PCBs [ Polychlorinated Biphenyls ]
Polychlorinated biphenyls [PCBs] are a family of man-made chemicals that contain 209 individual compounds with varying levels of toxicity. Because of their insulating and nonflammable properties, PCBs have been widely used as coolants and lubricants in transformers, capacitors, and other electrical equipment. The manufacture and use of PCBs in new products stopped in the U.S. in 1977 because of evidence that PCBs accumulated in the environment and could cause human health hazards. The University of Massachusetts has taken steps to abate PCBs on campus particularly in transformers and light ballast applications. As part of a recent LGRC facade repair and waterproofing project it was discovered that PCBs were used in some of the sealant caulking material. When this was validated the proper regulatory authorities [MDEP and EPA] were notified, the work involving the sealant material was stopped and an environmental engineering firm [EH&E of Newton, MA] was retained to assist in evaluating the situation and to make recommendations for engineering controls and remediation. This page is provided to post results of tests done by EH&E and to provide other useful links on PCB information. Click here for PCB Health Fact Sheet.
Update on Planned Actions for LGRC
Starting October 10, 2006, in accordance with state Department of Environmental Protection requirements, EHE will be taking soil samples around the exterior of the GRC buildings, primarily near Tower A and the Low-rise. Per state regulations the University must continue to act on the remediation of the contamination at the site.The sampling will involve two people from EHE taking core samples from the dirt around the building, samples of the debris in the storm drains, and possibly samples from the paved/bricked/concrete areas outside of the building. The sampling should not should not disturb any operations inside the building. There are also no health and/or safety concerns with the sampling. As a precationary meaure, those individuals taking the samples will be attired in appropriate personal protective equipment.
