Abstract: In this work we present the use of the electronic nose EOS 835 (EN) for the screening of chlorinated substances into groundwater. Pollution of the groundwater to be analysed (Rho, Milan) reaches levels of contamination up to 0.1 g/l. The EOS835 is a tool equipped with a chamber with 6 different MOX sensors. It provided excellent results in terms of screening capabilities, in fact EN detected trichloroethylene in to the water up to 0.03 mg/ml. We can be concluded that the electronic nose could be used as a tool to assist the development of pollution remediation.
