Current Activities

Design and construction of the site-wide remedy as described in the Record of Decision issued by the U.S. Environmental Protection Agency (USEPA) on September 27, 2012 is underway.

Construction of the bedrock and overburden groundwater containment, extraction, treatment, and reinjection system, a major component of the site-wide remedy, is complete and the system is fully operational. The dedicated on-site groundwater treatment facility, located on Polhemus Lane in Bridgewater, will be operated long-term and groundwater will be monitored pursuant to requirements set forth by USEPA and New Jersey Department of Environmental Protection (NJDEP).

Pre-design and design activities related to the site-wide soils remedy, including design of the stabilization/solidification treatment process for waste materials located in Impoundments 3, 4 and 5, continue.

The New Jersey Water Supply Authority has initiated a four-year project to dredge a 10-mile section of the Delaware and Raritan (D&R) Canal within Franklin Township. Sediment that is removed from the D&R Canal and verified to be clean will be dewatered and delivered by truck to the American Cyanamid Superfund Site for beneficial reuse as subgrade material for the site-wide soil remedy pursuant to USEPA and NJDEP oversight. Deliveries will occur between September and early spring during each of the next two years. At peak times, up to 80 truckloads of materials will be delivered to the site per day.

Impoundments 1 and 2

On September 25, 2018, the USEPA issued a Record of Decision (ROD) for Operable Unit 8 (OU8), commonly referred to as Impoundments 1 and 2. USEPA and Wyeth Holdings LLC (WH) executed an Administrative Order on Consent on September 30, 2019 that allows WH to move forward with design and engineering for the remedy as described in the ROD. During the design phase, WH intends to perform a demonstration project to help refine the process of excavating, dewatering and disposing of the impoundment materials.

Impoundment 8 Facility

The Impoundment 8 Facility, located on Polhemus Lane, was designed to receive material exclusively from other areas of the Site as part of a multi-phase remediation program. The facility is regulated under the Resource Conservation and Recovery Act (RCRA) and work is addressed with oversight by the NJDEP, and the concurrence of the USEPA.

Less than 40% of the facility has been used to receive materials remediated during earlier remedial actions on the site, with the remaining capacity unused. Based upon USEPA’s selected remedies, the Impoundment 8 Facility will not receive any more material. Therefore, Wyeth is moving forward with plans to implement a final closure and post-closure care plan in accordance with RCRA regulations.
