Remedial Investigation / Feasibility Study

Over the years, the Army Corps of Engineers has conducted investigations to evaluate if any military-related materials remain at the site. A site inspection was completed in 2008 and concluded that a Remedial Investigation/Feasibility Study is necessary for the following project areas: North Pier, Dump Area, South Pier, Furnace Area, Weymouth Back River, and Burial Area. The North Pier and South Pier were 1.8-acre and 3.5-acre areas, respectfully, used for transportation of packaged ammunition. The Dump Area was a 1-acre dump area on a steep back on the edge of the Weymouth Back River, used for disposal of solid waste and potentially munitions related items. The Furnace Area was a 3-acre area used for disposal of unserviceable and unused munitions. The Weymouth Back River site encompasses is 227 acres in and around the Weymouth Back River (203 acres of water and 24 acres of land), used for transportation of packaged ammunition. The Burial Area is an 8.2-acre area that was used for the disposal of solid waste, to potentially include munitions related items.

The Remedial Investigation/Feasibility Study was conducted between 2018 and 2020; the purpose was to determine if any munitions related items or their residual by-products remain in the area from the military’s use of the property, and if so, in what amounts and in what location.

The fieldwork included searching for munitions related items and collecting environmental samples to test for metals and explosives. No munitions and explosives of concern were found during the field investigation (or field work). Environmental sampling concluded there were no human health or environmental concerns from munitions related items or their residual by-products remain in the area. The results will be summarized in a document called a Proposed Plan which will present the alternatives. The alternatives can range from no further action being necessary to educating the public about the site to conducting a removal action to search for and remove munitions. When the Proposed Plan is ready, the Corps will present it at a public meeting, and the public will have 30 days to review and submit comments on the plan.
