EPA added the site to the National Priorities List (NPL) in 2003. Investigations by EPA in 1992 and by the Utah Department of Environmental Quality (UDEQ) in 1994 found high levels of arsenic and lead in soil at both smelter locations. In 1991, the discovery of ladle casts in Little Cottonwood Creek near the Flagstaff Smelter prompted a study of smelter sites in the Salt Lake Valley. The Davenport, McKay and Flagstaff smelters operated throughout the 1800s. The site is in a residential and commercial area at the mouth of Little Cottonwood Canyon. The Davenport and Flagstaff Smelters Superfund site is located near Sandy, Utah, about 15 miles from Salt Lake City. These businesses employed 47 people and generated an estimated $2,952,704 in annual sales revenue. Interstate 15 and rail lines also cross the site.Īs of October 2022, EPA had data on 4 on-site businesses. There are continued industrial, agricultural and residential land uses in the area impacted by groundwater contamination. BFC remains active at the site and leases parts of its property to other commercial businesses. The Utah Transit Authority paved part of the Hatchco property to serve as a vehicle parking lot for the Utah Commuter Rail System. Construction of the water treatment system finished in 2011. Cleanup included use of barriers, a water treatment system and long-term monitoring. EPA added the site to the National Priorities List (NPL) in 2001.
PCE is a solvent used by dry cleaners in the cleaning process and TCE is used as a solvent to remove grease from metal parts. The main contaminant at the BFC property was tetrachloroethylene (PCE) and at the Hatchco property was trichloroethylene (TCE). Over time, spills and leaks from operations and holding tanks contaminated soil and groundwater.
From 1936 to 1996, several businesses operated on site, including a petroleum facility, a dry cleaner and a trucking business. It includes two properties – the 50-acre Hatchco property and the 400-acre Bountiful Family Cleaners (BFC) property. The 450-acre Bountiful/Woods Cross 5th South PCE Plume Superfund site is in Bountiful, Utah.
