Which Superfund site is now part of the Arizona State University Polytechnic campus?
Williams Air Force Base Williams Air Force Base is a former United States Air Force (USAF) base, located in Maricopa County, Arizona east of Chandler, and about 30 mi southeast of Phoenix. The area has since been annexed by the city of Mesa. It is a designated Superfund site due to a number of soil and groundwater contaminants.
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.
