Enhanced Attenuation of Unsaturated Chlorinated Solvent Source Zones Using Direct Hydrogen Delivery

ER-201027

Objective

At many contaminated DoD sites, unsaturated chlorinated volatile organic compound (CVOC) source zones located above the water table are producing and sustaining groundwater plumes. Current treatment options for the recovered vapors are both complicated and expensive.

The objective of this project is to demonstrate that hydrogen-based treatment can serve as a new remediation technology for the unsaturated zone, either as the initial remediation technology applied at a site or as a polishing technology, and that it will allow site managers to shut down expensive, low-performance soil vapor extraction (SVE) systems.
