DCAMM carting away the MSH soils with VOC’s

Below is the DCAMM flyer from the fence at the Medfield State Hospital Overlook, retrieved during last evening’s walk. Currently there is a huge hole dug out at the site of the VOC (perc I think) plume (the formerly laundry building site) between the mural and the Overlook, and a huge pile of those soils in the adjoining field. This is the website DCAMM lists for more information.
