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, has implemented 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.


On March 9, 2021, the CTDEEP issued a Stewardship Permit for the Pharmacia & Upjohn Company LLC Site. With remediation construction activities complete, Pharmacia and Upjohn has fulfilled its obligations with the USEPA, with the exception of some administrative filings. The CTDEEP Stewardship Permit covers ongoing obligations, including operation of the onsite groundwater extraction and treatment system, which will operate for the coming years.
