MTBE and Anaheim Water

Anaheim Public Utilities’ drinking water wells contain no detectable levels of MTBE contamination.

MTBE, or methyl-tert butyl ether, is a gasoline oxygenate that was used in California from the early 1980s through 2003. Beginning in 2004, MTBE was banned in California because it was found to cause significant damage to groundwater when it was accidentally leaked to the environment. While California now uses ethanol as the federally mandated oxygenate, many areas are still cleaning up contamination from MTBE spills.

One of the things that Anaheim does to protect its groundwater is to focus corrective actions at gasoline stations where leaky tanks, pipes and/or dispensers allow gasoline to contaminate the environment. These cleanups, which are conducted per California Regional Water Quality Control Board guidelines, have helped prevent contamination of our drinking water aquifers. You can be assured that Anaheim will continue to advocate protection of its vital groundwater supplies.
