For over a decade, QuantArray®‑Petro, has provided engineers a high‑throughput qPCR platform that simultaneously quantifies functional genes involved in aerobic and anaerobic biodegradation of petroleum hydrocarbons, including BTEX, PAHs, MTBE, and alkanes. QuantArray®‑Petro provides defensible microbial lines of evidence to support monitored natural attenuation (MNA), evaluate enhanced bioremediation, and guide petroleum‑impacted site management decisions.
Used by practitioners around the world since 2012, this paper describes QuantArray®‑Chlor, a high‑throughput qPCR platform that simultaneously quantifies key microorganisms and functional genes involved in the biodegradation of chlorinated solvents. QuantArray®‑Chlor provides comprehensive, actionable data to support site assessment, remedy selection, and performance monitoring for chlorinated groundwater remediation.
This technical bulletin explains how aerobic cometabolism and abiotic degradation can be critical mechanisms supporting monitored natural attenuation (MNA) at chlorinated ethene sites, particularly in large or dilute plumes. It describes how molecular biological tools, mineralogical analyses, and degradation rate studies provide defensible evidence of contaminant destruction beyond traditional groundwater trend analysis.
This technical bulletin explains how molecular microbiological methods improve the detection, mitigation, and monitoring of microbiologically influenced corrosion (MIC) across industrial systems. It highlights the use of QuantArray®‑MIC, qPCR, and next‑generation sequencing within a multiple lines of evidence framework to identify MIC threats, guide mitigation strategies, and protect critical assets.
This technical bulletin shows how molecular biological tools can be integrated throughout the stages of remediation (site characterization, remedy selection, performance monitoring, and closure) to improve confidence in bioremediation decisions. It highlights the use of qPCR, QuantArray®, in situ microcosms, and stable isotope probing to reduce uncertainty, optimize remedies, and support transition to monitored natural…
