Identifying the Source of Contaminants

ContaminantsCaseStudyThe environmental professionals at Brennan Environmental, Inc. (BEI) are experts at determining the source of site contamination. This expertise not only paves the way for effective site remediation, but has frequently helped clients prove that their activities or equipment were not the source of the contamination, saving them from extensive clean-up costs and protecting them from liability for contamination they did not cause.

Cases in point: BEI recently performed Site Assessment sampling at three different locations for a major utility, one of BEI’s many longtime clients. In the first Site Assessment, which included a Cleanup Response, vandalism had caused a large amount of dielectric fluid to be discharged from transformers owned by our client. It was alleged that contamination of soil in the area was due to the dielectric fluid leak. During the cleanup process, the BEI team identified odors in the soil, which led to a forensic investigation. The investigation determined conclusively that the source of the soil contamination was fuel oils and not dielectric oils. This finding saved our clients the costs of a large cleanup.

In another situation, an environmental consultant retained by a property owner discovered PCBs on the property. The consultant cited a transformer on the property that was owned by our client as the source of the PCBs. A due diligence investigation performed by the BEI team concluded that the type of PCBs found on the property had come from an adjacent property that had been deed-noticed for that particular PCB type. As a result of the finding, our client was held harmless for contamination.

In a similar situation, another environmental consultant engaged by a property owner found PCBs at the site and asserted that our client’s transformer was the source of the contamination. Through background investigation sampling, BEI proved that our client’s transformer had not leaked and did not contain PCBs. Subsequent borings performed away from the transformer area proved that the PCBs had come from a historic manufacturing facility that had been on the site, once again saving our client from a costly cleanup.
