New Patent Opens New Avenues for Petroleum Hydrocarbon Remediation


Current research firmly overrides previous scientific belief that petroleum and other aromatic hydrocarbons do not respond to anaerobic decontamination. A recent patent license agreement between EOS Remediation and the full-service global consulting firm Delta Consultants adds a highly effective approach to EOS Remediationís stable of anaerobic bioremediation products, providing customers an innovative, cost-effective solution for petroleum hydrocarbon remediation.

New Patent Opens New Avenues for Petroleum Hydrocarbon Remediation
Raleigh, NC, July 16, 2009 --(PR.com)-- EOS Remediation and Delta Consultants have signed an exclusive patent license agreement, giving EOS exclusive rights to manufacture, use and sell Delta’s sulfate-enhanced technology for in situ remediation of contaminated groundwater. The patent includes a process for using high concentrations of sulfate to stimulate biodegradation of petroleum hydrocarbons (PHCs) other aromatic hydrocarbons and other contaminants susceptible to sulfate-reducing bacteria.

“This sulfate-based technology holds terrific promise for EOS customers facing the tough contamination challenges related to PHC and other hydrocarbons,” says EOS Remediation Director Gary Birk. “It has been remarkable to see the shift in scientific thinking on anaerobic remediation of sites contaminated with aromatic hydrocarbons. Not only does current research prove the effectiveness of the approach, but field studies demonstrate that sulfate-based bioremediation may be the preferred approach for PHC decontamination of groundwater. EOS Remediation is pleased to be the exclusive supplier of Delta’s new technology."

A recent British Petroleum/EPA study has concluded that most hydrocarbon plumes are anaerobic and depleted of sulfate. Other studies have drawn comparable conclusions. A remediation feasibility study for a former gasoline service station in Kalamazoo, Michigan identified sulfate-based decontamination as a first-line strategy for reclaiming the site and addressing threats to the municipal drinking water supply. Delta’s sulfate-enhanced technology – now marketed by EOS Remediation under the name EAS™ – was the chosen product for the project.

EAS™ stimulated 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. In addition, sulfate reduction consumes protons, which increases site pH and enhances methanogenesis. The reaction results in complete degradation of the BTEX components. Ongoing project results indicate that the EAS™ technology can cost-effectively turn land once deemed unusable into productive real estate.

“This license agreement with Delta enables us to expand our strong foundation of intellectual property,” says Birk. “Working with the outstanding scientists and engineers at Delta will provide us more design freedom as we develop the next generation of bioremediation technologies and solutions to meet the demands of this ever-expanding environmental sector.”
