Superfund Record of Decision (EPA Region 3): Henderson Road NPL Site, Upper Merion Township, Pennsylvania (Second Remedial Action), September 1989

摘要

The Henderson Road site is a 7.6-acre site in Upper Merion Township, Pennsylvania. O'Hara Sanitation Company, Inc. has used the site for waste storage, waste recycling, vehicle maintenance, and parking and office facilities since 1974. The site is bounded by the Pennsylvania Turnpike, the Conrail property including train tracks, Henderson Road, and Frog Run. In 1974 William J. O'Hara, Inc. began landfilling trash and construction debris on central and eastern portions of the site until 1984. The first operable unit for the site, as described in a June 1988 Record of Decision, included pumping and treatment, using air strippers, of contaminated ground water. This will be accompanied by additional characterization of the injection well, excavation of oil pit sediment if found, and removal of significant waste within the well.
