vermiculite carrier developed in the PAH project in the delivery of GEMs
for chlorinated biphenyl biodegradation.
We have documented a succinct progression of bench- and pilot-scale
demonstrations that applied sound scientific principles and assessed prac-
tical engineering issues in the development of enhanced parameters for
contaminant remediation. The major payoff of the work will come in the
future when successful bioremediation based on the achievement described
herein is used routinely to enhance cleanup of sites contaminated with PAHs
and other appropriate hydrophobic compounds.
The work funded under the SERDP program portrayed here has been
showcased in many venues, including national and international conferences
focusing on recalcitrant compounds, bioremediation, and microbiology; peer
review journals; and technical reports. A topic written for practitioners in
the field of bioremediation is planned in the near future. A device to monitor
microbial respiration during bioremediation and natural attenuation was
designed, tested, and submitted for patent during this study. This device is
a low-cost, low-technology means to decrease the costs associated with the
operation and maintenance of land-farming facilities without sacrificing
human health and safety.
