Sequestration of heavy metal impacted soil and groundwater Remediation is a remedial technology that has been employed for many years around the world by highly specialized remediation engineers who understand the chemistry well and its application. High reactivity and high purity MgO is much more than a low cost chemical buffer for pH control.

Sequestration is a process where chemical reagents like Metals Treatment Solution (i.e. MTS®) are applied or injected into soil or groundwater, industrial waste or substrate to form a stable and insoluble precipitate resulting in reduced leachability of the target heavy metals.

Heavy metal sequestration chemically binds metal ions in the free liquids and immobilizes them within the soil / substrate thereby reducing their solubility through the chemical reaction. The physical characteristics of the sequestrated or “stabilized” contaminated material is not changed by this process with respect to geotechnical properties for redevelopment. It also does not interfere with biological systems or native biota if shallow enough to be in the root zone.
