Once the decision to remediate a site has been made, the first step involves remediation strategy development. The basis for remedial strategy development is the conceptual site model (CSM), which is the concise depiction of the nature and extent
of impacts, the physical and biogeochemical conditions that affect fate and transport of contaminants, and the proximity of environmental receptors. The CSM outlines the “problem statement” that environmental remediation needs to solve.
Additionally, the end-state vision must also be defined (i.e., endpoints to be achieved and the necessary timeframe to achieve these). A remediation strategy is then tailored to move from existing site conditions to the target endpoint.
Trihydro has developed remedial solutions for some of the most complex sites in the country. With this experience, our remediation experts help site owners and operators understand and balance their goals with various regulatory frameworks. Remediation
projects also have the potential to attract public attention and can involve significant community outreach and education efforts. Trihydro assists clients in understanding stakeholder concerns and evaluating the degree of stakeholder communications
to include in their strategy. Where applicable, Trihydro assists in developing communication plans that help the public and other interested parties understand site background, project drivers, and timelines.
Remedial strategy development relies on a full understanding of site challenges. Trihydro's interdisciplinary team routinely develops CSMs to help clients visualize and understand their sites better. We also provide fate and transport modeling to
help illustrate where contaminants degrade or where chemicals travel within an environment upon release. We leverage existing data wherever possible and help fill data gaps through sampling or monitoring of media such as soil, soil vapor, groundwater,
and surface water. Filling data gaps and having a full picture of a site's makeup at the strategic development stage helps ensure subsequent project steps support clients' remediation goals. Having a complete CSM also helps pinpoint remediation
efforts to problem areas, saving money through a reduced treatment footprint.
Trihydro’s engineers and scientists have a deep understanding of the benefits and limitations of a wide range of remediation technologies. Understanding what a given technology can and cannot do is key to incorporating that technology into a
remediation strategy. This understanding is due in part to our team’s education, with many Master’s and Ph.D.’s staffing remediation projects. We continue to provide guest lectures on remediation subjects at local universities
and maintain our knowledge by attending (and presenting at) conferences and webinars.
Ultimately, remedial strategy development is a balancing act that considers site goals, regulations, and remediation technologies. Trihydro assists clients each step of the way, including acting as a guide through various technology screening processes
required by regulation, such as Feasibility Studies under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and Corrective Measures Studies under the Resource Conservation and Recovery Act (RCRA). We also assist
with understanding state-specific regulatory requirements and help confirm clients' remedial strategies account for needs such as Remedial Alternatives Evaluation Reports (RAERs).
