Rula Deeb (California) and Elisabeth Hawley (California), along with colleagues at UCLA and Caltech, were published in Environmental Engineering Science, the official journal of The Association of Environmental Engineering and Science Professors and a peer-reviewed journal from Mary Ann Liebert, Inc., publishers, Volume 33, Issue 9, September 1, 2016.
The application of enhanced in situ bioremediation for the treatment of chlorinated solvent source areas, referred to as dense non-aqueous phase liquid (DNAPL), offers major potential as a technically and economically effective remediation option. Project SABRe (Source Area BioRemediation) was designed to develop and demonstrate that enhanced anaerobic bioremediation can result in cost effective and quantifiable treatment of chlorinated solvent DNAPL source areas. Geosyntec was a key member of this collaborative project that was undertaken and financed by a multidisciplinary team from the United Kingdom, United States, and Canada, forming a unique industry-regulatory- academic partnership.
Geosyntec’s expertise in efficient site characterization, including sites that exhibit complex groundwater-flow regimes, has distinguished our firm as a leader in groundwater assessment and groundwater remediation. Our practitioners address a broad suite of contaminants, including metals, chlorinated organic chemicals, petroleum hydrocarbons, and emerging contaminants, and use award-winning, technology-based remediation strategies that are often first-to-field. Many of our hydrogeologists specialize in modeling the fate and transport of contaminants through the most difficult types of media, including fractured and karst bedrock.
Geosyntec practitioners rank among the world's top professionals in providing site assessment and remediation services at a wide range of impacted sites using innovative technologies and solutions that consistently advance the state of the practice. Through our use of innovative technologies and solutions, we provide our public and private sector clients with a wide array of services to address their toughest challenges. Our contaminated site practitioners guide our clients through a specialized remediation plan, consult on regulatory strategies, and develop a comprehensive cleanup approach. We can address numerous types of media, including contaminated soils, sediments, and groundwater. Advancing the State of the Practice Geosyntec's practitioners are pioneers in site assessment and remediation. Our senior practitioners have developed and authored guidance material and courses for local, state, and national agencies and associations on remediation techniques and technologies. Working with the Interstate Technical Regulatory Council, Geosyntec practitioners taught a training course on vapor intrusion, including mitigation options for the development of vapor-impacted brownfield sites. Geosyntec practitioners also wrote the guidance document on evaluating, optimizing, or ending post-closure care at impacted sites, including brownfield sites, and developed a patented approach for sub-slab vapor migration mitigation allowing residential, commercial, and industrial development on sites impacted by vapor intrusion. Our specialists routinely collaborate with prominent national researchers from academia and government agencies to provide innovative and defensible strategies for sites with contaminated sediments. For example, we collaborated with the United States Geological Survey (USGS) to remediate chlorinated solvent-contaminated marsh sediments by applying a bioreactive mat system embedded with a dehalogenating microbial consortium, a technology Geosyntec helped develop. This project and partnership earned our client recognition as a finalist for the Service to America Medal awarded by the Partnership for Public Service. Through a collaborative research project with the University of Florida, Geosyntec professionals helped develop the FLUCL software package for the Florida Department of Environmental Protection. This software is used to calculate exposure point concentration statistics in risk assessment and was the first of its kind to contain algorithms for censored datasets. FLUCL has received endorsements from several United States Environmental Protection Agency regions and the California Environmental Protection Agency. Geosyntec scientists also pioneered the use of genetic molecular tools to characterize microbes in environmental media and are engaged in applied research and development with top academic institutions around the world, including the University of Toronto, Cornell University, and the Georgia Institute of Technology.
Rula Deeb is a Senior Principal based in California with more than 25 years of experience focused on private practice and academia addressing the cross-media fate and transport of contaminants and the remediation of complex soil and groundwater sites impacted by nonaqueous-phase liquids and emerging contaminants.
Hydrogeological characterization and fate and transport modeling affects the performance of any remediation technology deployed at a site. To effectively remediate a site and optimize the use of time and resources, contamination must be sufficiently characterized using sound judgment to interpret available data. By delineating and understanding the geology and hydrogeology, our experts design strong conceptual site models, remediate groundwater, and employ beneficial reuse of sediments.
Understanding how water interacts with the surface and subsurface environment at any contaminated location is critical to designing innovative and cost-effective remediation systems and site-management strategies. By delineating and understanding the geology and hydrogeology affecting contaminated sites, our experts design strong conceptual site models and groundwater-remediation programs. Ultimately, hydrogeological characterization and modeling affects the performance of any remediation technologies deployed as a solution.
