In-situ Chemical Oxidation (ISCO) is a particularly interesting option for the remediation of contaminated sites. Our research group has gathered considerable experience over recent years in comprehending the fundamental phenomena underlying chemical oxidation processes and developing a methodology for designing interventions based on both numerical and experimental modelling. This methodology entails at first the execution of laboratory scale experiments for the selection of the oxidant and the best operating conditions. On the basis of these data and site specific information, the layout of the intervention is defined through numerical modelling. The data thus gathered can be subsequently verified through another step of experimental modelling, carried out with a bench-scale column plant equipped with instruments for measuring different process parameters. The tests that have been carried out have led to the pilot scale design of some interventions based on the use of Fenton's reactive, which shall be employed for the elaboration of an ISCO application protocol which will integrate the protocol published by ISPRA in 2005.
