This 50-acre site includes a former chemical refining, packaging, manufacturing facility and an adjacent chromium ore processing facility, adjacent to a navigable waterway. Various portions of the site are regulated under Administrative Consent Orders, the New Jersey Industrial Site Recovery Act and CERCLA. DNAPL and various other COIs were found to be present in two former wastewater treatment lagoons, stormwater drainage ditches, river sediments, surface and subsurface soils, and groundwater. In addition, activities associated with the chromium ore operations had resulted in related impacts in near-surface soils. The selected remedy for the site included:
  • Steel sheet pile retaining wall / bulkhead
  • Fully-encompassing cement / bentonite slurry wall
  • On-site consolidation and capping of impacted soils and sediments
  • Remedy Selection and Regulatory Negotiations
  • Lagoon stabilization
  • River sediment removal and restoration
  • Capillary breaks for prevention of chromium vertical mobility
  • Wetlands mitigation
  • DNAPL / groundwater recovery and treatment
  • Building demolition
Construction is complete and a corresponding Remedial Action Report was submitted to the regulatory authorities.
Highlights
The successfully negotiated approach provided for on-site consolidation using the USEPA’s Area of Contamination Policy.
The consolidation approach has additionally left much of the site in suitable condition for future redevelopment.
