An Investigation of the Road Salt Phytoremediation Possibilities in France

Between 800,000 and 2,000,000 tons of road salt are applied each year on the French roads. Due to weather conditions and traffic, they are transported out of the roads. Hence, large quantities end up either in the surrounding environment or in ponds used for road runoff remediation and flow control. However, these ponds are not designed for the treatment of salt, despite its adverse environmental impacts. After passing through the ponds, salt is then rejected into the environment. To diminish the quantities thus rejected, a specific depollution solution needs to be developed.
