The carcinogenicity of MTBE is still in question; the one Italian study that has so far obtained significant results has not been repeated. It's persistence in tissue and groundwater is not in question. Either way, it was a poor selection and in my judgment possibly corrupt. It may have even been a deliberate attempt to grab control of private water wells. To protect the children, you know.
The activities of another bloated State bureaucracy, the State Water Quality Control Board (SWQCB), have guaranteed that the big oil companies would have a monopoly in California and that prices would soar because it, SWQCB, systematically wiped out & bankrupted most of the small service stations in California by claiming that leaking underground fuel tanks were contaminating our water supplies and that this threat justified any amount of expense. However, scientists at the University of California in a published report recently confirmed that not even one percent of this purported threat to ground water ever existed.
