132. The hydrogeological study must contain the following documents:(1) a map at a scale of 1:20 000 showing the location of all the wells or sources of drinking water, as well as any natural reservoirs of drinking water within a radius of 2 km;
(2) a geological map illustrating the rock outcrops and the units of unconsolidated deposits within a radius of 1 km;
(3) a description of the local hydrography, geology and hydrogeology;
(4) a map of the zone studied showing the location of stratigraphic drill holes at a scale between 1:2 000 and 1:5 000;
(5) geological sections of the drill holes;
(6) the results and conclusions of in-situ and laboratory tests and the calculation methods used;
(7) a piezometric map of the sector concerned at a scale between 1:2 000 and 1:5 000;
(8) the results of water analysis and a siting proposal for the reference well and the observation wells; and
(9) a hydrogeological report establishing that the land complies with the hydrogeological standards set out in sections 100 to 102, the quality and extent of the current and potential use of groundwater and the vulnerability of groundwater to pollution.
