Where is MTBE most likely found?

NAWQA findings indicate that MTBE is most frequently detected in ground water underlying urban areas in comparison to agricultural and mixed land-use settings. MTBE was detected in about 14 percent of wells sampled in urban areas. In addition, incidence of MTBE increases in high-use areas. Most of MTBE's high use occurs in Reformulated Gasoline (RFG) areas, where gasoline contains 11-percent MTBE by volume. MTBE has been detected about 4 to 6 times more frequently in the high-use areas than elsewhere.
