This project resulted from renovation work, involving exterior building envelope restoration work, that caused Poly-Chlorinated Biphenyl (PCB) -laden debris (in the form of waste caulk) to fall throughout the Federal courthouse plaza, including into the playground of the employee’s day care center. This project had a sensitive population at risk, and numerous concerned parties. The falling debris resulted in site-wide contamination above background levels and both state and Federal regulatory triggers. The regulatory framework included satisfying New Jersey Department of Environmental Protection (NJDEP) and Federal Toxic Substances Control Act (TSCA) clean-up requirements simultaneously. Tectonic provided reviews, inspection, and testing services to delineate the extent of residual PCBs.
The site is located within a Federal compound of a large city; this, and the security issues made the Remedial Investigation (RI) a challenge. Tectonic also ensured the testing regimens conformed to the TSCA evaluation procedures and all samples were analyzed at a NJ-authorized contract laboratory. Tectonic delineated the horizontal and vertical extent of PCBs in the soil and unitary play surface.
