Fuel oxygenates, primarily ethers and alcohols, are added to gasoline to enhance the octane content and to improve air quality reducing the emission of pollutants, particularly carbon monoxide.

Fuel oxygenates can be found in aquifers as contaminants. Their introduction to the environment can be accidental through the release from underground pipelines, tanks and gasoline spills. Industrial wastewater as well as the petroleum fuel cycle process can also represent sources of oxygenates to the water.

The proof of the presence of oxygenates in drinking water has raised serious concern regarding the taste and odor aspects. Concerns also raised about possible human-health implications.

In the following application increased analytical performances and high reliability are obtained through the use of the Master GC coupled to the Master DHS/P&T.
