Surfactant-like compounds enhance the bioavailability of organic contaminants: Treatability results for a field demonstration
- Oak Ridge National Lab., TN (United States)
Methods to enhance rates of trichloroethylene (TCE) biodegradation were investigated during laboratory treatability studies in support of a field demonstration. Several commercially available nutrients with surfactant-like properties were assayed for their effect on enhancing TCE bioavailability and rates of degradation in soils with high clay content. The bacteria assayed were Methylosinus trichosporium OB3b (a methanotroph) and a heterotrophic consortium isolated from TCE saturated water. Several surfactants were added to 1 gram of site soil with the bacteria. Laboratory results showed that samples containing even low concentrations of surfactant compounds exhibited increased TCE partitionining into the liquid phase from the headspace, which correlated with an enhanced degradation rate.
