Aerial view showing the three parcels of the<unk>  Superfund Site The site is divided into three parcels: an<unk>  waste pile, a reservoir and a closed park. The<unk>  waste pile was approximately and covered of a property. The reservoir was used for process water for manufacturing and is approximately in size on a lot. The berm of the reservoir was constructed from<unk>  shingles, millboard and soil. The Whitpain Wissahickon Park was used as an<unk>  waste dump and then filled in and converted for usage as a park from 1973 to 1984 when it was closed and fenced-in due to<unk>  contamination. The site also includes portions of Wissahickon Creek, Tannery Run Creek and Rose Valley Creek which run adjacent to the three parcels. The site is located in a densely populated borough with approximately 6,000 people living within . It is the second largest<unk>  dump site in the United States. The U.S. Environmental Protection Agency (EPA) conducted an emergency removal action in 2008 which included capping the<unk>  waste pile with a geotextile material and 2 feet of clean material and stream bank stabilization of the three creeks. The EPA added the site to the Superfund National Priorities List in April 2009. The total cost of site clean-up was approximately $26 million. The site is currently being monitored on a quarterly basis and after significant weather events to ensure the integrity of the cap and stabilized stream banks. A five-year review will be completed by the EPA in 2022.
