Current Status

Site Remediation and Stewardship

On March 31, 2011, U.S. Environmental Protection Agency (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.

Significant resources were invested to upgrade the groundwater control, extraction, conveyance and treatment system and address soil and sediment impacts on the east and west side of the property. The USEPA deemed the remedy construction complete on September 30, 2019.

The Pharmacia & Upjohn Company LLC has completed its obligations under its Order with the USEPA, with the exception of some administrative reports and filings which will be completed by December 31, 2022.

On March 9, 2021, the Connecticut Department of Energy and Environmental Protection (CTDEEP) issued a Stewardship Permit for the Pharmacia & Upjohn Company, LLC Site. The CTDEEP Stewardship Permit covers ongoing obligations, including groundwater monitoring, maintenance of engineered controls, and operation of the onsite groundwater extraction and treatment system, which will operate for the coming years.

Property Reuse and Redevelopment

The site-wide remedy provides long-term protection to human health and the environment and returns the property to productive use.

Brick Yard Point Preserve

Approximately 57-acres of tidal marshes, fresh water wetlands and upland meadows have been restored on the eastern side of the property. A self-guided interpretive trail system, totaling nearly two miles in length, has been created along the banks of the Quinnipiac River. The preserve is open to the public on a limited basis by appointment April through October. For more information, visit

West-Side Redevelopment Area

Approximately 17 acres of land on the western side has been made available for future commercial or light industrial use. The Connecticut Department of Transportation has expressed interest in locating a passenger rail station on a portion of the western side. Redevelopment opportunities compatible with the site-wide remedy continue to be evaluated.
