In winter conditions, stormwater organic pollution caused by aircraft and runway deicing materials has been demonstrated on a number of French airports.

One of the main issues with stormwater management concerns the control of the organic pollution before discharge into aquatic environment and especially the knowledge of chemical and biological parameters which could improve degradation of deicing products. In this context, STAC has initiated in 2000, with the assistance of some laboratories, a first study dealing with the process of biodegradation deicing products used during Winter operations.

This work was extended in 2006 by an experimental study led on Bale-Mulhouse and Strasbourg airports.

All the results are presented in this document.
