Pagliarani V., Paolucci M., di Nauta S., 2012, Use of Oxidant Chemicals and Slow Release Oxygen Compounds for the Remediation of a Site Contaminated by Organic Compounds, Chemical Engineering Transactions, 28, 253-258.
Chemical oxidation is a remediation technology that allows to break down the main organic contaminants through oxidation carried out by chemicals that are harmless to the environment. This work describes the application of in-situ chemical oxidation (ISCO) technology in a case of typical hydrocarbon contamination in an active petrol station where setting up bulky remediation systems was not feasible. The injection of the oxidant compound into subsurface soil has decreased contamination within the soil matrix and the subsequent transfer of the reaction by product to groundwater makes its treatment easier. The significant observed improvement of groundwater quality parameters, such as redox potential and the dissolved oxygen, confirms the effectiveness of the applied treatment.
