This website serves as a source of news and information for the residents of Bridgewater, Bound Brook, and surrounding communities regarding the remedy and restoration of the American Cyanamid Superfund Site owned by Wyeth Holdings LLC (WH). Pfizer Inc assumed responsibility for the site on October 15, 2009, through its larger acquisition of Wyeth. Although Pfizer never operated at the site, Pfizer takes its responsibility seriously and is aggressively working to improve site conditions.


Under the oversight of the U.S. Environmental Protection Agency (USEPA) and the New Jersey Department of Environmental Protection (NJDEP), Pfizer is working to accomplish four key objectives:

  1. To implement a remediation program that is protective of human health and the environment;
  2. To ensure that site remediation activities facilitate reuse and redevelopment of portions of the property;
  3. To preserve and enhance the ecological assets of the property in a manner that creates value in the Raritan River regional ecosystem; and
  4. To position the property as an asset to the local community and the region.


Pfizer continues to actively work with USEPA, NJDEP, and other stakeholders, to move the site remediation process forward. We are committed to implementing a site restoration program that is responsive to stakeholder input and returns the property to productive use. Additional details regarding the status of the site and recent activities can be found on the Site Progress page.

Project Update

Impoundments 1 and 2

WH is working with the USEPA under an Administrative Order on Consent for remedial design and engineering and a Consent Decree for remedial action implementation for Operable Unit 8 (OU8), commonly referred to as Impoundments 1 and 2. Additional information about the remedy can be found on the OU8 Remedy page.

  • Remedy demonstration campaigns were successfully performed in 2020, 2021, 2022, and 2023 providing important information on the most effective processes and procedures. The information from these campaigns will be used to finalize the remedial design and move the project into the remedial action phase.
  • Additional flood protection and resiliency efforts were implemented in 2022 prior to continuation of material removal campaigns.
  • Additional removal campaigns will continue in 2024 as the project transitions from the remedial design phase to remedial action.

Site-wide Remedy

WH is working under a Consent Decree with the USEPA to implement the site-wide remedy designated by USEPA as Operable Unit 4 (OU4). Under this agreement, WH is implementing the remedy of site soils, site groundwater, and a majority of the remaining impoundments still requiring remediation. Additional information about the site-wide remedy can be found on the Site-Wide Remedy page.

  • The on-site groundwater control, extraction, treatment, and reinjection system is complete and the system is has been fully operational since 2019. Visit the Site-wide Remedy page for additional information and photos of the groundwater treatment system.
  • WH has completed remediation activities in the northeastern corner of the property adjacent to the Bridgewater Train Station. Following remediation of this area, Somerset County constructed a new ADA compliant accessible pedestrian walkway and other improvements to the Bridgewater Train Station facility.
  • Additional areas of the site will be remediated in a phased approach over the next several years.
