Superfund Site: JACOBS SMELTER

Superfund Site Profile

A Record of Decision (ROD) that documents the cleanup decision for Operable Unit 2 (OU2) was signed in September 2016. Remedial design and construction are slated for 2017, but are dependent on federal funding.


The Jacobs Smelter site is located in the Rush Valley, Tooele County, Utah near the town of Stockton and about five miles south of Tooele, Utah. The site covers about eight square miles and includes the town of Stockton. The risks posed by the site derive from smelting and mining activity, which occurred primarily in the 1860s and 1870s. Wastes in the form of heavy metal contaminated soil, mill tailings, and smelter wastes exist at several locations within the site boundaries. The primary contaminants are lead and arsenic.

Cleanup is complete for several areas of the site. Investigation and evaluation of cleanup options in the remaining areas is ongoing.
