History & Location
The Former Hackensack Gas Works Site is located in the southern portion of Hackensack, New Jersey, along the western bank of the Hackensack River. The site was used as a former manufactured gas plant (MGP) from 1867 to 1908 and is comprised of several Areas of Concerns (AOCs); however, scope of work for this project was limited to Area E. The area consists of impacted sediments and surface water within the Hackensack River and adjacent Brosses Creek.
Significant Project Features
- Excavation, transportation, and disposal of more than 12,000 CY of MGP-contaminated sediment
- Successfully utilized custom-fabricated hopper scows and DOS scows to move and dewater sediment prior to T&D
- Transported material in DOS scows using tugboats, via the Hackensack River, to the designated disposal facility
- Sevenson completed over 9,276 safe work hours without a lost-time incident
