Stratford, Connecticut
The Raymark Industries, Inc. Superfund Site includes areas that have been contaminated as a result of manufacturing processes from the former Raymark Industries, Inc. facility. The former Raymark facility operated from 1919–1989. Known as Raybestos-Manhattan, Inc., Raymark manufactured gaskets, clutches, and heavy brake friction components for the automotive industry. Raymark generated wastes containing asbestos, lead, copper, PCBs, and a variety of solvents, adhesives, and resins as byproducts of its manufacturing operations.
Sevenson is self-performing the excavation of contaminated soils at residential and commercial properties. Crews excavated 103,811 CY from 30 properties. Excavations have taken place in parking lots; business and residential properties along an existing water line; along and beneath structural foundations; in Ferry Creek; in a wetland area; and in a public park. Raymark waste soils were placed and compacted in an in-town consolidation area (OU4) for a low-permeability landfill cap of the former Raybestos Memorial Ballpark, and PHC-contaminated waste is sent to off-site facilities (10,135 tons). Sevenson completed the closure of the 11-acre low-permeability landfill capping system at OU4. ISS of 35,000 CY was utilized to treat material unsuitable for compaction with Portland cement to stabilize the material to the proper strength to meet specifications for cap construction. Additional scope of work included the installation of an 1,800 LF stormwater conveyance system and the excavation of 12,706 CY of Raymark contaminated sediment from a Ferry Creek, where crews utilized a 24-in. HDPE bypass pipe to excavate the creek in the dry. Sevenson received the Battle of Bunker Hill Certificate in May 2024 on behalf of USACE New England for successful completion of 30 properties within the Town of Stratford.
