In 2023, Stone was contracted by CDM Smith to serve as a local environmental firm and technical lead for the final investigation and remedial implementation phases of the cleanup project for the Commerce Street Superfund Site in Williston, Vermont. The site has been the subject of investigation since 1984 due to the discharge of rinse water and sludge wastes containing chlorinated solvents to an unlined lagoon.

Our team implemented a dynamic investigation strategy to not only develop a firm understanding of the plume makeup, but also ensure all aspects of the site’s environmental challenges were addressed. This has included collaboration with specialized ecological and surveying partners to support wetland delineation, ecological assessments, and geophysical survey as well as community engagement with the town of Williston, surrounding residents, and businesses.
