Segment 1. Work in Segment 1 will be completed November 2013. Segment 1 is the 3-mile stretch of the Tittabawassee River next to the Dow Chemical Plant in Midland.
The Segment 1 cleanup removed and treated dense non-aqueous phase liquid (DNAPL). DNAPL is a highly contaminated oily liquid that’s heavier than water and does not dissolve. So far more than 4,000 gallons of DNAPL has been pumped from Segment 1 and sent to the Dow Chemical Co. incinerator.
A containment system was installed in three areas of Segment 1 to isolate contaminated sediment. After cleanup, the area will be monitored and cleanup systems will be operated and maintained.
Segment 2. The next stretch of the river to be cleaned up is Segment 2. Segment 2 is a four-mile stretch of the river below the Dow Chemical Co. Plant in Midland. Dioxin is the main contaminant . EPA proposed a cleanup plan with a combination of cleanup actions that will stabilize and clean up dioxin-contaminated sediment and riverbanks. Work in Segment 2 will start in spring 2014.

Off-site dioxin contamination from the Dow Chemical facility in Midland, Michigan extends over 50 miles downstream through the Tittabawassee and Saginaw Rivers and into Saginaw Bay, which is part of Lake Huron. EPA, working with the Michigan Department of Environmental Quality, is directing Dow’s investigation and cleanup of the river. The Tittabawassee River has been divided into seven segments ranging from three to five miles each. Work is being done in stages from upstream to downstream, segment-by-segment. Segment 1, a 3-mile stretch next to Dow’s Midland plant, is the most upstream segment. Cleanup of Segment 1 started in 2012 and is expected to be complete in 2013.
