• Geosyntec scientists pioneered the use of bioaugmentation to enhance biological processes in groundwater • SiREM, a division of Geosyntec, has developed and commercialised multiple biological cultures that efficiently degrade specific contaminant groups, now available in Australia • Geosyntec scientists and engineers are active in applied research and development on various aspects of bioremediation design, including the use of partitioning donors to enhance biodegradation of NAPLs, development of molecular biological tools, bioremediation of emerging contaminants, and enhanced distribution of electron donors in low permeability units using electrokinetics. http://practices.geosyntec.com/bioremediation Bioremediation Geosyntec led the development of a successful groundwater remediation strategy at Aberdeen Proving Ground. We developed detailed designs for six sites and assisted in negotiations with regulators to achieve Agency approvals. Sustainable Solutions. Partner-Level Involvement. Geosyntec is a reliable partner for creative, cost effective and successful solutions because we approach remediation with an environmental management perspective. For each client, we develop a clear understanding of how to achieve best-value outcomes using the most appropriate technologies and management strategies for each project. Innovative Technologies. Practical Applications. Our professionals set the standard for engineered control of processes for environmental remediation. From advanced vapour intrusion evaluation strategies to sophisticated bioaugmentation techniques and beyond, Geosyntec delivers practical environmental management solutions that meet project-specific needs and achieve our clients’ objectives. Research Leaders. First-to-Field. Geosyntec scientists pioneered the use of bioaugmentation to profoundly refashion in situ biodegradation processes in groundwater. Our scientists are active in applied research and development with the DOD ESTCP and SERDP programs, NASA, the University of Western Australia, the University of Toronto, and others on topics such as bioremediation, metals biogeochemistry, reactive metals, chemical oxidation, waste water treatment, vapour intrusion, and the treatment of energetic, chlorinated and recalcitrant compounds and dense nonaqueous phase liquids. Our skill and experience implementing in situ bioremediation creates high-value solutions to complex groundwater and soil contamination and related issues at lower cost than competing approaches. INNOVATION AND COMMERCIALIZATION Geosyntec has been at the forefront of developing bioremediation as a sustainable alternative low-cost treatment technology. Client Service. Project Solutions. At Geosyntec, our vision of success builds on a long-held belief that exceptional client service coupled with exceptional project solutions will result in long-term business relationships of mutual reward. We support our client service and project solutions approach through an internal culture of technical excellence and collegial relationships, common commitment to our core values, and the innovation and practical thinking our staff bring to every assignment.
