Remediation Technique Currently Used At Contaminated Sites
Soil Vapor Extraction applies a vacuum to unsaturated zone soil to induce the controlled flow of air and remove volatile and some semivolatile organic contaminants from the soil.
What Are Permeable Reactive Barriers
Permeable Reactive Barriers are subsurface emplacements of reactive materials through which a dissolved contaminant plume must move as it flows, typically under natural gradient. Treated water exits the other side of the permeable reactive barrier.
