EAS™, A Paradigm Shift in the Remediation of Petroleum Hydrocarbons: The conventional wisdom for remediation of aquifers contaminated with petroleum hydrocarbons (PHCs) is to add oxygen. A recent British Petroleum / EPA study, however, has concluded that most hydrocarbon plumes areanaerobic and depleted of sulfate and therefore, adding oxygen is disadvantageous. Other studies have drawn comparable conclusions. EAS™ is an anaerobic degradation process that facilitates natural attenuation of PHCs in the subsurface. This process occurs when terminal electron acceptor compounds such as nitrate, sulfate, and iron react to reduce PHC concentrations. The EAS™ process stimulates biodegradation by providing a soluble, readily available electron acceptor. In the presence of elevated sulfate, anaerobic groundwater bacteria use the PHCs for carbon and energy while mineralizing the hydrocarbons to carbon dioxide and water. EAS™ enhances natural conditions and reduces the carbon foot print when compared to conventional remediation.

Soil and groundwater clean-up is critical to sustainable business practices across many industries. The conventional wisdom for remediation of aquifers contaminated with petroleum hydrocarbons (PHCs) is to add oxygen. A paradigm shift in the remediation of petroleum hydrocarbons has occurred that employees a sulfate-enhanced in situ remediation strategy.
A recent EPA / British Petroleum study, however, concluded that most hydrocarbon plumes are anaerobic and depleted of sulfate and, therefore, adding oxygen is disadvantageous. Other studies have drawn comparable conclusions. EAS™ is an anaerobic degradation process (U.S. Patent No. 7,138,060) that facilitates natural attenuation of PHCs in the subsurface. Anaerobic degradation, mediated by terminal electron acceptors including nitrate, sulfate, and iron, is now firmly established and is considered to be the dominant driving force in the natural attenuation of PHCs in the subsurface.
EAS™ (Electron Acceptor Solution) stimulates biodegradation by providing a soluble, readily available electron acceptor. In the presence of elevated sulfate, anaerobic groundwater bacteria use the PHCs for carbon and energy while mineralizing the hydrocarbons to carbon dioxide and water. EAS™ enhances natural conditions and reduces the carbon footprint when compared to conventional remediation.
This presentation will provide information on anaerobic biodegradation of PHCs. The effectiveness of this cost-effective technology and case studies will also be discussed.

EOS Remediation wishes to congratulate Robert C. Borden, P.E., Ph.D., for receiving the 2010 Lifetime Achievement Award sponsored by Brown and Caldwell. As a Professor with North Carolina State University for 24 years, Dr. Borden has produced ground-breaking research on bioremediation and has mentored more than 60 master and doctoral students.
Dr. Borden’s academic research has translated into patented, market-valued bioremediation products, technologies and remediation approaches that have advanced both the field and the practical application of bioremediation.
Dr. Borden received the award at the Battelle International Conference on Remediation of Chlorinated and Recalcitrant Compounds on May 25, 2010. This is the sixth time Brown and Caldwell has granted a Lifetime Achievement Award. Dr. Borden joins the company of only five other pioneers in the field of aquifer remediation, among them Dr. Perry McCarty of Stanford University, Dr. John Wilson of the United States Environmental Protection Agency and Dr. Herb Ward of Rice University.
Dr. Borden is distinguished among this field because of the real-world, applicability of his science.
Dr. Borden’s publications alone provide ample evidence of his many contributions to the field. They can be viewed at www.myEOSRemediation.com, home of the EOS Library.

Acidic aquifers are inhibitory to many microbes. AquaBupH® adjusts pH without the negative effects of commonly used compounds like baking soda, caustic soda and limestone. These other methods also frequently yield high salt content in treated groundwater, pose handling hazards and/or require multiple applications. With a single treatment, AquaBupH® delivers immediate and sustainable bioremediation while improving one our most valuable natural resources: groundwater.
EOS Remediation has successfully completed projects in North America, South Africa, and Australia since launching the product. Because AquaBupH® is easy to distribute, easy to handle, provides for long-term remediation (2-3 years from a single application), and is cost effective, AquaBupH® represents a significant and innovative break through in the field of bioremediation technology. For more information on AquaBupH®, please visit: http://www.eosremediation.com.
Evaluation of trends in contaminant concentrations and geochemical parameters provides valuable, but indirect, evidence of biodegradation at contaminated sites. One direct avenue to assess the feasibility or effectiveness of bioremediation is to quantify microorganisms specifically responsible for biodegradation of the contaminants of concern (COCs). Nucleic acid (DNA) based technologies such as quantitative polymerase chain reaction (qPCR) or CENSUS are not dependent on culturing (growing) the microorganisms thus eliminating the biases associated with traditional plate counts and MPNs. CENSUS provides accurate quantification of microorganisms specifically responsible for biodegradation of COCs at costs comparable to traditional approaches. This presentation includes a brief introduction to qPCR. Available CENSUS assays for quantification of: Dehalococcoides spp. to assess PCE/TCE-impacted sites; TCE and vinyl chloride reductase genes; aerobic BTEX degrading bacteria; anaerobic BTEX degrading bacteria; and aerobic MTBE degrading bacteria are discussed. The presntation also includes examples showing how CENSUS results can be used to direct site management decisions at sites where EOS® products have been implemented.
