Construction and monitoring of a permeable reactive barrier near the city of Torino in Italy

The aim of this study is to describe the first full scale application of a zerovalent iron permeable reactive barrier in Italy and illustrate the preliminary results of the monitoring plan. The PRB was designed and emplaced to remediate a chlorinated hydrocarbons plume at an old industrial landfill site, in Avigliana, near the city of Torino, in the Piemonte region. The installation of the 120 m long, 13 m deep and 0.6 m thick barrier was accomplshed using a clamshell for the excavation of the trench and a guar gum slurry to support the walls. After a description of the intervention, preliminary results of the monitoring plan are presente
