Rula Deeb, Eric Suchomel to Discuss Emerging Contaminants at California Symposium

Rula Deeb, Ph.D., BCEEM, PMP, a principal civil and environmental engineer for Geosyntec Consultants based in California, is the co-chair of an upcoming symposium on emerging contaminants.

The event, hosted by the Groundwater Resources Association of California (GRA), will be held February 4-5, 2014, at the Concord Hilton, 1970 Diamond Boulevard in Concord, California. A full agenda is now available online.

Dr. Deeb will provide an overview of the symposium the afternoon of February 4. Eric Suchomel, Ph.D., P.E., a senior environmental engineer for Geosyntec based in California, will be a moderator for a technical session, "Other Contaminants of Emerging Concern," beginning at 1:15 p.m. on February 5.

"Emerging contaminants present numerous technical and institutional challenges to society and to environmental and public health professionals," Dr. Deeb said. "Increasingly sensitive analytical techniques have detected the presence of previously unregulated chemicals in actual or potential sources of drinking water throughout the nation."

"In some cases, the impacts of these chemicals to human health and the environment are uncertain," she said. "Many emerging chemicals remain unregulated, but the number of regulated contaminants will continue to grow slowly over the next several decades."

Speakers and presenters at the GRA symposium will profile the latest developments in detection, risk assessment, remediation, and regulation of emerging contaminants in groundwater. Experts from academia, regulatory agencies, and the legal arena will participate in moderated speaker sessions, poster sessions, and round-table panel discussions throughout the two days. A summary of the proceedings is available in a report in the Spring 2014 issue of the GRA's HydroVisions.

At Geosyntec, Dr. Deeb provides strategic consulting for environmental remediation challenges, litigation support, and research and development into new techniques and solutions that aid in site investigations and the characterization of a wide range of emerging contaminants.

Her work during the past 20 years has promoted awareness and improved the understanding of the sources, occurrence, fate and transport, and behavior of several of the most challenging environmental contaminants to date.

Dr. Suchomel joined Geosyntec in 2006. His practice focuses on site investigations and the characterization, design, and implementation of soil, groundwater, and soil vapor remediation systems; litigation technical support; and remediation technology research and development.

Among Dr. Suchomel's current projects is one that focuses on the development and demonstration of innovative technologies for the remediation of an emerging contaminant called 1,2,3-trichloropropane (TCP). This chlorinated hydrocarbon was historically used as an industrial solvent, as a cleaning and degreasing agent, and in the production of pesticides. It is currently used as a chemical intermediate in the creation of several other chemicals.
