Biological Activity<br />
• Complex mechanisms (e.g., cometabolism/beta-elim<strong>in</strong>ations/etc.)<br />
• CaCO 3 addition affected microbial activity (Feb 2012)<br />
• Geochemical shifts from buffer<strong>in</strong>g affected IRB/SRB activity<br />
• Reduced competition from preferential sulfate reduction<br />
• TCEr detected for the first time after buffer<strong>in</strong>g (substrate “peck<strong>in</strong>g order”)<br />
• VCr/BVC historically nondetect<br />
• Sharp TCE concentration reductions; VC consistently detected for first time<br />
