Over the past decade there has been an increasing awareness of the past use of PCBs (polychlorinated biphenyls) in a variety of building materials such as caulks, sealants and mastics. While in their pure form PCBs are oily liquids, when they were used as an ingredient in building material they cannot be seen, smelled or detected with our senses. In the United States, PCBs have not been used in building materials for about 40 years, but since one of the purposes of using PCBs was to extend the life of building materials, they are still present in many buildings constructed or remodeled between approximately 1940 and 1970.
While PCBs in building materials have not been shown to cause harm, once discovered in these materials their continued use in a building is sometimes considered to be subject to the U.S. Environmental Protection Agency regulations. The laws and regulations governing the use and cleanup of PCBs are long and complex, even by federal government standards.
OTO is adept at the assessment and remediation of PCBs, and we have the skill set to assist in the identification and communication of risk and the degree of hazard posed by PCBs. Proper risk communication is often a vital tool in helping school systems and other institutions avoid expensive and frequently unnecessary remediation.
