After the EPA declared the Tintic Mining District to be on the NPL list, Atlantic Richfield retained Anderson Engineering.
Our Senior Construction Team prepared surveys of existing conditions, provided remedial designs for impacted areas, and offered technical support during construction. Designs included groundwater pumping systems, hydraulic structures, roads, covers, and more.
The 450-acre Eureka Mills site is part of Utah’s historic Tintic Mining District, located in the East Tintic Mountains about 80 miles southwest of Salt Lake City in Juab County, Utah.
Eureka was founded in 1870, following discovery of a high-grade mineralized outcrop containing silver and lead as well as other minerals, including gold, copper and arsenic. The area was extensively mined until 1958. Large waste rock piles and associated waste material resulting from mining operations were left primarily on the south side of the valley, immediately adjacent to residences and businesses. Transport along rail lines, milling operations and use of mine waste for urban construction spread mine waste throughout the town.
The site includes the residential and commercial parts of Eureka and some adjoining areas outside of the city limits. The State of Utah discovered contamination at the site during an inspection in July 2000. Following cleanup, operation and maintenance activities are ongoing.
