The Eureka Mills Superfund Site is located in the East Tintic
Mountains approximately 80 miles southwest of Salt Lake City in
Juab County, Utah. The city of Eureka is part of Utah's historic
Tintic Mining District. Eureka was founded in 1870 upon the
discovery of a high-grade mineralized outcrop containing silver
and lead, as well as other minerals including gold, copper and
arsenic. The former mining sites are along the southern and
western boundary of Eureka City, and many are next to
residential areas. The mining and milling activities that took
place in the area between 1870 and 1965 left high levels of
heavy metals in the soil. Including elevated levels of antimony,
arsenic, cadmium, iron, lead, manganese, mercury, thallium,
vanadium, and zinc were also discovered. Public health interest
in the Eureka site began in July 2000, when elevated metal
levels were found in residential soil by the Utah Departmetn of
Environmental Quality (UDEQ). Cleanup began in 2001, and the
site was placed on the Superfund Nat
