Why Are Environmental Remediation Services Important? Environmental remediation services are crucial for revitalizing contaminated land, protecting human health, and enhancing economic and ecological value. In a world filled with finite things let us preserve what we have left. Here are key benefits of environmental remediation: Improves the Environment Remediation transforms contaminated sites into healthy,…
Welcome to the captivating world of microbes! If you’re new to the concept or simply curious to learn more, buckle up as we discuss these tiny yet powerful organisms. What Are Microbes? Microbes, also known as microorganisms, are living organisms too small to be seen with the naked eye. They come in various forms,…
• 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.
– Site stakeholders needed conclusive evidence that biodegradation of benzene and naphthalene was occurring under existing site conditions to accept MNA instead of a more aggressive strategy.
– Stable isotope probing (SIP) studies using Bio-Traps® amended with 13C benzene or 13C naphthalene conclusively demonstrated in situ biodegradation occurred under existing site conditions.
• 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.
• 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.
• 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.
