摘要：	Remediation of soil can be a long, difficult, and costly process. The combination of innovative technology, strong project management, close regulatory liaison, and the integration of a variety of remedial options turned an unexpected drum burial site into the successful completion of a highway access ramp. Buried drums containing hazardous polychlorinated biphenyl (PCB) waste were encountered directly in the path of a proposed highway access ramp during construction activities. Geophysical techniques such as ground-penetrating radar and magnetometry were used to define the horizontal and vertical extents of buried drums and waste. Field-testing kits that exploit immunoassay techniques were used to screen and segregate the excavated PCB-contaminated soils quickly and inexpensively and minimize the number of required postexcavation samples. Analysis of duplicate soil samples confirmed the accuracy of the field-testing kits before and during the remedial activities. Buried waste and soils containing hazardous concentrations of PCBs were excavated, loaded into trucks, and transported to an approved Toxic Substance Control Act facility. Approximately 7256 Mg (8,000 tons) of the remaining nonhazardous soil was used on-site as fill during the ramp construction. Careful planning of the work and the establishment of an informal but highly effective partnering relationship among all participants resulted in a remedial project that proceeded expeditiously with significant cost savings for the client. Ultimately, the ramp was constructed and the highway was opened to the public on schedule.
