Pluck v. BP Oil Pipeline Co.

An underground pipeline leaked gasoline five times between 1948 and 1962. After tests revealed benzene in wells, not including the plaintiffs' well, the company conducted remediation and monitoring and purchased the property now owned by the plaintiffs. The plaintiffs bought the property and a low level of benzene was detected in the well in 1996. The company installed a new well, which tested free of benzene 22 times between 1997 and 2002. Benzene was detected at a very low level in 2003 and the plaintiffs moved in 2005. In 2002 one of the plaintiffs was diagnosed, at age 48, with non-Hodgkins lymphoma. The district court entered summary judgment for the company. The Sixth Circuit affirmed. The district court acted within its discretion in excluding, as unreliable under the Daubert standard, an expert's specific-causation opinion. The expert did not ascertain the level of plaintiff's exposure and the level of benzene in the well never exceeded the EPA's standard; the expert did not rule out other possible causes, such as the plaintiff's smoking.
