Overview: This course provides a practical overview of chlorinated hydrocarbon site management, remediation principles, and proven technologies for soil, vapor, and groundwater. The training begins with a review of biogeochemistry and hydrologic factors that affect remedy selection and performance, followed by a discussion of common presumptive and innovative remedies. The 14-compartment model is used as a conceptual framework for discussing the order-of-magnitude performance of remedies within the various contaminant phases (dissolved, sorbed, vapor, and non-aqueous phase liquids). The course concludes with a case study demonstrating the application of the 14-compartment model to remedy selection and performance assessment. The information presented is applicable to a wide range of chlorinated hydrocarbon contamination including chlorinated benzenes, ethanes, ethenes, and methanes. Remediation of 1,4-dioxane will also be discussed.
