The General Services Administration (GSA) retained Tectonic to provide environmental testing and remediation services. Building restoration work caused Poly-Chlorinated Biphenyl (PCB) -laden debris (from waste caulk) to fall throughout the Federal courthouse plaza and playground of the employee’s day care center. This project had a sensitive population at risk and the falling debris resulted in site-wide contamination above background levels with both state and Federal regulatory triggers.

• Review, test, and evaluate extent of residual PCBs.
• Remedial Investigation (RI)
• Delineated and managed remediation of the PCBs .
• Regulatory framework included satisfying New Jersey Department of Environmental Protection
  (NJDEP) and Federal Toxic Substances Control Act (TSCA) requirements simultaneously.

The site is within a large city; this, and the security issues made the Remedial Investigation a challenge.
