- The remediation of CrVI using 3-D Microemulsion allowed for effective source treatment and plume control, even under complex hydrogeologic and site-access conditions
- 3-D Microemulsion not only met cleanup objectives onsite but significantly reduced risk offsite to acceptable levels as well
- No need for repeat injections or additional infrastructure, redevelopment could proceed without delay
In a town in Spain’s Basque Country, a former cutlery manufacturing site contaminated with hexavalent chromium (CrVI, Cr6) was slated for redevelopment into retail use. High CrVI concentrations in the groundwater—originating from historic plating operations—posed a significant risk to a nearby river. A targeted in situ remediation strategy using 3-D Microemulsion® was implemented to address both source and plume areas. Pilot testing demonstrated rapid and far-reaching reductions in CrVI levels, enabling a streamlined full-scale design. The project achieved the site-specific remediation targets cost-effectively, including offsite improvements, without requiring repeat injections or extensive infrastructure. The property has since been sold and is now under active redevelopment.
