QuantArray®-Chlor during Site Assessment and Remedy Selection
The study site is a portion of a chemical manufacturing facility impacted by 1,1,2-trichloroethane (TCA), 1,2-dichloroethane (DCA), trichloroethene (TCE), and chloroform. Daughter products including 1,2-dichloroethene (DCE), vinyl chloride, and ethene have been routinely detected suggesting that reductive dechlorination has occurred to some extent historically. With a complex mixture of chlorinated compounds, the possibility of inhibition, as well as the potential for multiple and converging biodegradation pathways, QuantArray®-Chlor was integrated into groundwater monitoring to evaluate biodegradation processes under existing site conditions, potential remediation options, and ultimately performance monitoring (QuantArray-Chlor during Performance Monitoring).
QuantArray-Chlor Results and Interpretation
The Microbial Population figure for observation well OW3 shown below presents the concentrations of target poulations compared to typically observed concentrations to give an overview of the potential biodegradation pathways.
