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.

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.

Geosyntec applies reliable and innovative approaches to contaminated media investigations and assessments. We help clients address a wide array of known and emerging contaminants in soil, sediment, and groundwater. We also conduct site evaluations and discover the sources of air emissions, subsurface vapor intrusion into buildings, and contaminants in surface waters. Our assessment specialists include some of the most respected and sought-after professionals in the environmental remediation industry. They possess the experience and technical skills to conceptualize and implement all aspects of contaminated media assessments and remediation programs. Using a multidisciplinary approach, Geosyntec brings together nationally recognized, in-house specialists in civil and geotechnical engineering, ecology and biological sciences, risk assessment and applied toxicology, and earth sciences to address the complex issues associated with contaminated media. Our contaminated site practitioners guide our clients through specialized remediation plans, consult on regulatory strategies, and develop comprehensive cleanup approaches. We address numerous types of media, including contaminated soil, sediment, and groundwater. Contaminated Media Services

Conceptual Site Model Development

Developing an accurate conceptual site model (CSM) is paramount to understanding and interpreting contaminant fate and transport in the subsurface. One of the main reasons that site remediation fails or produces less than optimal outcomes is a reliance on an overly simplified CSM.

Regulatory Strategy & Cleanup Goal Development

Geosyntec provides practical solutions and a clear vision for environmental remediation that exceed client expectations and help them earn regulatory approval of the solutions they deploy. Dynamic environmental laws and standards and evolving remediation guidance demand proactive cleanup solutions and a clear strategy for addressing regulatory requirements in order for businesses to minimize environmental risk while maintaining economic benefit. Environmental remediation projects are often complex and multi-faceted. This means reaching regulatory closure is not necessarily just about reducing contaminant concentrations below a defined threshold. A range of stakeholders usually need to be satisfied that efforts have been genuinely spent in an attempt to result in better outcomes. A successful remediation project often requires stakeholders agree and own some of the key performance indicators; understand key milestones and their implications; and gain insight on the uncertainties and contingencies to address these. Geosyntec has acquired considerable experience in regulatory advocacy and stakeholder engagement in a range of jurisdictions across the globe. Our practitioners convey complex remediation strategies in a manner that these can gain support from a range of stakeholders.  We work closely with clients to develop risk-based closure strategy and criteria, advise on site closure and reuse options, and negotiate closure criteria with key regulators Stakeholder comments are addressed to achieve consensus and approval from multiple regulatory agencies. Our environmental compliance services include helping clients obtain permits through the U.S. Environmental Protection Agency's (EPA) National Pollutant Discharge Elimination System (NPDES) program and determining the regulatory compliance of a waste storage facility under the Resource Conservation and Recovery Act (RCRA). For example, for a sediment remediation project Geosyntec worked hand-in-hand with our client, the EPA Great Lakes National Program Office, and the Michigan Department of Environment, Great lakes, and Energy on a cost share partnership throughout the investigation and remedial design process. Through this interaction we were able to identify and design a project that not only met federal and state requirements but could be implemented within the client’s available funding. Geosyntec practitioners help negotiate cleanup goals with regulatory agencies during strategy development and, of course, steer clients through the implementation of long-term remediation plans with their goals as our foremost focus.
