Central New Jersey

Project at a Glance:

• Investigation and remediation of large manufacturing facility that formerly made construction adhesives.
• Environmental concerns included arsenic-contaminated soil, which was addressed under New Jersey’s Industrial Site Recovery Act (ISRA).
• Arsenic-contaminated soil impacted on-site wetlands that were upgraded and restored.

Arsenic contaminated soil extended into wetlands areas. The project required the identification of wetlands, obtaining wetlands permits from the NJDEP, and from the U.S. Army Corp of Engineers. A wetlands restoration plan was prepared and implemented under the wetlands permit.

Whitman faced many challenges during the course of this project, including excavating soils up to a stream, and the removal of subsurface railroad siding along the length of the excavation of the wetlands.

The pre-excavation wetlands were of low to intermediate value and consisted of primarily common reed. Under the restoration plan, a diversified species of wetlands plants were planted and nourished to enable the wetlands to be upgraded and sustained for future ecological benefits.

Whitman was successful in causing minimum interference to the owner’s operations throughout the duration of the remediation.
