system treats an iron-contaminated discharge from a long abandoned underground coal mine. The system is located on Allegheny Land Trust property in Upper St Clair (a suburb of Pittsburgh). Treatment is obtained through an innovative aeration system, a series of settling ponds, and a constructed wetland. The design has educational and artistic themes that visually communicate the remediation process. Funding was provided by the PA DEP Bureau of Abandoned Mine Reclamation, the US Office of Surface Mining, and the Foundation for Pennsylvania Watersheds.
