Dioxins and furans have been identified at locations throughout the Tittabawassee River and floodplain in Michigan, extending from the Dow Chemical Company facilities in Midland to the Tittabawassee’s confluence with the Saginaw River in Saginaw. LimnoTech has been a consistent and critical member of the consultant teams, assisting Dow in characterizing the river, planning and conducting remedial investigations, and designing remediation and restoration activities.
The Tittabawassee River is the subject of an ongoing remedial investigation. At the beginning of the project, little was known about the way the Tittabawassee River moves water and sediments, and how hydrophobic contaminants move through the system. As part of the remedial investigation, the Dow Chemical Company is addressing questions about historical migration of contaminants, as well and present-day stability and potential for remedy effectiveness.
LimnoTech is performing a variety of studies to characterize the Tittabawassee River and floodplain, and the movement of sediment and contaminants within the system. These activities include very high resolution, multi-dimensional hydrodynamic and sediment transport modeling of 26 miles of the river, as well as bank, floodplain, flow, and solids transport studies.
LimnoTech’s activities are providing a thorough understanding of how the river functions, which will allow Dow to develop an economical and effective remedy.
