Eliminating MTBE
Methyl tertiary butyl ether (MTBE) is a fuel oxygenate derived from petroleum—and has been the primary competitor to ethanol in the transportation fuel marketplace. However, MTBE has been shown to contaminate groundwater and it is listed as a possible carcinogen. Therefore, MTBE has been phased out across the United States.

Ethanol is non-toxic, water soluble and is the most harmless and biodegradable component of gasoline. When gasoline is spilled on land or in water, ethanol is the first component to quickly, safely and naturally degrade.
