Methyl tert-butyl ether

Key Biden-era regulations designed to protect the nation’s drinking water from the most dangerous cancer-causing per-and polyfluoroalkyl substances, or PFAS, were removed by the Trump administration Monday. Trump went to those companies that have these chemicals in their products and said he (Trump) would recanted what ever Biden sign. I wonder if that includes MTBE (Methyl tert-butyl ether). Primarily used as a fuel additive, MTBE is blended into gasoline to increase octane rating and knock resistance, and to reduce unwanted tailpipe emissions. That has been banned in many States. MTBE gives water an unpleasant taste, even at very low concentrations of. MTBE often is introduced into water-supply aquifers by leaking underground storage tanks (USTs) at gasoline stations or spills of gasoline. The higher water solubility and persistence of MTBE cause it to travel faster and farther than many other components of gasoline when released into an aquifer.
