Working with public and private sector clients, Geosyntec provides innovative redevelopment strategies for Brownfield sites worldwide. From site identification, investigation, and remediation to design, permitting, and construction management, we provide the services necessary to redevelop an environmentally impacted property to an end use that meets environmental stewardship and regulatory compliance. We solve our clients' Brownfield redevelopment challenges using innovative environmental remediation approaches as well as geotechnical engineering solutions.
Geosyntec approaches each Brownfield site individually by tailoring investigations, risk assessments, and remediation approaches to the clients' end use plan. We work with stakeholders including regulators, developers, and insurance providers to realize the full economic and social value of their site; working as a team creates a solution amenable by all parties as development progresses. Geosyntec's expertise in regulations, risk assessment, soil and groundwater remediation, soil vapor mitigation, geotechnical and geoenvironmental engineering, and solid waste and environmental management means we can work with stakeholders from start to finish providing consistency and reassurance that the environmental elements of development are being managed by one firm.
Grant Programs: Geosyntec offers assistance with grant application preparation and financial analyses for clients considering participation in government-sponsored Brownfield programs.
Site Assessments: Our environmental management specialists perform Phase I due-diligence services in accordance with ASTM E 1527-05 and following up, as needed, with Phase II site investigations.
Risk Assessments: Geosyntec's in-house toxicologists and risk assessment specialists perform risk assessments specific to end use goals. Working with developers, we can recommend optimized site layouts to take advantage of variable site conditions and limit the effects of environmental impacts to site development. Often this can lead to implementation of more cost-effective engineering controls for contamination rather than more costly and more extensive remedial measures.
Geoenvironmental Engineering: Our geoenvironmental and geotechnical engineers develop design approaches to stabilize, contain, and control conditions beneath foundations to allow construction of buildings, parking lots, or other developed surfaces to meet end-use goals on previously unusable or unstable ground.
Vapor Mitigation: Geosyntec's patented sub-slab vapor mitigation system effectively breaks the exposure route for indoor air, reducing potential hazards and allowing building development over impacted areas of the site. Our engineers also develop site specific vapor control, vapor monitoring, and vapor barrier designs that work hand-in-hand with the development team's foundation and architectural design elements.
Green Energy: Our engineers assess both the engineering and regulatory feasibility of green energy development on impacted sites. We provide permitting services, preliminary design, and site improvement recommendations to support wind and solar energy development.
Construction Services: Geosyntec's in-house construction services group provides constructability reviews, bid support, construction quality assurance, and construction management services. The construction services group checks that the design is constructible before implementation and the design is built correctly, on-time, and on-budget during construction.
Advancing the State of the Practice
Geosyntec's practitioners are advancing the state of the practice by writing the guidance documentation, teaching courses, and acquiring design patents that enable Brownfield redevelopment. We are frequently the preparers of vapor intrusion guidance mandated by State Agencies, and we were one of three primary authors for the United States Environmental Protection Agency's supplemental guidance on vapor intrusion. Working with the Interstate Technical Regulatory Council (ITRC), Geosyntec personnel taught a training course on vapor intrusion, including mitigation options for the development of vapor-impacted Brownfield sites. Geosyntec wrote the guidance document on evaluating, optimizing, or ending post-closure care at impacted sites, including Brownfield sites, and is working with regulators to incorporate our approaches into regulations. If incorporated, more effective site-specific closure approaches would be created versus the prescriptive approaches currently in place. Additionally, we have developed a patented approach for sub-slab vapor migration mitigation allowing residential, commercial, and industrial development on sites impacted by vapor intrusion.
