Soil Treatment
Our vision is to become an important player in the treatment and the transformation of contaminated soils, thanks to the deployment of high-performance fixed and mobile treatment units.

Our Expertise
Whether the issue is assessment/identification, treatment, removal, the answer is often “yes, we can”. We support our clients in the management of contaminated soils.

Exclusively accepted for treatment
By mobile unit
For the treatment of the following contaminants, Northex establishes a unique treatment plan for each site, these include:
Polychlorinated biphenyls (PCB)
- Treatment of PCB contaminated soil is possible. A physicochemical characterization of the contaminant in our laboratories will be necessary in order to establish a treatment plan. Contact us for more information.
Cyanide (CN-)
- Treatment of soil contaminated with cyanide is possible. A site characterization study will be necessary in order to formulate a treatment plan focused on the specifics of the site and the contaminant. Contact us for more information.
Dioxins & Furans
- The treatment of soil contaminated with dioxins and furans depends on the nature of the contamination. Contact us for more information.
Mercury (Hg)
- Like cyanide, treatment of soils contaminated with mercury is possible. A site characterization study will be necessary in order to formulate a treatment plan. Contact us for more information.
