WEBINAR: The Use of Cutting-Edge Molecular Microbial Technologies to Drive a Successful, Novel, Enhanced Bioremediation of Legacy Contaminants

June 8 @ 12:30 pm - 1:30 pm EDT


A comprehensive biogeochemical assessment was performed at a historical refinery impacted with benzene, a compound that is generating a resurgence in concern after having become a primary regulatory driver in many areas across the United States. The objective was to conduct a first-of-its-kind enhanced in-situ bioremediation (EISB) event to target benzene under anaerobic conditions.

The initial biogeochemical assessment merged an evaluation of traditional geochemical parameters with a unique consortium of innovative molecular biological tools (MBTs). Information gleaned from these studies was used to develop one of the first known EISB studies to target the in-situ enhancement of a specific benzene-biodegrading microbial population at a location such as this.

Results/Lessons Learned
To date, historical benzene concentrations within the treatment area have decreased up to 99%. This project demonstrates that the strategic combination of traditional site monitoring methods and cutting edge MBTs can provide critical information about indigenous biodegradation activities, maximizing the potential for successful EISB of targeted and recalcitrant contaminants. This presentation will outline this process, as well as results of the unique, cutting-edge bioaugmentation pilot-study that reduced legacy contaminants at the site by up to 99%.
