Remedial Investigation/ Engineering Feasibility Study

MD&E is managing a multi-task study of the distribution of heavy metals and synthetic organic compounds in soil and groundwater reportedly associated with leachate from a 50-acre closed landfill. The subject landfill contains coal combustion by-products (CCBs), including fly ash, bottom ash and boiler slag from electric power generation facilities in central Michigan. Approximately 450,000 tons of CCBs were placed in the landfill. The objectives of the study are to: refine the current understanding of the waste characteristics and associated environmental impacts; facilitate an accurate assessment of risks posed by the facility to public health or the environment; and develop strategies to mitigate these risks, consistent with applicable federal and Michigan laws and regulations. The project also includes evaluation of conditions associated with munitions manufacturing performed on the site during the World War II era.
