Vapor Intrusion Mitigation
Thinking beyond standard mitigation systems. With thousands of commercial, industrial, and residential buildings mitigated by our experts within the last 20 years, we know where to find cost-saving opportunities while maintaining or improving system effectiveness.
Vapor Intrusion Site Characterization
Vapor intrusion or background sources? With the potential for human health concerns, our clients cannot wait. Our techniques and forensic tools provide clients with rigorous, defensible data as quickly as possible: Building pressurization control (BPC) Real-time field tests (e.g., portable GC/MS, mobile labs) Mass flux testing Passive indoor air and soil vapor sampling, with tools like the Waterloo Membrane Sampler™
Vapor Intrusion Assessment & Remediation
When a site involves volatile organic compounds (VOCs) in soil or groundwater, those chemicals can volatilize and migrate into nearby buildings presenting a health hazard to those inside. Not only that, but most buildings also contain other sources of volatile contaminants that are related to ongoing operations or consumer products. Because the same chemicals can be present in the subsurface, in chemicals used on-site, and in other products, investigation and mitigation can become complicated.
Overview of Contaminated Site Assessment and Cleanup
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.
