EPA FACILITY ID: MID980901946; prepared by: Michigan Department of Community Health under a cooperative agreement with the U.S. Department of Health and Human Services Agency for Toxic Substances and Disease Registry.

The Michigan Department of Environmental Quality (MDEQ) and the Western Upper Peninsula Health Department (WUPHD) requested an updated public health assessment of the Torch Lake Superfund site and vicinity in Houghton and Keweenaw Counties in Michigan. The Torch Lake Superfund site is complex, with three Operable Units (OUs) covering hundreds of acres within Houghton County in the Keweenaw Peninsula of Michigan’s Upper Peninsula, dealing primarily with contamination left behind by copper mining, processing, and reclamation activities. This document addresses inhalation exposure to stampsands from excavation work, recreation, or when road-applied stampsands are resuspended in air.
