Disposal— as defined by CERCLA and interpreted by EPA regulations, the discharge, deposit, injection, dumping, spilling, leaking, or placing of any solid waste or hazardous waste into or on any land or water so that such solid waste or hazardous waste or any constituent thereof may enter the environment or be emitted into the air or discharged into any waters, including ground waters. By judicial construction, the term also may include hazardous substances in repose in the environment, with the result that hazardous substances that have migrated to a site from an off-site source may nonetheless be considered to have been disposed at the site. See, for example, United States v. Waste Industries, 734 F.2d 159 (4^th Cir. 1984). This construction is not universally accepted. See, for example, United States v. Petersen Sand and Gravel, Inc., 806 F. Supp. 1346 (D.Ill. 1992). Source: (ASTM, 2004).
