The use of a “Thixotropic Gel for Vadose Zone Remediation", VOS™, is a significant advancement in the treatment of unsaturated soils. The unique thixotropic nature provides the ability of this gel to form a stable oil/water suspension that will remain in place after injection.  The substrate will maintain high saturation levels, sequester the contaminants, provide food for microorganisms and stimulate biodegradation activity. Initial results suggest that the VOS™ Technology can cost-effectively turn land once deemed unusable into productive and safe real estate.  We'll communicate more on these developments within the next couple of months.
