Geotextiles are fibrous materials increasingly employed for the design of infiltration basins to separate different materials and for their hydraulic properties (drainage). Though currently used, their effect on the transfer of contaminants carried by stormwater has not been fully investigated. This study aims at showing that this effect depends upon contaminant load. Leaching column experiments were subjected to high metallic load and compared to previous leaching experiments at low load . In the new columns, the metallic load was sufficient to allow SEM observations and provide useful information on their filtering contaminated particles.
