Superfund Site: INTERNATIONAL SMELTING AND REFINING
Superfund Site Profile
The International Smelting and Refining (IS&R) site is located about two miles northeast of Tooele, Utah, on the west flank of the Oquirrh Mountains near the mouth of Pine Canyon. The site consists of the Pine Canyon Conservation Area, the Pine Canyon/Lincoln Township Area and the Tooele Valley Railroad. From 1910 until 1972, copper, lead and zinc smelting and refining activities caused contamination at the smelter property and adjacent lands. Site investigations found heavy metal contamination in soils, tailings and slag. Following cleanup, EPA took the site off the Superfund program’s National Priorities List (NPL) in October 2011.
