The explosions scattered thousands of shells and components over a wide area, more than in radius. Nearly a century later, unexploded ordnance from the facility was still being found in the surrounding area. On June 7, 2007, ordnance was discovered at Samsel Upper Elementary School while workers were grading an area for a playground. Explosive Ordnance Disposal specialists from the US Army were called in to remove the material. Previously, in 1994 and again in 1997, the discovery of shells near Sayreville's Dwight D. Eisenhower Elementary School spurred cleanup operations by the US Army Corps of Engineers, which collected and disposed of a combined total of 5,080 pieces of ordnance.
