Many years’ using of the non–classical geoelectric methods of forming short–pulsed electromagnetic field (FSPEF) and vertical electric–resonance sounding (VERS) for the varied problems of near–surface geophysics solving has shown the possibility of their application for the aquifers searching and contouring. The multiple experiments testify that areal survey by FSPEF methods allows to find and map operatively the zones of soils (rocks) moistening, the underground water flows of natural and man–caused origins and the aquifers. The bedding depths and thicknesses of water–saturated layers are defined in cross–section with high accuracy by VERS sounding. Works of such nature are carried out enough operatively and quickly. The preprocessing and interpretation of measurement data in field condition allows directly on place of the measurements undertaking to indicate the places of wells location. The FSPEF–VERS technologies efficiency is demonstrated by practical example of the optimum places determination for the water–supply wells locations.
