29. Hydrogeological conditions: The sanitary landfill of solid wastes must be carried out at a site where the hydrogeological conditions are such that the leachate infiltrates the soil and has a migration time of more than 5 years before it travels 300 metres or before it reaches a well or spring used as a source of potable water and situated at a distance of less than 300 metres, unless the leachate resurfaces within the given limits. In the latter case, it must have traveled in the soil more than 2 years at an average speed of less than 150 metres a year.
Where the hydrogeological conditions described in the first paragraph are not present, the sanitary landfilling may be carried out provided that measures are taken to prevent infiltration of the soil by all leachates. However, it is prohibited to develop a site with a view to carrying out sanitary landfilling if accidental infiltration would risk compromising the water quality of an aquifer utilized as a potable water supply.
Where the hydrogeological conditions of a sanitary landfill site are such that the water originating from that site surface or resurface before 2 years, a system permitting the complete containment and the treatment of such water must be installed in accordance with the requirements of section 30.
