News	We'll be at the Fall Northeast Arc Users Group Conference Next Week! We're thrilled to participate in the Fall Northeast Arc Users Group Conference (NEARC) in New Haven, CT, next week! As proud sponsors of this event, we can't wait to support and connect with the vibrant GIS community.
News	News and Updates from Our Environmental Assessment and Remediation Team Learn more about the latest additions to our team, new staff credentials, funding updates for the brownfields program in Vermont, and recent project developments.
News	Join Us at the American Chemical Society's Fall 2023 Meeting We're proud to sponsor the American Chemical Society's (ACS) Fall 2023 Meeting, August 13-17, 2023. We hope you will join us in San Francisco, California, where we will share insights from our recent work.
News	Join Us in Welcoming Our New Senior Ecotoxicologists, Dwayne Moore and Scott Teed We're thrilled to share that Dwayne Moore, Ph.D. and Scott Teed have joined Stone as Senior Ecotoxicologists. They have been trusted partners for over a decade on ecological risk and endangered species assessments and are now permanent members of our team.
Case Study pdf (198 KB)	Johnsons Mill Dam Removal and Long-Term Monitoring Stone offered technical expertise and project management support from the preliminary design stage to the construction phases of removing the Johnsons Mill Dam in Bakersfield, Vermont. Currently, Stone is conducting a five-year monitoring program post-dam removal to evaluate the effects of the removal on stream habitat.
News	News and Updates from Stone's Geospatial and Data Solutions Team Our Geospatial and Data Solutions team participated in the Esri User Conference, achieved the Esri System Ready Specialty designation, share progress on the new New York Geographic Information Gateway, and celebrated some recent team promotions.
Case Study pdf (333 KB)	Per- and Polyfluoroalkyl Substances Investigation and Drinking Water Sampling and Reporting at Southern Vermont Regional Airport In 2018, the Vermont Department of Environmental Conservation (VT DEC) and the Vermont Agency of Transportation (VTrans) evaluated the Southern Vermont Regional Airport (SVRA) in North Clarendon, Vermont for potential impacts related to the use of aqueous film-forming foam (AFFF) in firefighting apparatus during firefighting training and fire response activities. A phased sampling of bedrock groundwater monitoring wells revealed that groundwater in bedrock was impacted by common constituents of AFFF known as per- and polyfluoroalkyl substances (PFAS).
Case Study pdf (210 KB)	Westford Community Wastewater Disposal Project Stone is advancing or supporting several village-scale, soil-based wastewater infrastructure projects that allow modest growth and redevelopment in unsewered villages and designated growth centers. One project advancing to final design after over a decade of careful planning and collaboration is in Westford, Vermont. In 2006-2007, Stone worked with an engineering partner to conduct a wastewater feasibility study for Westford’s Town Center zoning district. Although this area is the Town’s designated growth center, clay-rich soils and shallow bedrock make increasing development density a challenge even on existing relatively large lots.
Case Study pdf (690 KB)	Deer Brook Gully Restoration, Georgia, Vermont The Deer Brook watershed includes approximately 8.4 square miles in the towns of Georgia and Fairfax. Deer Brook flows into Arrowhead Mountain Lake, and ultimately into Lake Champlain and is considered to be impaired by sediment, from its mouth 2.5 miles upstream. Since the construction of I-89 and related U.S. Route 7 improvements in the 1970s, and subsequent addition of homes and businesses near the intersection with Route 104A, contributed to this impairment, as storm flows discharge at the head of a gully first assessed and documented by ESPC and Stone in a 2007 report to the Northwest Regional Planning Commission (NRPC).
