This site serves as a source of news and information for the residents of North Haven and the surrounding communities regarding corrective measures at the Pharmacia & Upjohn Company LLC Site.


Under the guidance of the Connecticut Department of Energy and Environmental Protection (CTDEEP) and the U.S. Environmental Protection Agency (USEPA), Pfizer, on behalf of its subsidiary Pharmacia & Upjohn Company LLC, is working to implement corrective measures that 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 Quinnipiac River regional ecosystem;
  4. And to position the property as an asset to North Haven and the Quinnipiac River region.


The USEPA approved the final remedy for the site on September 10, 2010. On March 31, 2011, USEPA and Pharmacia & Upjohn Company LLC entered into an updated Administrative Order on Consent to facilitate site remediation and return the property to productive use.

Engineering, design and construction for the approximately $150 million cleanup project is currently underway.

On October 6, 2014, Pfizer welcomed USEPA Region 1, CTDEEP, representatives of the Town of North Haven, and the Citizens' Advisory Panel to the site to commemorate the near completion of east side remediation activities and initiation of ecological restoration along the banks of the Quinnipiac River.
