The analysis yielded a total of 13 clusters, including: 3 clusters among the soils impacted by contamination present in the Tittabawassee River sediments, a cluster comprised mainly of samples collected within the depositional area of the Dow incinerator complex, a small cluster of samples with elevated 2,3,7,8-tetrachlorinated dibenzo-p-dioxin Dow Chemical wastewater characterization study: Tittabawassee River sediments and native fish. Letter from E.H. Blair, U.S. Area Research and Development, Midland, Michigan, to Document Control Officer, Chemical Information Division, EPA's review was conducted under the dioxin science plan announced by Administrator Lisa P. Jackson this past May. The University of Michigan Dioxin Exposure Study (UMDES) was conducted in response to community concerns that dioxin compounds from the Midland-based Dow Chemical Co. had contaminated the city and surrounding areas. A fish consumption patterns survey of people fishing in the Saginaw River, Saginaw The assessment of dioxin concentrations in the lower Tittabawassee River is to be This contamination characterization is required as part of Dow Chemical Additional characterization of the Tittabawassee River, Saginaw River and Dow discovered the latest hot spot during sampling done according to its own Sept. 14, 2007 work plan, which has not been approved by either EPA or MDEQ. As a result of EPA Superfund orders in June 2007, Dow is now wrapping up the cleanup of three dioxin hot spots in the Tittabawassee River and should be done by year's end. Michigan Dioxin Studies.
