Exxon Mobil told to pay N.H. $236m

CONCORD, N.H. — Exxon Mobil Corp. was found liable Tuesday in a long-running lawsuit over groundwater contamination caused by the gasoline additive MTBE, and the jury ordered the oil giant to pay $236 million to New Hampshire to clean it up.

The verdict is more than twice the $105 million jurors awarded the New York City Water District in 2009 in its case against Exxon Mobil over MTBE contamination. That case is on appeal.

Jessica Grant, the state’s lead lawyer, said it was the largest verdict to date in an MTBE case. A financial analyst noted that the award represents about two days’ worth of profit for the company.
