Editing Bioaugmentation (section)

===Bioaugmentation of chlorinated solvents===
At sites where soil and groundwater are contaminated with chlorinated ethenes, such as [[tetrachloroethylene]] and [[trichloroethylene]], bioaugmentation can be used to ensure that the ''in situ'' microorganisms can completely degrade these contaminants to [[ethylene]] and [[chloride]], which are non-toxic.  Bioaugmentation is typically only applicable to bioremediation of chlorinated ethenes, although there are emerging cultures with the potential to biodegrade other compounds including [[BTX (chemistry)|BTEX]], [[chloroethane]]s, [[chloromethane]]s, and [[methyl tert-butyl ether|MTBE]].  The first reported application of bioaugmentation for chlorinated ethenes was at [[Kelly Air Force Base]], TX.<ref>{{cite journal|author=Major, D.W., M.L. McMaster, E.E. Cox, E.A. Edwards, S.M.
