Methyl tertiary-butyl ether
MTBE (methyl tertiary-butyl ether) is almost exclusively 
used as a fuel additive in motor gasoline. It is one of a group
of chemicals commonly known as
MTBE is an ether with high water solubility (50.000 Mg/L) 
and relatively low volatility. Because of the low octanol
water distribution coefficient (log Kow= 1,06) it will
not be sorbed to the soil particles but can be transported
quite far in the groundwater. MTBE can be slowly biodegraded
in the soil and groundwater environment both under aerobic
and anaerobic conditions, although reports on degradation
rates under anaerobic conditions are conflicting.
Remediation of MTBE contaminated sites is complicated
because of the rapid spreading of the compounds. In situ
or on site bioremediation/pump-and-treat seem to be the
most feasible remediation options in most cases.
