Subject: Recent technical publications re: In situ bioremediation of PCBs.
The following reports or publications have come to my attention. The documents
are not in my possession and need to be ordered to see if they contain
information useful in Warren County.
1. Anaeobic degradation of PCB in soils, L. Haluska, et al. Int J Environ Anal
Chem, 58:1-4 (1995), p. 327.
2. Degradation of PCB by bacteria isolated from longfime contaminated soils. K.
Dercova, et al, Int J Environ Anal Chem, 58:1-4 (1995), p. 337.
3. Several presentations at recent American Society for Microbiology meeting
June, 1995 Washington, DC. Must be requested from author since proceedings
of meeting will not be available for almost a year.
Dennis Focht, UC Riverside, reported addition of terpene-containing
waste plant material (orange peels, pine needles, ivy leaves, or
eucalyptus leaves) caused vertual elimination of PCBs in soils
contaminated with PCBs by stimulating native bacteria to break down the
terpenes which translated to PCB dechlorination.
Donna Bedard from GE reported commercially available chemical that
when added to PCB-contaminated anaerobic sediments accelerated the
dechlorination step to 4 months.
