INDIANAPOLIS - A federal judge in the U.S. District Court for the Southern District of Indiana on July 7 ruled that a pollution exclusion in a company's insurance policy "unambiguously excluded" it from coverage for groundwater contamination caused by trichloroethylene (TCE) and other chemicals (Visteon Corporation, et al. v. National Union Fire Insurance Co. of Pittsburgh, No. 11-00200, S.D. Ind.; 2014 U.S. Dist. LEXIS 91578).
