PCB Contaminated Soil/Concrete Remediation

PCBs are no longer commercially produced in the U.S., but were once widely used in older electrical equipment (transformers, capacitors), in window caulking and in fluorescent light fixtures (ballasts). PCB usage in transformers was beneficial due to their electrical insulating properties and chemical stability. Caulking materials incorporated PCBs as plasticizers in the 1950’s and 1960’s and are increasingly being detected during facility surveys in window glazing. PCBs were also used in capacitors within fluorescent light ballasts prior to 1979, and must be managed and disposed properly.

When transformer leaks occur, PCBs can contaminate the concrete pads supporting the transformer and often the soil beneath. These soils must be remediated to avoid long-term and potentially wide-ranging impact, and the contaminated concrete must also be properly disposed.

The professional team at TEC has extensive experience at Federal facilities managing and remediating PCB-impacted property and facilities.
