24. Owners of spring water, mineral water or groundwater catchment sites supplying more than 20 persons must take the measures necessary to maintain the quality of groundwater, in particular by delimiting an immediate protection area established within a radius not less than 30 m from the catchment work. That area may be smaller if a hydrogeological study signed by an engineer who is a member of the Ordre des ingénieurs du Québec or a geologist who is a member of the Ordre des géologues du Québec shows the presence of a natural protection barrier, such as the presence of a layer of clay.
For the purposes of this Regulation, “spring water” and “mineral water” have the meaning assigned by the Regulation respecting bottled water (chapter P-29, r. 2).
A safety fence at least 1.8 m high must be installed at the boundaries of the immediate protection area of a catchment site the average flow rate of which is greater than 75 m3 per day. A notice must be posted at the catchment site and indicate the presence of a groundwater source intended to supply water for human consumption.
Within the immediate protection area, activities, facilities or deposits of materials or objects likely to contaminate groundwater are prohibited, except equipment necessary to operate a catchment work when installed safely.
The finishing grade, within the immediate protection area, must be carried out so as to prevent the infiltration of water.
