A system for mapping a depth of an aquifer and determining the presence and salinity of water from the aquifer and methods for using the making/using the same includes a central processor. One or more horizontal loop transmitters can be coupled to the central processor, wherein said one or more horizontal loop transmitters produce a first half-sine pulse of magnetic field at a first pulse duration for measuring the resistivity of a ground surface. The one or more horizontal loop transmitters can produce a second sequence of half-sine pulses at a second frequency for creating an excitation field for magnetic resonance sounding. A multi-turn receiver loop antenna can also be coupled to the central processor, wherein said multi-turn receiver loop antenna receives an induced magnetic field from said one or more horizontal loop transmitters that is representative of the depth of an aquifer and the salinity of the water.
