An underground storage tank was on the site. Allied Paint Manufacturing Co., Inc., acquired the site in the mid-1970s. In 1979, while Allied owned the site, a fire destroyed a building on the site. Subsequently, Allied removed the underground tank. Keystone Hydraulics, a hydraulic equipment repair facility, has owned the site since 1979 and also stored construction equipment at the site.
Contamination decreases with distance from the site.
An estimated 101,000 people obtain drinking water from public and private wells within 3 miles of the site. An unnamed tributary to Towamencin Creek is about 5,000 feet from the site. EPA is evaluating additional sources of contamination. The description may change as additional information is gathered on the sources and extent of contamination.
