32. It is prohibited to construct a drilling site or conduct a stratigraphic survey in a floodplain having a flood recurrence interval of 20 years, in the identified floodplain of a lake or watercourse unless the 20-year and 100-year flood recurrence intervals have been distinguished or less than 500 m from a site where water is withdrawn for human consumption or food processing.
The distance of 500 m provided for in the first paragraph concerning the construction of a drilling site may be increased to the distance set in the hydrogeological study provided for in section 38 where the study shows that the distance of 500 m does not minimize risks of contamination of the sites where water is withdrawn for human consumption or food processing that are located on the territory covered by the study.
