Groundwater Remediation

What is an in-situ methods to remediate a plume of chlorinated solvent contaminated groundwater in sandy soils? (process, different streams, disposal of byproducts, reagents used, equipment used, permit requirements, cost comparison, and factors that affect the selection process.)

Solution Preview

There are basically two methods of in-situ treatment of chlorinated solvent in groundwater: physical/chemical treatment methods, or biological methods. In situ solidification/stabilization detoxifies contaminants in the sediment by separating them from the environment, or by changing them into a chemically-unavailable form. Air sparging, directional wells, dual phase extraction, and fluid/vapor extraction are separation techniques. They are generally effective and relatively fast, compared to ...
