One of the main reasons that site remediation fails or produces less than optimal outcomes is a reliance on an overly simplified CSM. Geosyntec addresses our clients’ toughest challenges, including contaminated media investigations, feasibility studies, and remediation system designs. CSMs are included at many of our most successful contaminated site assessments and cleanup efforts. CSMs identify data gaps, guide further site characterization, and are a primary planning and decision-making tool to identify and manage site uncertainty to support site management and remediation decisions. The models Geosyntec prepares range in size and complexity but provide key stakeholders with a solid framework for understanding site-specific. Armed with the clarity of data, narrative descriptions, and graphic visualizations of various impacts presented by our CSMs, decision makers are better able to choose a course of action that expedites restoration efforts, provides superior results, and delivers significant cost savings during the course of remediation to support site closure. Geosyntec's CSMs can be either written or visual documents, reports, graphics, or 3- and 4-D visualizations that represent the conditions and the physical, chemical, and biological processes that control the transport, transformation, and potential impacts of contaminants in soil, air, groundwater, surface water, and sediments. They also help identify human and ecological exposure pathways that may be present at an impacted site. A CSM developed by Geosyntec practitioners is an iterative tool which generally begins with the collection of existing data on impacted sites, including historical maps and records, surveys and data, site operating records, and aerial photographs. We then organize and analyze known sources of contamination and potential contaminants. Potentially contaminated areas and affected media are identified and potential migration routes, exposure pathways, and receptors are located. Typically, site investigations then begin to confirm our initial data and identify any gaps in the information. An important stage in the development of a CSM is the identification of crucial processes that influence contaminant transport, transformation, and response to remedial treatment. A range of tools, from simplified renderings to more complex visualization tools, are used to capture and communicate existing information and focus future data collection to fill data gaps and reduce key site uncertainties. We update CSMs as projects proceed to a level of detail matching the complexity of site conditions, the availability of data, and closure strategy. Geosyntec’s CSMs are objective-driven and designed to support the data quality objectives process that provides defensible data and supports robust decision-making such as cumulative risk, remedy selection, remedy implementation, site completion, and site reuse. They also aid clients in their efforts to communicate effectively with interested parties about the critical issues or processes identified at the site. Geosyntec practitioners are cognizant of best-practice guidance and adopt practices that meet the specific regulatory frameworks for the preparation and submission of CSMs. QUICK QUAL No pages found in your document.
