The site’s long-term remedy, selected in 1997, included monitored natural attenuation (MNA) for both the western and eastern plumes of contaminated groundwater, with soil vapor extraction (SVE) added for the eastern plume. The SVE system has been operating since 1999. VOC concentrations in the soils have decreased 98 percent.

Bendix Corp Allied Automotive is a federal Superfund site in Michigan.
