Experience Highlights

Managed a large food manufacturer’s catastrophic break in their underground heating oil lines for their building.  A significant heating oil related leak reached the Passaic River and required cleanup of the storm system, source area, and spill into the river via product skimming of the river and steam cleaning the riverbanks.  He managed the design and implementation of a combination product recovery, ground water treatment system and soil bioventing system to remediate the contamination.  These actions lead to a full No Further Action determination by NJDEP for the property.

Project Director for environmental investigations at a former industrial site being developed into upscale residential townhouses.  Prepared the Remedial Investigation Reports, and Remedial Action Workplans to remediate groundwater impacted by MTBE.  Managed the community outreach along with the successful remediation.

Managed the chromium remediation program for cleanup of 45 residential sites in the center of Jersey City, New Jersey.  He investigated and implemented the detailed site plans to sample and delineated the contamination then oversaw the installation of 50 monitoring wells, 1,500 boring logs, and collection of 20,000 samples for analysis.  The subsequent remediation was completed under budget and on schedule with the signed consent order with the State.
