Introduction. The Poly Carb site had phenol- and cresols-contaminated soil. The objective was to explore the use of innovative on-site technologies as an alternative to the transportation and off-site disposal of soil.
Biodegradation. Shake flask tests with genetically-enhanced microorganisms appeared promising to biodegrade soil-bound phenol and cresols. However, Evangelista created soil column studies using Poly Carb soil that showed the addition of these “supercharged bugs” did not improve biodegradation compared to columns containing only indigenous soil microbes. These indigenous microbes were well adapted to degrade soil contaminants. Efforts then focused on enhancing the biological activity of these “local” microbes to remove phenol and cresols from soil.
