Conclusions<br />

<strong>Bioaugmentation</strong> with <strong>KB</strong>-1 stimulated complete dechlorination<br />

Electron donor alone didn’t stimulate complete dechlorination<br />

Dechlorination rates were faster in the field than in microcosms<br />

Many sites contain indigenous DHC, there<strong>for</strong>e bioaugmentation not<br />

required at all sites<br />

<strong>Bioaugmentation</strong> will be required when<br />

– Dehalococcoides not detected<br />

– Microcosm or field results show incomplete dechlorination<br />

– <strong>In</strong>digenous populations <strong>of</strong> DHC are too low or incompetent to meet remedial<br />

goals within required time frames
