Water wells with no detectable level of a gasoline additive can show high concentrations a few months later, a water treatment specialist told a New Hampshire jury considering whether ExxonMobil Corp. is liable for contaminating some of the state’s supplies.
ExxonMobil Corp. said in a trial over claims it polluted New Hampshire’s groundwater with a gasoline additive that the state’s own research indicates the chemical’s level will decrease over time without having to be cleaned up.
Citgo Petroleum Corp. reached an agreement with New Hampshire to be dismissed from an $816 million trial over groundwater contamination while a settlement is completed, as a witness testified that 2 percent of the state’s private wells are polluted with hazardous levels of the chemical MTBE.
