This document summarizes a presentation on sustainable remediation of soils and groundwater contaminated by chlorinated solvents. It discusses: 1. The widespread historical use of chlorinated solvents like PCE, TCE, and vinyl chloride in industry, which led to their release into the environment through production, use, storage and disposal. 2. The environmental and health challenges posed by chlorinated solvents, which are dense, immiscible liquids that can sink and persist in groundwater for decades. PCE contamination in particular can spread over large areas. 3. Treatment technologies for contaminated sites, including containment, pump-and-treat, and in situ chemical/biological transformations. Sustainable re
