The innovative QuantArray®-Chlor

16 February 2023


Given the wide range of microorganisms and metabolic pathways involved in chlorinated solvent degradation, QuantArray®-Chlor offers the most comprehensive and cost-effective method of evaluating the genetic potential for chlorinated solvent biodegradation at a site. The Chlor suite includes 29 gene targets covering reductive dechlorination and aerobic (co)metabolic pathways for chlorinated solvents as well as competing biological processes. Two new cases highlight how QuantArray®-Chlor data can be successfully leveraged to make more informed site management decisions during all phases of remediation.

In the first case study, site managers were considering monitored natural attenuation (MNA), biostimulation, and bioaugmentation as remediation strategies at a site impacted by a complex mixture of chlorinated hydrocarbons including PCE, TCE, 1,1,2-TCA, 1,2-DCA, cis-DCE, and vinyl chloride along with high concentrations of sulfate. They had several questions including: Is complete reductive dechlorination of all chlorinated solvents possible? Is biostimulation or bioaugmentation required?

In the second case study, electron donor injection was performed at a former chemical manufacturing facility impacted by a mixture of chlorinated compounds. Site managers relied on QuantArray®-Chlor to monitor the performance of the electron donor injection at this complex site to ensure complete reductive dechlorination of all chlorinated solvents, identify potential interfering of competing microbial processes, and make real-time site management decisions.
