Monitoring of Road Deicers in a Retention Pond
Résumé
In winter maintenance, the application of road de-icing products on transport infrastructures is a common practice for road security. However, these products are transported from the roads into the surrounding environment by numerous factors (rain, wind, traffic, ...). The importance of monitoring their dissemination in the environment is demonstrated by the investigation of a retention pond used for the road water treatment. Sodium and chloride concentrations were monitored during the winter 2012/2013 in the inlet and outlet waters of a retention pond. The impact of meteorological data and salting operations on the concentrations measured are investigated and the implications of encountered concentrations discussed.
