McGee Construction performs site work at the future school in Monmouth on Wednesday. As RSU 2 builds a new middle-elementary school in Monmouth, it has had to work with the Maine DEP to remediate non-natural levels of arsenic that were found on the site and likely related to pesticides used on an apple orchard that used to be there. The contractors have buried the soil containing arsenic about 7.5 feet under what will eventually be an athletic field, and state environmental officials say that it should remain contained there.
