Abstract (EN): In hard rock terrains, down-the-hole hammer drilling is a method commonly used. Consequently, it is a destructive method, and the resulting drill cuttings are crushed rock and rock dust. A low-cost and valuable methodology to reconstruct the water well logs from drill cuttings is presented. That approach encompasses lithological, mineralogical, geo-structural, and hydrogeotechnical data. A comprehensive study of the site’s geology, engineering geology, and hydrogeology constraints supports the water wells design at an early stage. The cuttings were systematically collected and described during the drilling process, and they were registered hydrogeological field parameters for every 3 m drilled. The drill cutting samples were carefully described at the laboratory with a binocular microscope’s assistance. The design of the water well potentially intersects the fracture zone trending NNE-SSW. The groundwater flow seems to be associated preferentially with this orientation. That was confirmed in the drilling data and related to the productive groundwater zones. The synthesis and integration of this information allowed a significant improvement in the hydrogeological conceptual site model, thus contributing to efficient groundwater resource management.
