GBU-28 The GBU-28 is a 5,000-pound (2,268 kg) laser-guided "bunker busting" bomb produced originally by the Watervliet Arsenal, Watervliet, New York. It was designed, manufactured, and deployed in less than three weeks due to an urgent need during Operation Desert Storm to penetrate hardened Iraqi command centers located deep underground. Only two of the weapons were dropped in Desert Storm, both by F-111Fs. One GBU-28 was dropped during Operation Iraqi Freedom.
Bowers Landfill Bowers Landfill, also known as Island Road Landfill, is a former privately owned landfill site covering 12 acres near Circleville, Ohio, on the Scioto River floodplain. The site operated between 1958 and 1968. Initially only domestic refuse was accepted, but from 1963 the site began accepting chemical waste from DuPont and PPG Industries. Waste was either dumped on the ground and covered with a layer of soil, or incinerated in the open air. Analysis of surface water undertaken by the United States Environmental Protection Agency in 1980 revealed the presence of contaminants and in 1983 the site was added to the National Priorities List (NPL) of hazardous waste sites eligible for long-term remedial action (cleanup) financed under the federal Superfund program. The cleanup was completed in 1993, and the site was removed from the NPL in 1997, but remains subject to review at 5-year intervals.
