The Bautsch-Gray Mine site is located in Jo Daviess County, Illinois. The site included an operational lead and zinc mine. Since it closed in 1975, tailings from the mine property have continued to erode and move toward residential properties, wetlands and fisheries. Erosion of these materials contaminated soil, groundwater and surface water. Waste piles contain elevated levels of lead, arsenic and other heavy metals, and soil samples from around the site and a nearby residential property contain elevated levels of lead. EPA is currently investigating the extent of contamination at the site.
