Advertorial Remediation in the Lower Passaic River: A Blueprint for Environmental and Community Success Achieving what the USEPA calls “a significant step in the cleanup and restoration of the Lower Passaic River,” ARCADIS has led the removal and disposal of 40,000 cubic yards of sediment known to contain some of the highest concentrations of dioxins and other constituents found in the river. Despite the challenges of a complex urban setting, ARCADIS has successfully remediated a two-acre area of the Passaic River adjacent to the Diamond Alkali Superfund Site – creating jobs and a cleaner environment for the residents of Newark, New Jersey. The project took more than 18 months to design and plan due to the challenging urban and physical setting of the site. Beginning in October of last year, a sheet-pile enclosure was installed in the river to contain resuspended sediment generated during removal activities. Actual dredging began in March 2012, with the excavated material pumped a short distance downstream via floating hydraulic pipeline to the upland processing facility. There, the sediment slurry was screened to remove coarse solids. The fine-grained material was then dewatered using state-of-the-art membrane presses, placed into sealed containers, and transported for disposal via truck/rail to a Subtitle C landfill or an incinerator (depending on the specific waste category). Air monitoring was performed in the work area, at the upland processing facility and in two nearby residential areas throughout the dredging and sediment processing activities. Process water was treated using a temporary water treatment system and discharged back to the Passaic River. Following removal activities, the area within the sheet-pile enclosure was backfilled and restored to its original grade. In an effort to include local community in the cleanup effort, ARCADIS/Tierra Solutions, Inc. worked closely with the USEPA to hire Newark residents. Fifteen of the more than 500 applicants completed the USEPA Superfund Job Training Initiative (SuperJTI) and worked for the project, receiving skills and experience that will stay in the community long after project completion. In addition, local intermodal transport facilities benefited from the 1,450 site containers transferred from truck to railcar, and project dollars were spent locally whenever possible. A Community Hotline and Investigation/Response Process (CHIRP) handled inquiries in three languages. As a result of the extensive hazard management measures developed with the community via the deliberative Community Health and Safety Plan (CHASP) process, there were no disruptions to project operations or community quality of life from odor, noise, navigation or traffic issues. Safety First ARCADIS maintained a strong focus on health and safety throughout the project, achieving a superior H&S record: more than 128,000 worker hours without a major injury. ARCADIS staff even handed out ice-cream-cone-shaped stickers to encourage and reward safety behavior as part of an “I Scream for Safety” program. The stickers adorned hard hats and parking passes, serving as a fun and effective way to promote teamwork in creating a safe workplace. “This project exemplifies the client focus; operational excellence; and market, technology and H&S leadership for which ARCADIS is renowned,” Bob Romagnoli, ARCADIS Senior Vice President and Engineer of Record for the project, stated. “It also exemplifies Tierra Solutions’ commitment to the health and restoration of the Passaic River and to the quality of life in the local community. It provides a blueprint for how numerous parties with multiple objectives can come together to produce a highly successful project.” For more information contact Community Engagement with Project Results Local residents had waited decades for action, and the project has drawn a great deal of positive attention and praise. Early engagement with the community and regulatory agencies resulted in meaningful results for both residents and project operations.
