The document was prepared by Mr. Durand, a retired UQAM professor and geologist, who is concerned about these risks. There are other risks associated with transportation, spills and obviously wastewater treatment, given that 50% of the water used and removed from the ground must be treated after the fracturing process.
Il y a d'autres risques en ce qui concerne le transport et les déversements, et il y a évidemment la question du traitement des eaux usées, puisqu'il faut traiter 50 p. 100 de l'eau utilisée qui est sortie de terre après la fracturation.
