Greetings!

Stone Environmental is excited to share updates on our recent work and previews of forthcoming projects.
SERVICE SPOTLIGHT: Indoor Air Quality Testing
Stone Senior Geologist Lee Rosberg demonstrates air sampling equipment.
All sites enrolled in Vermont's environmental liability limitation program (BRELLA) with buildings constructed before 1980 are required to complete air sampling for PCBs. These investigations can identify building materials containing PCBs now regulated by the Vermont Department of Environmental Conservation.
SERVICE SPOTLIGHT: Agency of Commerce and Community Development Funding
The new City Market Co-Op in Burlington, VT, following remedial planning and construction.
Stone continues to provide expertise and guidance for cleaning up and redeveloping underused or abandoned properties. Stone collaborates with the Vermont Agency of Commerce and Community Development's Brownfields Revitalization Fund. The Fund saw its largest investment last year, when Act 74 deployed $25 million in funding to characterize and cleanup brownfield sites across the state.
SERVICE SPOTLIGHT: Testing New Tools For PCB Extraction
PCB extraction in concrete slabs currently involves cutting and removing contaminated materials. Read a description of how Stone assessed the degree and extent of PCB contamination at a 20,000 square-foot building in Springfield, Vermont.
Stone will conduct a pilot test to evaluate the efficacy of removing PCBs from the concrete slab of a former manufacturing facility in Springfield, Vermont using the solvent extractant, CAPSUR®. This aqueous-based solvent system is developed for the extraction of PCBs in solid surfaces including wood, metal, asphalt, and concrete. If successful, this new method may drastically reduce remediation costs compared to demolishing and disposing building material.
UPCOMING EVENTS: The Science of PFAS, New England Brownfields Summits
The former Blodgett Oven Factory on the shore of Lake Champlain now the home of a mixed use development and business incubation space. Learn more about Stone's work on this site here.
Stone is proud to sponsor and participate in two upcoming events this spring.

Environmental Modeler Marco Propato will share insights into the use of agricultural chemical fate and transport models to determine biosolids PFAS screening level concentrations required for groundwater protection this week at the Northeast Conference on the Science of PFAS: Public Health & the Environment in Marlborough, Mass., April 5-6.

The Revitalizing New England: Brownfields Summit 2022, May 18-19 in Devens, Mass regional Summit promises opportunities to exchange information and strategies for cleaning up and redeveloping Brownfields. Senior Geologist Lee Rosberg will present lessons from our work cleaning up the former Blodgett Oven Factory in Burlington, Vermont.
