Background/Objectives. This former central Pennsylvania manufacturing facility, now used for apartments, school, and offices, was impacted by chlorinated solvents from several potential source areas. Bedrock across the site is shallow and DNAPL likely drained through overburden into the fractured rock. A groundwater pump and treat system has been providing hydraulic control since 1995. The project objectives were to evaluate site status, update the conceptual site model (CSM), and interface with regulators to develop an achievable path forward and reduce off-site migration. Primary constituents of concern (COCs) present in groundwater include trichloroethylene (TCE) and 1,1,1-trichloroethane (TCA).
