Demonizing for Dollars (Forbes.com) Forbes.com - To Texas litigator Scott Summy, methyl tertiary butyl ether, the gasoline additive that reduces air pollution, is the devil--and his savior. He claims to have proof that Big Oil knew that MTBE-laced gasoline would leak out of filling station tanks into the ground and contaminate water supplies across America--and is therefore culpable in a big public hazard. "We are talking about the public's drinking water, and these guys have intentionally contaminated it to the largest scale ever in this country," says Summy.
