On March 9, 1996, at the Rumpke sanitary landfill near Cincinnati, a precariously overbuilt waste slope collapsed and more than 20 acres of waste slammed into an adjacent excavation site. The failure, involving roughly 1.5 million cu yd of solid waste, was the single largest slope failure at a U.S. municipal solid waste landfill. The incident demonstrates the importance of stability when operating and expanding grandfathered landfill slopes. An investigation shows that remedial measures can prevent waste slides at similar landfills.
