Vapor Intrusion Assessment and Mitigation Case Study

February 23, 2023

Vapor Intrusion Assessment and Mitigation Case Study

Technical Impracticability is a condition where remediation of ground water to the applicable standards is not feasible from an engineering perspective because of the limitations in the currently available ground water. This presentation discusses the challenges of TCE Remediation within a clay-rich unit, such as soil vapor extraction, in situ chemical oxidation, in situ thermal desorption and enhanced in situ bioremediation. Some keys to a successful technical impracticability evaluation are sound data collection, documentation and effective communication of site conditions and groundwater restoration potential.
