Lessons Learned on Bioaugmentation of DNAPL Source Zone Areas
2007
Major, David | McMaster, Michaye | Lebron, Carmen A.
The ESTCP funded a pilot scale demonstration in which 100L of PCE were released in a test cell at Dover AFB. The purpose of the demonstration was to investigate the effects of biological activity on enhancing dissolution of the emplaced PCE source. Both laboratory and field tests were performed using biostimulation and bioaugmentation. Both laboratory and field efforts demonstrated that bioaugmentation can stimulate complete dechlorination to nontoxic end products. Lessons learned from the demonstration can be applied at other sites and include: a) the rationale for bioaugmentation, b) how to assess the need for bioaugmentation, and c) tracking system performance.
