One of the crucial environmental problems through the world is the pollution of groundwater by run-off and snowmelt from roads. In the case of incorrect environment protection in the vicinity of roads the pollutans may migrate to groundwater causing hazard to sources of potable water. Imposing the flow of polluted water through a reactive materials filling a multilayer permeable reactive barrier (PRB) is one of the methods to prevent pollutans to groundwater. This paper focus on composition of road run-off samples (water in spring and summer, snow in winter) collected along road network in Warsaw. Moreover, the ability of the zeolite, activated carbon, zero-valent iron and geza rock to immobilize the contaminant sources from de-icing agents is also included. Finally, the analyses of the influence of chemical substances (chloride and lead) on the hydraulic properties of activated carbon (the most suitable reactive material) have been made in adjusted triaxal test equipment. Based on the laboratory test results the general conclusions related to the ability of a reactive materials tested for application in the multilayer PRBs were drawn.
