Robust decision making processes in bioremediation by Prof Kerry Sublette

This session will focus on the application of BioTrap technology showing how analysis of the site microbiology can reduce costs and provide certainty when using remediation strategies involving natural or enhanced attenuation. Case Studies will include the use of baited biotrap to choose the best additive to stimulate reductive dechlorination of chlorinated solvents and Carbon 13 (13C) baited biotrap to provide unequivocal proof of petroleum degradation within the aquifer.

Dr. Kerry L. Sublette is Professor of Chemical Engineering and Geosciences and Sarkeys Professor of Environmental Engineering at the University of Tulsa. He also serves as the director of the Integrated Petroleum Environmental Consortium (IPEC). He earned his Ph.D. in chemical engineering in 1985 and worked for six years in research and development for Combustion Engineering before joining The University of Tulsa faculty. His research interests include bioremediation of hydrocarbon-impacted soil, remediation of brine spills, restoration of soil ecosystems, ecological indicators of soil ecosystem restoration, and microbial ecology of aquifers impacted by BTEX, MTBE, and chlorinated hydrocarbons. Dr. Sublette has over 20 years of experience in environmental engineering, over 100 peer-reviewed publications, and 13 patents. He also chairs the annual International Petroleum Environmental Conference and serves on the Oklahoma Board of Environmental Quality.


Thermal conductive heating is not only an effective in-situ remediation technique but also a complementary method for thermally enhanced microbial soil remediation by Anna-Maria Kozlowska

Latest achievements in the thermal conductive remediation technology for treatment of halogenated solvents. How the thermal treatment can be combined with enhanced biological degradation for sites where reductive dechlorination is the dominant biological step. Site specific details will be utilised to demonstrate the effectiveness of combined thermal and biological treatment. (Case Study, Harwell, Oxfordshire).

Anna-Maria Kozlowska Senior Chemical and Environmental Engineer at Provectus Group Ltd has been focusing on adaptation, design and implementation of new innovative remediation technologies for soil and groundwater treatment. She is responsible for coordinating and operation of the UK s first conductive heating thermally enhanced SVE scheme (accepted as a CL:AIRE Technical Demonstration Project). Anna-Maria obtained a MSc in Environmental Engineering from Technical University Hamburg-Harburg, Germany and was awarded a scholarship from Northern Institute of Technology (NIT) for dual MSc degree in Global Technology Management. Anna-Maria has over 7-years gained industrial and academic experience in chemical and process engineering application in the environmental field, incineration, composting plant, wastewater treatment design and optimisation.


Using the latest techniques in tracer systems that allows groundwater movements to be accurately tracked by Dr. Haydn Gregg Williams

EnviroTrace is a novel tracer system that allows groundwater movements to be accurately tracked. It has significant advantages over traditional dye tracers, as that multiple tracers each with a unique DNA tag can be simultaneously released and monitored with very high sensitivity. Also, as EnviroTrace is non-toxic, biodegradable and colourless and can be released where dyes would not be appropriate. Case studies describing the use of EnviroTrace to monitor groundwater flow under abstraction through gravel and chalk aquifers will be presented.

Dr. Haydn Gregg Williams is Business Development Manager and Contaminated Land and Groundwater Specialist at EnviroGene Ltd., focusing on the application of molecular diagnostics and tracing technology to enable informed capital expenditure for remediation projects and the management of essential natural resources. Gregg obtained a Ph.D. in Environmental Microbiology from Cardiff University and has over 15 years experience using molecular techniques in environmental and industrial settings. Gregg has managed several site investigation studies using BioTraps to assess, optimize and monitor the progress of biological remediation in sites contaminated with various hydrocarbons such as, BTEX, MTBE and chlorinated solvents.
