Comparison between different approaches for the definition of soil contamination indicators of stormwater infiltration systems

摘要: The use of infiltration systems to manage stormwater is becoming widespread in French urban areas. Dry infiltration basins are the most popular form. Despite their advantages, their long-term sustainability is often questioned. Over time, two major problems are encountered: clogging and potential contamination of the soil and groundwater systems. To evaluate soil contamination and the groundwater contamination, indicators turned out to be interesting tools. To define such indicators two approaches were proposed: one is based on conventional pollution physicochemical characteristics, and the other on ecotoxicological tests.
