Injection services and chemistries

Cascade offers specialized equipment and chemistries for the treatment of chlorinated solvents, petroleum contaminants, PFAS, hazardous metals and more. 

Chemistries include zero valent iron (ZVI) and colloidal carbon. See below for more information on the specific chemistries.

Chlorinated solvent source zones can be remediated with an emulsified zero valent iron (ZVI). Cascade's SourceKill uses chemical reduction to target DNAPL source zones by placing micro-scale ZVI particles into a surfactant-stabilized, biodegradable water-in-oil emulsion. This emulsion is injected into the DNAPL-contaminated zones, sequestering the DNAPL into the emulsion.

Cascade's CleanER iZVI is a colloidal zero valent iron for chlorinated solvent remediation. This can also be applied to hazardous metals and herbicides/pesticides. CleanER iZVI primarily targets contaminants in transmissive zones down gradient of the source or in barrier applications but can also be used in to treat less contaminated source areas via chemical reduction. 

Cascade offers an Injectable colloidal carbon in FluxSorb IS for the treatment of chlorinated solvents, PFAS, BTEX, MTBE and more. Once injected, the particles demobilize and create an effective treatment zone for contact with the contaminated groundwater plume. As the water flows, contaminants are captured within activated carbon pores, where their concentrations are reduced.
