PEPSystems™—plant growth-promoting rhizobacteria-enhanced phytoremediation systems—have been deployed across Canada for the treatment of soil contaminated with petroleum hydrocarbons (PHCs), including CCME fractions F2 and F3. In previous field trials of PEPSystems, PHCs were mostly degraded by microbes in the rhizosphere. Using new data collected from multiple commercial PEPSystems remediation sites across Western Canada, the kinetic equations of PHC decay were tested to determine if remediation time was accurately predicted. In general, when compared to the predicted time to remediation endpoint, data from recent commercial field applications showed that 35% and 20% less time was needed to reach remediation endpoints for fractions F2 and F3, respectively. As a result, the predictive kinetic equation for fraction F2 degradation was updated to reflect current remediation outcomes. Insufficient data were available to update the F3 equation. https://www.tandfonline.com/eprint/ayfpccwFKUi9gYPp5AqC/full?target=10.1080/15226514.2018.1523870.
