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.

COVID-19 Update

Work continues at the Site; however, operations have been modified due to the uncertainty associated with the COVID-19 virus. The Site is closed to all visitors and access is limited to critical personnel. Site security measures and operation of the onsite groundwater extraction and treatment system continue. COVID-19 safety protocols have been implemented and site contractors have taken extra precautions such as adding hand washing stations, use of appropriate personal protective equipment, and maintaining social distancing whenever possible. The technical staff continues to work on remediation designs and other tasks remotely and will work diligently to keep the overall project moving forward despite the challenging circumstances. 

Project Update

Impoundments 1 and 2

On September 30, 2019, USEPA and WH executed an Administrative Order on Consent that allows WH to move forward with design and engineering for the remediation of Operable Unit 8 (OU8), commonly referred to as Impoundments 1 and 2. A Consent Decree for Remedial Action Implementation was finalized with the effective date being November 15, 2021. Additional information about the remedy, described in the Record of Decision issued by USEPA on September 25, 2018, can be found on the OU8 Remedy page.

  • A scaled-up remedy demonstration campaign was successfully performed in 2021, providing important information on the process and procedures to be incorporated into the remedial design.
  • Additional flood protection and resiliency efforts are planned for 2022, prior to continuation of material removal campaigns. The construction of expanded flood control berms and elevated work platforms will begin in late April 2022 and take approximately six months to complete.

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 moving forward with the remedy of site soils, site groundwater, and a majority of the remaining impoundments still requiring remediation, as described in the Record of Decision issued by USEPA on September 27, 2012.

  • The WH team has invested significant resources in the engineering and design of this remediation program. Construction of the groundwater control, extraction, treatment, and reinjection system is complete and the system is fully operational. Visit the Site-wide Remedy page for additional information and photos of the groundwater treatment system.

Impoundment 8 Facility

The Impoundment 8 Facility located on Polhemus Lane in Bridgewater, was designed to receive stabilized/treated waste exclusively from other areas of the Site as part of a multi-phase remediation program. In 2018, EPA issued the final CERCLA Record of Decision choosing a remedy to address impacted soil, groundwater and surface impoundments at the Site. Based upon EPA’s selected remedies, the Impoundment 8 Facility will not be necessary to manage more waste/material. Therefore, WH is implementing a final closure and post-closure care plan for the Impoundment 8 Facility. For additional information, visit the Impoundment 8 Facility webpage.

  • WH is implementing a NJDEP-approved Remedial Action Work Plan which calls for a portion of the material within the Impoundment to be redistributed and regraded to lower the profile, improve aesthetics and allow for stormwater management. A final impermeable cover system has been put in place, and the area graded for stormwater management. A seed mix cover was added to the area in 2022 to provide a final vegetated cover.
