Superfund Site Profile
The Dwyer Property Groundwater Plume site is located north of the intersection of Maryland Route 545 (Blue Ball Road) and Maryland Route 279 (Elkton Road), in Elkton, Cecil County, Maryland. The site is located in the area of former explosives manufacturing facilities known as Triumph Explosives and Aerial Products. This company manufactured products for the military. It has been inactive since 1972, and is currently abandoned and overgrown. The site consists of a two distinct groundwater plumes contaminated with volatile organic compounds (VOCs). A specific source of the VOCs in the northern plume has been identified on the property; however, a specific source for the southwestern plume has not been identified. The VOC plumes were initially identified by the Maryland Department of the Environment (MDE). MDE has performed a number of investigations at the site to try to determine the potential sources and extent of the plume.
