Superfund Site: KENNECOTT (NORTH ZONE)
MAGNA, UT

Superfund Site Profile

A five-year review was completed on June 17, 2014 to evaluate whether the remedies selected in the Records of Decision (ROD) remain protective of human health and the environment. The five-year review concluded the remedies are not protective in the long term because operation and maintenance and institutional control issues need to be resolved.

SITE BACKGROUND

The Kennecott (North Zone) site is located in Magna in Salt Lake County, Utah. Since 1906, the site processed copper, lead, zinc, molybdenum, arsenic, gold and silver-bearing ores. The resulting wastes contain hazardous substances, including heavy metals. Soils and sludge are contaminated, as are surface and groundwater, which affect wetlands between the site and the shore of the Great Salt Lake. Cleanup is ongoing.
