CONCORD, N.H. (AP) - The state of New Hampshire is launching its case against two major oil companies in what is expected to be the longest and most complex trial in state history.
The state's lawyers say ExxonMobil and Citgo should pay $700 million in damages to monitor and clean up groundwater contamination caused by the gas additive MTBE - now banned in New Hampshire.
Lawyers for the oil companies say they have cleaned up their own sites and that contamination elsewhere was caused by third parties not named in the suit.
The jury trial begins Monday and is expected to last four months. It is being held in a federal courtroom in Concord so as not to monopolize one of three courtrooms at Merrimack Superior Court.
More than 50,000 exhibits have been marked.
