Mealey's (August 30, 2019, 9:35 AM EDT) -- TRENTON, N.J. — An expert’s testimony that contaminated groundwater containing the gasoline additive methyl tertiary butyl ether (MTBE) traveled from the site of a gas station with underground storage tanks (USTs) to domestic water supply wells is reliable because it is based on sound methodology, a federal judge in New Jersey ruled Aug. 28 in denying three defendant companies’ motions to exclude the expert’s opinions under Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993) (New Jersey Department of Environmental Protection v. Amerada Hess Corp., et al., No. 15-6468, D. N.J., 2019 U.S. Dist. LEXIS 146336)....
