PCB Contaminated Soil Due To Intact Masonry Caulk

 

Here is a study that shows intact PCB-laden masonry caulking causing soil contamination.

This study contradicts the position held by state and federal regulatory agencies that PCB-laden caulk has to be in direct physical contact with the soil in order to cause contamination. Contamination is probably due to erosion, weathering and/or leaching of PCBs.
