Abstract
Airport surface runoff during winter time contains high concentrations of pavement de-icing fluids. Uncontrolled discharge of this runoff poses a potential environmental hazard for the terrestrial and aquatic ecosystem. One possibility is a soil based filter to treat the contaminated surface runoff. The main goal is to determine the capability of the in-situ soil and a soil based filter using structural filter materials to degrade the organic pollutants. Based on previous results, the use of a soil based filter shows to be a promising, passive, natural based solution for the treatment of de-icing runoff. This should now be verified in small areas in-situ at an airport.
