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.
