In the framework of a monitoring program to investigate water quality constituents associated with stormwater runoff subject to urban land use and activities, a monitoring station was installed within the airport of Genoa (Italy). Water quality data indicate a significant mass delivery of dissolved metals (mainly zinc) while limited concentration values of both particulate and organic matter were measured. A mass limited behaviour was generally observed for the wash-off process of the particulate matter (measured as TSS) and TOC, while the mass delivery of aqueous metal species was more proportionate to the runoff volume. The delivery behaviour of dominant species for aqueous metals (zinc, copper and lead) was examined using water quality analyses, ion balances and speciation modelling.

Abstract
In the framework of a monitoring program to investigate water quality constituents associated with stormwater runoff subject to urban land use and activities, a monitoring station was installed within the airport of Genoa (Italy). Water quality data indicate a significant mass delivery of dissolved metals (mainly zinc) while limited concentration values of both particulate and organic matter were measured. A mass limited behaviour was generally observed for the wash-off process of the particulate matter (measured as TSS) and TOC, while the mass delivery of aqueous metal species was more proportionate to the runoff volume. The delivery behaviour of dominant species for aqueous metals (zinc, copper and lead) was examined using water quality analyses, ion balances and speciation modelling.
