BOSTON, Ma. — Geosyntec Consultants was recently awarded a contract to prepare the remedial design for the Sutton Brook Landfill Superfund Site in Tewksbury, Mass.
Also known as Rocco's Landfill, the Sutton Brook Landfill was added to the Federal Superfund List in 2001. The site is located off South Street in the eastern part of Tewksbury, where waste disposal activities can be traced back to the mid-1950s. The site comprises several areas of concern, including a 40-acre landfill, divided into two separate lobes by Sutton Brook (a tributary of the Shawsheen River) and associated wetlands, contaminated soils associated with a former drum disposal area, contaminated soils in a former Garage and Storage Area, contaminated sediments in Sutton Brook between the landfill lobes, and a down-gradient groundwater area. Geosyntec will be designing aspects of the closure and treatment systems, including: excavation and consolidation of contaminated soils and sediments; low-permeability caps for both lobes of the landfill; a barrier system to separate impacted groundwater from water in Sutton Brook; and groundwater treatment systems that will include a monitored natural attenuation component.
Scott Luettich, PE, Geosyntec's project director for the Sutton Brook work, said, "This is a very important win for Geosyntec, particularly for our local Acton, Massachusetts, office. This project spans many of our areas of expertise, including solid waste and geotechnical engineering, hydrogeology and groundwater remediation, and natural resource management. We are very proud to have been selected from amongst a group of qualified competitors, and are looking forward to working with our clients and the regulatory agencies on this project to clean up the Sutton Brook Site."
