Two Unexploded Munitions Scheduled for Open Detonation
Camp Edwards, Mass. — Two unexploded munitions found in the Central Impact Area at Camp Edwards on the Massachusetts Military Reservation (MMR) will be destroyed in open or blow-in-place detonations between 8 a.m. and 5 p.m. on Thursday, April 25.
The items include an 81-millimeter mortar and a 75-millimeter projectile, which were found by Groundwater Study Program contractors while clearing drilling sites for two new monitoring wells near the southeast corner of the impact area. The wells are being installed as part of the program's investigation into groundwater contamination resulting from historic training activities.
The detonations will be in the 2,200-acre impact area at the center of Camp Edwards and will not affect the Sandwich neighborhood buffer zone. There is no risk to residents of the nearby area.
Massachusetts Army National Guard contractors have determined that the munitions are unsafe to move and represent an immediate explosive hazard to workers in the area. This requires the items be blown in place.
Following the detonation the soil in the area will be tested for residual explosive compounds. If any contamination is found, the soil will be scheduled for removal and disposal in accordance with applicable regulations.
The Groundwater Study Program, led by the National Guard Bureau, has been working on an investigation and cleanup of the upper 15,000 acres at Camp Edwards since 1997. The Environmental Protection Agency and the Massachusetts Department of Environmental Protection oversee the program.
