The Havertown PCP site is located in Havertown, Haverford Township, Delaware County, in southeastern Pennsylvania. The site contamination was first discovered in 1962 when the Pennsylvania State Department of Health became aware of contaminants in Naylors Run and attributed the source of PCP and dioxin contamination to the disposal practices of a nearby wood treating facility. Investigation and remedial activities have included the removal of existing waste from the site, treatment of effluentdischarging from the existing storm sewer, installation of an oil/water separator, off-site disposal of generated wastes, installation of a cap over soils impacted by dioxin, and operation of an interim P&T system, which began operation in 2001. This OSE focused on the operating interim P&T system but also considers potential enhancements to this system for addressing deeper ground water contamination as part of the final remedy for Operable Unit 3 (OU3).
