Remediation Chlorinated Solvents | REGENESIS

Cost-effective solutions to effectively treat chlorinated solvent sites

REGENESIS delivers turn-key in situ solutions that have been proven to quickly and effectively treat complex sites, enabling a wide range of clients to reach their site’s remedial goals.

Featured Case Study

Barrier treatment reduces chlorinated solvents at dry cleaner site

REGENESIS designed and implemented an in situ permeable reactive barrier (PRB) to effectively treat chlorinated volatile organic compounds (CVOCs) at a former dry cleaner. The barrier used a combined remedy of AquiFix®, PlumeStop®, sulfidated micron-scale ZVI (S-MicroZVI®), and Bio-Dechlor INOCULUM® Plus.

Contaminants treated

Chlorinated ethenes: perchloroethene (PCE), trichloroethene (TCE), dichloroethene (DCE), vinyl chloride (VC). Chlorinated ethanes: trichloroethane (TCA), dichloroethane (DCA) – and many more. For a full overview please see our Range of Treatable Contaminants.

Application methods

Injected under low pressure using direct push technology or via injection wells. Substrates may also be applied directly into excavations. Safe and easy to use in- and outdoors.

Advantages

In situ remediation is sustainable cost-effective and rapidly applied. Once injected, the remediation may be simply observed through groundwater sampling with no ongoing maintenance activities, operational cost or energy use.

In situ remediation approaches

Chlorinated solvent treatment barriers – Simultaneous remediation processes provided in a single treatment zone by combining our latest colloidal technologies, offering the most effective chlorinated solvent treatment available today.
