Saw a tanker truck and people treating the VOC contamination at the Medfield State Hospital during my morning run. The man I queried said it would take about two weeks.
They get rid of the VOC by pumping a chemical into the ground to react with the VOC and render it inert. I am told that this is routine and will work well.
Once this is finished the only remaining clean up at the MSH will be the mediated fix to the C&D area, which should also be accomplished this year.
It is good that Medfield will be offered the opportunity to buy a basically clean site.
