Many Brownfield sites contain areas where intrusive investigations cannot be readily conducted due to unstable ground conditions. Described in this paper are the means used at the Former Oxford Paper Mill Site in Lawrence, Massachusetts, to assess and remediate an unstable area containing asbestos and elevated levels of PCBs. An area totaling approximately 35 feet wide by 200 feet long contained many voids created by partial demolition of basements and subsequent backfilling after the mill ceased operations in 1974. It was known that PCB and asbestos contamination was present in this area, but the nature and extent was unknown. This paper describes the use of remote intrusive investigations combined with assumptions regarding site characterization leading to a final assessment of soils in place, and that was utilized to successfully address the problem.
