Emulsified Zero-Valent Iron

NASA Kennedy Space Center (KSC) is proud to announce the successful commercialization of Emulsified Zero-Valent Iron (EZVI). This technology was designed for the in-situ treatment of dense non-aqueous phase liquids (DNAPLs) and is one of the few methods that can treat the DNAPL source. EZVI also overcomes limitations with current DNAPL treatment technologies by providing a method that is quick, effective, and cost-competitive. EZVI was originally developed by researchers at NASA and the University of Central Florida to treat chlorinated-solvent contamination at KSC's Launch Complex 34. Based on the success of laboratory and field tests, NASA licensed EZVI to six companies that are producing their own versions of the technology.
