The Public Health Assessment about the inhalation of airborne stamp sands in the Torch Lake Superfund site and the surrounding area in Houghton and Keweenaw Counties, evaluated concentrations of metals in airborne stamp sands. MDCH estimated the air concentrations using site-specific data, when available, and relying on regulatory guidance. Exposures that may occur during excavating or riding off-road vehicles at the Gay tailings pile along Lake Superior are not expected to cause harm. MDCH needs more information to determine the public health implications of exposure during street-sweeping activities in Calumet, when stamp sands that were applied to the roads in the winter become airborne. The discussion in this Public Health Assessment can guide other agencies in future evaluations of these and other stamp-sand piles.
During the June 20, 2012, multi-agency open house in Lake Linden, Sharon Baker, right, Michigan Department of Environmental Quality Area of Concern coordinator, discusses information about the Torch Lake Superfund site with Sarah Green, Michigan Tech professor and chair of the Department of Chemistry.
The Public Health Assessment about recreational use at beach areas at Lake Linden and along Torch Lake in Houghton County looked at potential chemical exposure from recreationally used areas around Torch Lake, Boston Pond, and Calumet Lake. Even though contaminated soil and sediment have been removed from several areas, additional sampling is needed to determine if the remaining chemicals present may harm people's health. Fish from Torch Lake, Boston Pond, and Calumet Lake are under waterbody-specific and statewide fish-eating guidelines. Visit www.michigan.gov/eatsafefish for more information.
MDCH also invites the public to provide comments on the Public Health Assessments. The assessments are online at www.michigan.gov/mdch-toxics under "Health Assessments and Related Documents." Copies also are available at the Lake Linden-Hubbell Public School Library, and the Portage Lake District Library located at 58 Huron St. in Houghton. Comments must be received by June 24. Responses to all comments will be provided in the final version of the assessments.
The department's Division of Environmental Health conducted the Public Health Assessments under a cooperative agreement with the federal Agency for Toxic Substances and Disease Registry (ATSDR). Information concerning the human health effects of exposure to environmental contaminants can be found on the ATSDR web page at http://www.atsdr.cdc.gov/toxfaqs/index.asp.
