9. reground aims at restoring contaminated groundwater aquifers
by developing a novel technology for the injection of iron oxide nanoparticles into groundwater contaminant plumes. This project addresses mainly arsenic and the known major groundwater contaminants (barium, cadmium, chromium, copper, lead, mercury, nickel, zinc).
Iron oxide nanoparticles are injected to form an in situ barrier for the immobilization of heavy metal contaminations in ground water

10. Injection Site: Barreiro (Portugal)

11. Heavy Metal Contamination in Barreiro
Research Goals:
Large Sacle Production (2 field sites)
Mobility & Reactivity (stability including long term stability, adsorption capacity)
Toxicology (environmental impacts)
Dissimination (business plan)
Market Ready Product
