Although quantification of Dehalococcoides has become an indispensable component of assessment, remedy selection, and performance monitoring at sites impacted by chlorinated solvents, additional bacterial groups such as Dehalobacter spp. and Dehalogenimonas spp. can play key roles in reductive dechlorination of chlorinated compounds. Moreover, reductive dechlorination is not the only potential biodegradation pathway – some chlorinated compounds are susceptible to aerobic (co)metabolic biodegradation mechanisms.
The QuantArray-Chlor not only provides quantification of a variety of halorespiring bacteria (Dehalococcoides, Dehalobacter, Dehalogenimonas, Desulfitobacterium, etc.) to assess the potential for reductive dechlorination of chloroethenes, chloroethanes, chlorobenzenes, chlorophenols and chloroform but also includes quantification of functional genes involved in aerobic (co)metabolic pathways for biodegradation of chlorinated solvents and even competing biological processes.
When combined with chemical and geochemical groundwater monitoring programs, the QuantArray provides site managers with the ability to simultaneously yet economically evaluate the potential for biodegradation of a spectrum of common chlorinated contaminants through a multitude of anaerobic and aerobic (co)metabolic pathways to give a much more clear and comprehensive view of contaminant biodegradation.
