Specialized In Situ Treatment Technologies

Geosyntec is an industry leader in remediating difficult-to-treat environmental impacts to soil, groundwater, and sediments through the use of specialized in situ techniques. Our practitioners are adept at expediting site investigations, optimizing remediation solutions, and accelerating site closure through a wide range of innovative technology applications. Our expertise in the implementation of new, emerging, and conventional technologies allows our practitioners to frequently bridge the gap between the development and first-to-field stages of environmental solutions.

Our expertise and industry leadership in the advanced application of microbiology-based solutions for the remediation of recalcitrant contaminants in soil and groundwater has established Geosyntec’s solutions as the preferred method, especially for sites with proven resistant to conventional remediation technologies or when compared to the comparatively high costs for the application of physical and chemical technologies that achieve similar results.

Two of Geosyntec’s affiliated companies provide specialized services and technologies regarding in situ treatments:

Savron

Savron is a multi-national provider of sustainable waste management and remediation solutions, specializing in the treatment of a broad range of hazardous materials. Its patented technology is an energy-efficient self-sustaining combustion process that captures and recycles the energy released from hazardous materials to destroy them in an effective, controllable, and safe manner through both in situ and ex situ applications. 

Savron’s STAR technology is an innovative in situ thermal technology based on the principles of smoldering combustion, where the contaminants are the source of fuel. The process is sustained by the addition of air through a well to the target treatment zone and is initiated through a short duration, low energy "ignition event." Once the process is initiated (ignited), the energy of the reacting contaminants is used to pre-heat and initiate combustion of contaminants in adjacent areas, propagating a combustion front through the contaminated zone in a self-sustaining manner (i.e., no external energy or added fuel input following ignition) provided a sufficient flux of oxygen is supplied.

SiREM

SiREM is widely recognized as a leader in bioaugmentation for chlorinated solvent remediation and bench-scale treatability testing applied to a wide range of remediation technologies, including in situ chemical oxidation (ISCO), in situ chemical reduction (ISCR), and bioremediation and permeable reactive barriers. SiREM also offers a range of laboratory testing services for remediation site monitoring, management, and optimization including Gene-Trac® testing for monitoring biodegradative microbes and other specialized analyses. It also produces the Waterloo Membrane Sampler™ (WMS™) for monitoring VOC vapor concentrations. Originally developed at the University of Waterloo, this sampler is a result of three years of applied research and is now available for commercial use.

Advancing the State of the Practice

Geosyntec scientists have pioneered the use of genetic molecular tools for the characterization of the 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.

Our practitioners also have performed research on multiple projects for NASA as well as the U.S. Department of Defense (DoD) under the auspices of the Strategic Environmental Research and Development Program (SERDP) and the Environmental Security Technology Certification Program (ESTCP). Through our active and long-standing association with the Interstate Technology and Regulatory Council (ITRC), our senior practitioners collaborate with state governments and the U.S. Environmental Protection Agency (EPA) to produce guidance documents and training courses for innovative application methods related to remediation of chlorinated solvents and other recalcitrant contaminants in groundwater.

In addition, Geosyntec's in-house laboratories provide physical and chemical testing that effectively monitors the performance of treatment processes, technologies, and systems. We produce field application quantities of naturally occurring consortia of microorganisms that target specific recalcitrant compounds. Using genetic testing, we can demonstrate the efficacy of these consortia in achieving containment reduction targets.

Our technical evaluation facilities regularly conduct chemical oxidation and bioreactor tests, examine the presence of organics and inorganics in wastewater, evaluate the effectiveness of remediation products, simulate the performance of conceptual designs, and analyze the likely behavior and end point of various treatment processes. All of our lab teams communicate regularly to share knowledge and direct internal and external client projects to the most appropriate technology solutions.
