Site Description

From 1947 to 1991, National Wood Preservers ran a wood treatment operation on this site in Havertown, PA. The company reportedly disposed liquid wastes contaminated with pentachlorophenol (PCP) into a well leading to the groundwater under the plant. The liquid wastes leached into nearby Naylor's Run, a small stream that flows through a residential area and eventually into the Delaware River. Spilled liquid wastes also contaminated the soil and groundwater in the area. The groundwater, surface water, and soil are contaminated with PCP, arsenic, dioxins, volatile organic compounds (VOCs), and petroleum hydrocarbons.

Current Site Status and Cleanup Actions to Date

  • EPA is currently conducting a RI/FS at the site for the deep groundwater, the Residential Open Space (ROS) area, and the soils and sediments of Naylors Run. Through the progression of the RI/FS, EPA has identified a new area of contamination, the ROS area, as well as an area of source material. Both of these findings warrant additional investigation before the RI/FS can be concluded.
  • EPA installed oil/water separator at discharge to Naylors Run.
  • In April 1994, EPA removed about 97,000 tons of liquids, 55 gallons of solids, and 60 tons of sludge B all containing hazardous wastes. Thirty tanks were cleaned, cut up, and recycled. EPA also demolished the wood treatment building, removed an underground storage tank, and removed all the demolition debris from the site.
  • In 1996, EPA demolished the vacant Lobb Lumber Building, located on an adjoining, contaminated property.
  • In November 1996, EPA installed single barrier synthetic flexible membrane cap on the former National Wood Preservers property to eliminate exposure risk to contaminated soils.
  • In June 2001, EPA successfully installed shallow groundwater pump and treat facility to capture and clean contaminated water in the shallow aquifer.
  • In May 2004, EPA identified, cleaned and sealed old abandoned sewer line that ran from the Philadelphia Chewing Gum Company through the Rittenhouse Circle development.

Current Funding Status

  • EPA has spent approximately $12 million for the Remedial Action (RA) conducted to date at the site.
  • EPA has spent an additional $6.5 million for a Removal Action.
  • EPA is funding the Long-term RA to operate the treatment facility at a rate of approximately $700,000 per year.
  • The site was still in the RI/FS stage, and not ready to begin construction in Fiscal Year 2004.

Key Accomplishments

  • In November 1996, installed single barrier synthetic flexible membrane cap on the former National Wood Preservers property to eliminate exposure risk to contaminated soils.
  • Installed shallow groundwater pump and treat facility to capture and clean contaminated water in the shallow aquifer. The facility was completed in June 2001 and has been operating successfully since start-up.
  • Identified, cleaned and sealed old abandoned sewer line that ran from the Philadelphia Chewing Gum Company through the Rittenhouse Circle development. The sewer project was completed in May 2004.
  • Completing a Remedial Investigation and Feasibility Study (RI/FS) to select a permanent cleanup remedy for the Site.
