Title: National Secondary Drinking Water Regulations (NSDWR): Methyl Tertiary Butyl Ether (MTBE) and Technical Corrections to the NSDWR | |
Abstract: Methyl Tertiary Butyl Ether (MTBE) is an automobile fuel additive, introduced in the late 1970s during lead phase-out as an octane enhancer. It has been used in increasing quantity in the 1990s to meet the requirement of the federal Reformulated Gasoline (RFG) and Oxyfuels programs required by the Clean Air Act Amendments of 1990. However, MTBE has been detected in ground water and drinking water in a number of states due to leaking underground storage tanks and leaking pipelines. Although most of these detections are at levels well below health concern, MTBE's distinctive turpentine-like taste and odor can be detected at low levels. Presently, the Agency is revising the health assessment for MTBE. | |
