This research discusses the results of a state-wide study conducted by The Michigan Department of Environment, Great Lakes, and Energy to assess the presence of PFAS in shallow soils of state-owned forested areas in Michigan utilizing a composite sampling method. One sample collected from each of Michigan’s 83 counties reveals the presence of PFAS in all but one sample, with total PFAS concentrations ranging from non-detect to 2.016 μg/kg (dry weight). PFOS is generally detected at the highest concentrations, ranging from non-detect to 0.88 μg/kg, followed by PFBA, with concentrations ranging from non-detect to 0.69 μg/kg, and PFOA, with concentrations …

Closure of hazardous waste sites can be aided through the use of a soil background survey for metals. Data for these studies come from either field sampling or publicly available environmental files. Previous studies were conducted in Michigan, known as the Michigan Background Soil Survey (MBSS). The current update is a refinement and improvement of the 2005 update. New data was collected from publicly available environmental files and other sources. Both the current update and the 2005 update differentiated data by soil type and glacial lobe. GIS analysis was used to observe spatial distribution of the data and to determine …
