It's MTBE not MTBT. It wasn't so much that MTBE is highly toxic, but that it's water soluble, so when underground storage tanks leak gasoline/MTBE, the MTBE reaches underground drinking water sources (aka groundwater) much faster than the more toxic gasoline. When MTBE was first added to gasoline in California I remember there were some issues with it dissolving gas lines in older vehicles.
