Site Characterization for Remediation Projects

Wednesday, April 14, 2010: 11:05 a.m.-12:05 p.m.
Continental C (Westin Tabor Center, Denver)
Understanding the geology, hydrology, and geochemistry of a contaminated formation is critical to groundwater modeling, wellfield design, and remediation design. Information collected about site geology may include geologic cross-sections, lateral continuity of saturated zones, and hydraulic communication between adjacent formations. Important hydrologic information includes hydrologic properties of formations, water levels in wells, groundwater velocity, dispersivity values, regional groundwater use inventory, and contaminant migration pathways. Geochemical characterization includes determination of adsorption characteristics and biodegradation. Once all characteristics of a site have been evaluated, remediation specialists can develop an action plan. This session includes abstracts that: • Showcase challenges associated with geologic, hydrologic, and geochemical characterization • present case studies that demonstrate the use of innovative methods for solving challenges • Developing effective remediation strategies.
