The 2.2-acre Utah Power & Light/American Barrel Co. site is located in Salt Lake City, Utah. Barrel storage, wood-treating and coal gasification operations took place on site from 1870 to 1987. The wood-treating and coal gasification operations produced byproducts such as tar, sludge, ash and liquid wastes. Site activities and waste disposal practices contaminated soil and groundwater with hazardous chemicals. Following cleanup, operation and maintenance activities are ongoing.
