U.S. Environmental Protection Agency, Region 3 Delaware, Maryland, Pennsylvania, Virginia, West Virginia and the District of Columbia >sr7?. ^7 HAVERTOWN PCP SUPERFUND SITE NEXT PHASE OF CLEANUP TO BEGIN Haverford Township, Delaware County, Pa Spring 2009 = INTRODUCTION • Backfill both excavated areas with clean soil and reveretate them. • Remove a portion of the sewer that is not sealed with yrout. • Install new monitoring wells and three new extraction wells that will withdraw shallow groundwater and pump it through an under- ground pipe back to the treatment plant. • Conduct ecological sampling to demonstrate habitat and fish recovery. The EPA will also establish institutional controls site-wide, in the Source Area and ROS, to ensure the environmental cleanup is not compromised. What to expect The EPA is about to start the next phase of cleanup work on two separate areas of the Havertown PCP Superfund site. The work should be completed by the end of the construction season. The two separate areas are known as the Source Area, which is the major source of the groundwater contamination, located at the former site of the Na- tional Wood Preservers. The site is alon<> I a<>lc Road across from the old Philadelphia Chewing Gum factory. The other area is known as the Recrea- tional Open Space (ROS), owned by the town- ship and located behind Rittenhouse Circle and adja- cent to Washington Avenue. It is not currently used as a recreational area. In the Source Area, the cleanup work includes the following steps: • Install an additional deep extraction well which will withdraw contaminated groundwater from deep below the ground surface for treatment. • Inject an aqueous, or water-based, solution into the deep contaminated aquifer to aid in drawing the groundwater to the surface for treatment. In the Recreational Open Space, the cleanup work includes: • Excavate soil in a SO-by-SO-foot area in the ROS, and in a narrow zone alon<> a nearby aban- doned sewer line. This is necessary because the sewer line had been transporting contaminated groundwater down to the ROS. • Heavy construction equipment bein<> used for both construction and excavation. • All work should take place during regular busi- ness hours, and traffic and/or noise may in- crease near the work areas. • Only a few homes, those that border the site, will be directly affected. Those residents will be contacted individually. Public Availability Session EPA officials will be on hand to answer the public's questions and comments.

It is surrounded by a mix of businesses, industries, parks, schools and homes. From 19+7 to 1963, the site was used by National Wood Preservers to treat wood products. The company allegedly disposed of diesel-type oil and pentachlorophenol, a wood preservative, in a well. The liquid wastes leached into nearby Naylor's Run, a small stream that flows through a residential area into the Delaware River. Liquid wastes were also spilled contaminating soil and groundwater in the area. The EPA first became involved with the Havertown PCP site in 1976 and has completed a number of cleanup measures to protect the surrounding community and environment. Some of those measures included: • Installation of an oil-water separator to reduce oil in the storm sewer that was discharging to Naylor's Run. • Removal of on-site drums and hazardous waste. • Installation in 1991 of an on-site pump-and-treat sys- tem to address groundwater in the shallow aquifer. The system was recently upgraded to increase its ca- pacity.
