Q-2, r. 18 - Regulation respecting the burial of contaminated soils

Full text
12. Contaminated soil burial sites must be equipped with a system that collects all the leachates and conveys them towards a treatment unit or a leakproof reservoir sheltered from water from precipitation, and that enables the quality of the leachates to be determined before discharge.
“Leachate” means any liquid or filtrate that has percolated through the contaminated soils.
For the purposes of the first paragraph, a leachate collection system must be installed on the sideslopes and bed of the burial site over the impermeable membrane. The system must be designed so that the maximum height of the liquid likely to accumulate on the bed of the burial site may not be greater than 30 cm.
Another system to collect and discharge leachates, intended to detect leakage, must be laid out between the 2 impermeable membranes. The layout of the collection system must allow for monitoring separate from the other collection systems.
