Molecular Tools, COVID-19 & EnviroTalk
EnviroWorkshops is hosting an amazing series on the impact of COVID-19 on our industry and we were honored to participate.
In Situ Microcosms: MNA vs Enhanced Aerobic Bioremediation
• The ISM study conducted at this site provided clear, actionable evidence that increasing the dissolved oxygen concentration at the site would stimulate hydrocarbon biodegradation. Further, this evidence was provided in a significantly more cost effective manner than a bench-scale treatability study or a pilot scale study and in a more timely manner.
QuantArray®-Chlor: Actionable Data for Remedy Selection
• 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 VC along with high concentrations of sulfate.
• QuantArray®-Chlor analysis provided actionable data for remedy selection allowing timely decisions and significant cost savings in site management.
QuantArray®-Chlor: Actionable Data for Performance Monitoring
• QuantArray®-Chlor analysis allowed site managers to have a comprehensive understanding of all relevant microbial processes at the site over time which allowed timely decisions and significant cost savings in site management.
ISMs: Cost Effective Remedy Selection at a TCE Impacted Site
• The ISM study conducted at this site provided clear, actionable evidence that electron donor injection would stimulate reductive dechlorination without the need for expensive bioaugmentation. Further, this evidence was provided in a significantly more cost effective manner than a bench-scale treatability study or a pilot scale study and in a more timely manner.
CENSUS® qPCR: Evaluating Biostimulation to Overcome DCE Stall
• A site impacted by PCE and TCE was experiencing an accumulation of cis-DCE (DCE stall). CENSUS® qPCR quantification demonstrated that Dehalococcoides concentrations were too low for effective rates of complete reductive dechlorination.
• Avoiding the expense of bioaugmentation resulted in significant cost savings while achieving treatment goals with biostimulation alone.
