Locating the source of PCBs then took considerable sleuthing and further testing. At Clarke, PCBs were found only in window caulking; mitigation was relatively simple to do: remove the caulk, encapsulate the surrounding building masonry, and recaulk windows with non-PCB material.
At Estabrook though, it was an entirely different matter.
Eventually, PCBs were found in all of the floor and ceiling mastic, as well as the window caulk, and in the mastic used to affix both interior and exterior decorative wall panels.
In January of 2012, Lexington voters approved a debt exclusion override to appropriate funds for extraordinary repairs to the Bridge and Bowman Elementary Schools and for replacement of the Estabrook School. Later that spring, at Special Town Meeting on April 2, 2012, Town Meeting voted to appropriate money for those repairs. In August, the School Committee was invited to see the new boiler room - an extended space at one far corner of each school. (Bridge and Bowman are identical buildings.)
I snapped the exciting images of the new boiler room (below), complete with shiny new pipes. The new boilers are much more efficient and slightly larger than a standard kitchen refrigerator. Compare that to the previous boilers, which when removed, provided space for two classrooms!
