| Short description: |
Emulsified zero-valent iron (EZVI) is an innovative remediation technology that can be used to
enhance the destruction of chlorinated DNAPL in source zones by creating intimate contact
between the DNAPL and the zero-valent iron (ZVI) particles. The EZVI is composed of foodgrade
surfactant, biodegradable oil, water, and ZVI particles (either nano- or micro-scale iron,
nZVI, or mZVI), which form emulsion particles. 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.
This report summarizes the work conducted to demonstrate/validate the EZVI technology at
Parris Island Marine Corps Recruit Depot (MCRD) in South Carolina.
