Perry Creek – Hoskins Manufacturing – Mio, MI
September 2008 - For the latest information on the Hoskins clean-up, please go to the DEQ website: http://www.stsextranet.com/HPS/default.aspx
February 2008 - The contaminates at Hoskin Manufacturing are creeping toward Perry Creek at the rate of approximately 200 ft/month, and are now about 2 miles from the creek. PCE moves faster than the hexavalent chromium. The concentration in Perry Creek is presently 8 ppm, with a toxic level being 11 ppm.
September 2007 - Perry Creek - Late September Anglers had a meeting with DEQ Remediation Division. Hoskins Manufacturing, Mio plant, 3 miles NE of Mio, manufactured thermoelectric nickel and chromium alloys in the form of wire, strip and ribbon. They operated from the late 1960's to 2001. Poor waste handling and chemical storage practices have caused serious groundwater contamination. The primary contaminants in the groundwater are PCE, hexavalent chromium and chlorides. The plume travels SE to Perry Creek and is approximately one half mile long. A portion of the groundwater contamination plume discharges to Perry Creek and a portion goes beneath and beyond (east of) Perry Creek, and is venting directly into the creek. PCE and chromium have been detected in the surface water samples in Perry Creek as far as 700 feet south of where the groundwater contamination enters the creek. The United States Environmental Protection Agency (USEPA) has hired a service contractor to remove thousands of tons of contaminated soils. The buildings are slated for demolition late in the fall of 2007 to access more contaminated source soils. Additional testing and groundwater investigations are underway to determine the extent of contamination to soil and aquatic organisms in Perry Creek. The task at hand is difficult. It is the integrated technology to remediate a "fruit salad" of contaminants at the same time. Both groundwater, and surface water systems are an issue in this case. We'll monitor the situation and possibly offer private sector remediation consultants to help with the design of remediation alternatives. The Michigan Council of Trout Unlimited has offered to show their support for our resource protection issues by committing $5,000 toward our efforts.
