Recent examples of projects completed:

Assessment, remediation and permitting support for the reuse of an industrial property in Salem, MA for a 120 unit residential apartment complex. Five Underground Storage Tanks (USTs) were removed from a six acre industrial site that supported a fleet of delivery trucks. Two of the USTs leaked, requiring soil removal oversight and the implementation of a groundwater pump and treat system. The vehicle maintenance area required both soil removal and groundwater treatment. Additionally, two limited removal actions were required for minor releases. Altogether, nearly 1500 tons of soil were recycled and three Class A-2 Response Action Outcomes (RAOs) were achieved under Massachusetts General Law Chapter 21E and the Massachusetts Contingency Plan (MCP), 310 CMR 40.0000.

Assessment, permitting, design and construction management of the municipal landfill closure for the Town of Aquinnah, MA on the island of Martha's Vineyard. The project was completed in time and under budget with an aggressive schedule imposed by the Town and the Massachusetts Department of Environmental Protection (DEP). The project was completed in close cooperation with the Lawrence Lynch Corporation of Falmouth, MA.

Assessment and risk characterization of a former gasoline station in Peabody, MA. The site was closed with a Class A-2 RAO despite elevated levels of petroleum constituents in the groundwater. A modified Method 2 risk assessment under the MCP comprehensively identified all risks in the surrounding area to establish specific pathways and receptors that may be impacted. The site has been brought back to beneficial use without the need for an Activity and Use Limitation (AUL).
Permitting and design assistance of a new shellfish hatchery for the Wampanoag Tribe of Gay Head (Aquinnah) in Aquinnah, MA. The project proposes to raise scallop, quahaug and oyster seed for stocking coastal ponds on the Vineyard and the surrounding region. The permitting involves coordination of approvals through the Massachusetts Environmental Policy Act (MEPA) Unit, Massachusetts Coastal Zone Management (CZM), MA DEP, Massachusetts Division of Marine Fisheries (DMF), U.S. Army Corps of Engineers and the U.S. Environmental Protection Agency (EPA).
Engineering and permitting support for an 18 hole municipal golf course for the City of Peabody, MA: We have recently completed work to support the opening of a new municipal golf course located within 400 acres of open space in the cities of Peabody and Salem. The project was led by the golf course architects Cornish, Silva & Mungeam of Uxbridge, MA with technical support being provided by Decoulos & Company, Sasaki Associates of Watertown, MA and GeoHydroCycle of Newton, MA. The City of Peabody received a $500,000 grant from the MA Division of Conservation Services and is reusing industrial land owned by the Eastman Gelatine Corporation (a division of the Eastman Kodak Company). The project sought to preserve as much undisturbed land as possible, protect abutting public surface drinking water supplies and reuse brownfield land as part of a comprehensive passive recreational use for the area.

Project Review for the Conservation Commission in the Town of Saugus, MA: Reviewed the stormwater collection system design and hydraulic discharge from a proposed 39-lot subdivision. Coordinated neighborhood concerns of project impact with the Conservation Commission to control down-gradient project impacts.
Assessment and closure analysis of a former landfill in Arlington, Massachusetts. Coordinated geophysical investigations, subsurface investigations, mapping and closure study report for the law firm McGregor & Shea of Boston, Massachusetts.
Subdivision design and permitting for a five lot project in Marblehead, MA. The project required sensitive layout design and wetlands permitting in a well established neighborhood abutting conservation lands. Coordinated review through the engineering department, planning board and conservation commission.
Removal management of six USTs from a former estate in Canton, Massachusetts. Final report detailing activities prepared for the Massachusetts Audubon Society. The site was fully restored and a Response Action Outcome Statement was issued to the DEP.
Petroleum remediation of soil and groundwater at a residence abutting Radcliffe College in Cambridge, MA: 65 cubic yards of contaminated soil were recycled and a pump-and-treat groundwater-remediation system was implemented. The site was fully restored and a Response Action Outcome Statement was issued within six months of notification to the DEP.
Full permitting, design and construction oversight of the main roadway into Wampanoag tribal lands. The 2,500 foot roadway required the filling and replication of 8,500 square feet of wetlands which was coordinated through local, state and federal agencies. Construction was supervised in coordination with the U.S. Department of the Interior, Bureau of Indian Affairs. The project was funded and reviewed through the Federal Highway Administration.
