Penobscot River - Phase III Engineering Study - Community Involvement Program (Belfast)

The Penobscot River and Estuary are contaminated with mercury as a result of historical releases from sources including a former chlor-alkali plant in Orrington, Maine (often referred to as the HoltraChem Plant). By order of the United States District Court for the District of Maine, a team of engineers and scientists are evaluating how best to reduce the levels of mercury in the Penobscot River system to reduce threats to human health and the environment. This evaluation is called the Phase III Engineering Study.

As part of this work, the Study Team is developing a Community Involvement Program to inform and involve interested stakeholders about the investigation and potential remedial activities. Input from potentially interested stakeholders provide valuable insights on how to best inform and involve the community about the investigation and evaluation of potential remedial activities. The Study Team would like to seek input through a short online survey: The survey should take approximately 5 minutes to complete.

As a first step in sharing information, the Study Team has developed a website of relevant information. The website can be viewed here: . We welcome your feedback on the website.

The Study Team’s Community Involvement Program Lead, Mary Kelly, welcomes your input. Mary will be conducting meetings with interested stakeholders in the Study Area in mid- to late July 2017. If you would like to schedule a time to discuss the Community Involvement Program with Mary please contact her. Should you have questions or wish to speak to Mary please contact by email ( or phone (207-828-2604).
