The Michigan Department of Environmental Quality (MDEQ) is deploying drones to fly over Lake Margrethe to search for cold water springs that could be carrying PFAS contamination into the lake near Camp Grayling.  The MDEQ believes this is the first-ever usage of drones to search for PFAS contamination.

Explaining the GSI Pathway

 Explaining the GSI Pathway

Because of Michigan’s complex geology, the groundwater-surface water interface (GSI) plays an important role in the state’s environmental cleanup program. Last month, we shared with you information about recent updates made by the MDEQ to the Generic Cleanup Criteria Tables.  But what exactly is a GSI Pathway and how is GSI Pathway relevancy determined?
