Pollution in storm water runoff in a highway toll gate area and performance of a source-area treatment technology

S. Papiri, C. Ciaponi, S. Todeschini & P. Valcher
This report describes the experimental equipment and the first results of a study to characterise the quality of storm water runoff in the area of a medium traffic flow highway toll gate and also to evaluate the efficiency, for this type of surface, of a \342\200\234source-area treatment\342\200\235 technology currently on the market called EcoDrainTM. This system was designed to reduce pollutants carried into storm drains by water runoff via filtration and absorption. The report presents...
