Groundwater Remediation System Capture Analysis: Examples from Multiple Sites

Groundwater remediation systems are subject to periodic review by site remediation personnel, clients, and regulators. Since remediation systems run the gamut from small and simple systems to large and complex systems, a one-size fits all approach may not be warranted or appropriate. There are many ways to evaluate capture and a multiple lines-of-evidence approach helps to ensure that groundwater capture and the correlated containment and cleanup objectives are being met. This presentation will provide examples from various federal, state, and voluntary remedial action sites on groundwater capture evaluation each with differing levels of complexity related to hydrogeology, system design, and contaminant types. The approaches and methods used will be discussed and outcomes evaluated. General project costs for each of the types of evaluations will be provided to illustrate level of effort versus site complexity.
