The aim of this study is to describe the first full scale application of a zerovalent iron permeable reactive barrier in Italy. The PRB was designed and realized to remediate a chlorinated hydrocarbons plume at an old industrial landfill site, in Avigliana, near the city of Torino, in the Piemonte Region.

Abstract

The aim of this study is to describe the first full scale application of a zerovalent iron permeable reactive barrier in Italy. The PRB was designed and realized to remediate a chlorinated hydrocarbons plume at an old industrial landfill site, in Avigliana, near the city of Torino, in the Piemonte Region. The dimensioning of the PRB was conducted by means of a three dimensional flux and multispecies contaminant transport model based on column degradation test. The excavation of the 120 m long, 13 m deep and 0.6 m thick barrier, was performed in just 8 days using a crawler crane equipped with an hydraulic grab and supported by guar gum slurry. After the excavation, the trench was backfilled with 1700 t of iron and the biopolymer degraded using enzymes. The final configuration of the site will be characterized by a wide car park, a ciclo-cross track and a green capping to prevent the infiltration of water from the ground surface to the shallow aquifer.
