Oxygenated substances have been infused with oxygen. The term usually refers to oxygenated fuels. Oxygenates are usually added to reduce carbon monoxide that is created during the burning of the fuel. Some oxygenates such as MTBE have been found to have contaminated groundwater, mostly through leaks in underground gasoline storage tanks.
In 2004, California and New York banned MTBE, generally replacing it with ethanol. Several other states started switching soon afterward.

Assessing the transport and fate of MTBE - An article on the oxygenates MTBE and TAME and how they have led to contamination of major aquifers, including the Chalk aquifer of southern England.
Meta Description: [ The ether oxygenates MTBE and TAME have been used in petroleum fuel formulations in the UK since the mid-1980s and have led to contamination of major aquifers, including the Chalk aquifer of southern England. An assessment is made of the controls on the fate of MTBE, TAME and BTEX compounds at a ... ]
