Groundwater Quality
The “Groundwater Quality” event is organized by the Bordeaux Polytechnic Institute and covers all aspects of groundwater quality and the pollutants it contains. It addresses the interactions between groundwater and surface water, remediation strategies from the laboratory to on-site application, emerging pollutants, microplastics and multidisciplinary approaches to maintaining groundwater quality.
Groundwater pollution and contaminated soil are a risk on people and the environment, which is why the treatment of contaminated sites and remediation is regulated by law.
Our soil and groundwater remediation team offers you remediation concepts and products for treating a wide range of contaminants in groundwater, wastewater and soil. We use both proven and innovative remediation approaches, such as the modern in situ process, which is suitable for both organic and inorganic pollutants. In situ remediation is economical and conserves resources because the remediation takes place directly at the site of the contamination.
Our portfolio includes products such as GEOFORM®, which promotes biogeochemical reactions, specialized METAFIX® Reagents for heavy metal treatment and EHC® for in situ chemical reduction.

Our Products for Combined Remediation Processes
GEOFORM®
GEOFORM® biochemical reagents provide the building blocks needed to drive biogeochemical reactions in situ. It is particularly suitable for the treatment of groundwater and saturated soils contaminated with metals or persistent halogenated compounds.
How GEOFORM® works
GEOFORM® rapidly establishes reducing (reductive) conditions by promoting both biotic and abiotic reduction mechanisms. The organic carbon serves as an electron donor for dechlorinating bacteria, stimulating biological reductive dechlorination. Under sulfate-reducing conditions, the formation of reactive iron sulfide minerals creates greater surface area for abiotic dehalogenation reactions. GEOFORM® Extended Release also promotes direct chemical reduction upon contact with ZVI.
Key Benefits
- Treats mixed plume with CVOCs and heavy metals
- Multiple pollutant removal mechanisms
- Improved dispersibility/reactive surface area

METAFIX®
METAFIX® offers a unique treatment approach for groundwater, soils, sediments and industrial waste contaminated with heavy metals such as chromium, lead, arsenic and mercury. METAFIX® reagents can be used to remove heterogeneous concentrations of heavy metals and chlorinated solvents, even under the most challenging site conditions.
How METAFIX® works
After the introduction of METAFIX® Reagents into the treatment zone, a series of physical and chemical processes create geochemical conditions under which common heavy metals are reduced, adsorbed, precipitated and converted into stable sulfide and iron sulfide precipitates.
The product is applied by direct push injection, mixing with the soil or hydraulic and pneumatic fracturing.
Key Benefits
- Ability to treat mixed contaminant plumes
- Low overall treatment costs
- No dependence on alkalinity for metal removal
