Description:
A pilot scale field demonstration of dense non-aqueous phase liquids (DNAPL) treatment using emulsified zero-valent iron (EZVI) is being conducted at Parris Island Marine Corps Recruit Depot (MCRD), Parris Island SC. The EZVI technology was developed at the University of Central Florida and the National Aeronautics and Space Administration (NASA) as a treatment technology for DNAPLs in the subsurface. EZVI consists of a surfactant-stabilized, biodegradable emulsion that forms emulsion droplets composed of an oil-liquid membrane surrounding micro- or nano-scale zero-valent iron (ZVI) particles in water. The emulsion droplets enhance contact between the ZVI and the DNAPL. The ZVI provides rapid abiotic degradation of the DNAPL constituents and the oil provides an immediate sequestration of the DNAPL constituents as well as a long-term electron donor source to enhance further biodegradation.
