LONDON, ON, Canada, July 6, 2006 -- Methods for cleaning up the pockets of contamination that serve as sources of soil and ground water pollution at contaminated sites will be examined by engineers and scientists from around the world at the 1st International Conference on DNAPL Characterization and Remediation (DNAPL-1), to be held Sept. 25-28 at the Omni William Penn Hotel in Pittsburgh, PA. Government and industry have found that cleaning soil and ground water is not enough when dense non-aqueous phase liquids (DNAPL) remain behind in hard-to-reach areas of the subsurface. These pools of chemicals can slowly seep into groundwater, causing contamination to continue for years.

DNAPL-1 is devoted to solving this problem. Attendees will discuss regulatory goals and standards for source cleanup. They will assess the risks and benefits of cleaning or not cleaning sites. They will review the economics of remediation. And most importantly, they will learn about techniques to characterize and remediate DNAPL and to monitor technology performance and cleanup progress.

Among other things, sessions will cover regulatory issues; economics; modeling and risk assessment; site characterization technologies, such as percussion probing, UV fluorescence, the membrane interface probe, geophysical imaging and soil gas surveys; DNAPL remediation technologies, including fluid flushing, thermal treatment, chemical oxidation and reduction and microbial degradation; performance monitoring and case studies. Regulators, researchers and those involved in technology development and application are invited to make oral and poster presentations. A limited amount of exhibit space is still available for companies involved in DNAPL characterization and remediation.

Additional Technology Meetings
Two long-running conferences on advanced pollution control technologies will be held simultaneously with DNAPL-1. The 11th International Conference on TiO2 Photocatalysis: Fundamentals and Applications, will cover topics ranging from purification and treatment of air and water streams to reactor design, application of TiO2 materials, nanotechnology, solar energy conversion, coating technology and technology transfer. The 12th International Conference on Advanced Oxidation for Treating Water, Air and Soil will cover chemical oxidants, ultraviolet light oxidation, electron beam and gamma irradiation, non-thermal plasma technologies, catalytic oxidation and reduction technologies, supercritical and subcritical water oxidation, biological oxidation and reduction processes, the integration of advanced oxidation and biological technologies, as well as other processes.

These conferences are presented by Redox Technology Inc. (www.redoxtech.com), of London, Ontario, Canada, which has brought scientists and engineers together to discuss advanced oxidation technologies for pollution control since 1994. The company also is conducting the 1st European Conference on DNAPL Characterization and Remediation and the 3rd European Conference on Oxidation and Reduction Technologies for In-Situ Treatment of Soil and Groundwater on Sept. 11-13 in Gottingen, Germany.
