Redevelopment at the Site

The 16-acre A.I.W. Frank/Mid-County Mustang Superfund site is located in Exton, Pennsylvania. The site includes two properties: the 15-acre A.I.W. Frank property and the 1-acre Mid-County Mustang property. From 1962, manufacturing of Styrofoam cups and plates took place on the A.I.W. Frank property. After 20 years, property ownership changed and the manufacture of refrigerators, freezers and warming cabinets for the institutional food service industry occurred on site. Since the 1940s, auto repair facilities and body shops operated at the Mid-County Mustang property. Disposal of used of solvents and degreasers on both properties resulted in contamination of soil and groundwater. EPA placed the site on the Superfund program’s National Priorities List (NPL) in 1989. Cleanup activities included soil removal, demolition of a building damaged by fire, extraction and treatment of groundwater. EPA also connected nearby residents to the public water supply. Currently, grass and remaining concrete cover the vacant A.I.W. Frank property. An auto garage continues to operate on the Mid-County Mustang property. The Mid-County Mustang property also includes a parking lot and a small lawn area.

Activity and Use Limitations

At this site, activity and use limitations that EPA calls institutional controls are in place. Institutional controls play an important role in site remedies because they reduce exposure to contamination by limiting land or resource use. They also guide human behavior. For instance, zoning restrictions prevent land uses – such as residential uses – that are not consistent with the level of cleanup. For more background, see Institutional Controls.

Institutional controls are in place that currently prevent new residential wells from being installed in contaminant plume.
