Historic leakages at an active manufacturing facility in Northern Italy resulted in the underlying groundwater becoming impacted with hexavalent chromium (Cr(VI)) contamination of up to 2,000 μg/L, and chlorinated solvents (CHC) concentrations of up to 10,000 μg/L. 3-D Microemulsion® (3DMe) and Metals Remediation Compound (MRC®) were selected to remediate the site because of:

• The combination of products allow for effective distribution and treatment within a highly heterogeneous and deep aquifer comprising gravels and boulders;
• Minimal disturbance caused by in situ remediation activities and the ability to inject indoors, on this tight and busy site.
