Top Tips – Monitored Natural Attenuation

Summary:

This Top Tips bulletin explains how monitored natural attenuation (MNA) can be effectively evaluated and supported at petroleum‑impacted sites using multiple lines of evidence. It highlights how molecular biological tools such as QuantArray®‑Petro, CENSUS® qPCR, stable isotope probing, and in situ microcosms provide direct, defensible proof of biodegradation and help compare MNA with enhanced remediation options.
