• Successful groundwater treatment for TAUW in a church oratory garden in Italy
• PCE reduced to below regulatory target without any VC build-up, resulting in No Further Action (NFA)
• Simultaneous remediation using advanced colloidal technologies enhanced the chemical degradation and sorption processes, optimizing treatment efficacy.

A permeable reactive barrier for in situ groundwater plume treatment, implemented in a church oratory garden, has achieved No Further Action (NFA) status as part of a broader initiative to address groundwater contamination from tetrachloroethene (PCE) at a manufacturing plant in Italy. Using a combination of S-MicroZVI® and PlumeStop®, the project successfully reduced PCE concentrations below the target level of 100 µg/L, with consistent results observed over multiple years of bi-monthly monitoring.
