SRS® ZVI Products
SRS®-EZVI products use a micelle-based EVO/ZVI formulation with a hydrophobic exterior that attracts chlorinated contaminants into a reactive zone. This targeted delivery enhances contact with ZVI, supporting effective abiotic degradation in DNAPL and high-concentration source areas.
