Superfund Site Profile
The 50-acre Crater Resources, Inc./Keystone Coke Co./Alan Wood Steel Co. site is located in Upper Merion Township, Pennsylvania. The site consists of four inactive quarries. Beginning in 1919, Alan Wood Steel Company disposed of wastes generated by its coking facility in Swedeland, Pennsylvania, in three of the quarries at the site. In 1977, Keystone Coke Company purchased Alan Wood Steel Company. The firm continued to dispose of wastes at the site until 1980, when all operations at the facility ceased. Site activities contaminated soil, sediment and groundwater with hazardous chemicals. Remedy construction is underway.
