A sulfidated, colloidal zero-valent iron amendment with high reactivity and extended longevity for in situ chemical reduction of groundwater contaminants.
Long-lasting, easy-to-apply sulfidated zero valent iron
S-MicroZVI® is an innovative colloidal zero-valent iron (ZVI) suspension (40% by weight, <5 microns) designed for in situ chemical reduction (ISCR). Manufactured with a proprietary sulfidation process, it offers enhanced reactivity, longer performance, and supports both abiotic destruction and ISCR-enhanced bioremediation.
What is it?
S-MicroZVI is an advanced zero-valent iron amendment designed for in situ chemical reduction (ISCR). Delivered as a <5-micron colloidal suspension (40% ZVI by weight in glycerol), it is manufactured with a sulfidation process that enhances reactivity toward chlorinated solvents and extends treatment life.
How does it work?
S-MicroZVI reduces contaminants on contact abiotically and creates conditions that stimulate ISCR-enhanced bioremediation. This dual action accelerates contaminant breakdown while sustaining long-term treatment performance.
Is it right for my site?
S-MicroZVI is effective for treating chlorinated solvents and other reducible compounds. It is commonly applied at industrial and manufacturing sites where persistent groundwater contamination requires a durable, in situ solution.

Pump-and-treat system replaced with effective combined remedy to treat CVOCs
A downtown Las Vegas site is being redeveloped after the successful in situ treatment of a chlorinated solvent plume caused by a historic dry cleaner release. Atlas, the environmental consultant, partnered with REGENESIS to implement a combined remedy using 3DME, SMZVI, and BDI Plus, following a successful pilot study. This approach replaced the costly pump-and-treat system, achieving faster remediation and preventing offsite migration, ensuring safety for nearby residents and cost-effective site closure.
Key benefits
Easy to apply
Disperses into groundwater
