The electromagnetic transmitting system is at an upstream point and includes a generator and a transmitter having a capacitor; the transmitting antenna penetrates into a detected aquifer through karst collapse or a drill hole; the electrodes and the receiver are at a downstream point, and include two pairs of electrodes orthogonally distributed and located in a cofferdam formed by downstream water; and the receivers collect electric signals in the electrodes. The apparatus is based on good electrical conductivity of water, and can use electromagnetic signals as a tracer for rapid observation. Compared with traditional tracers, electromagnetic signals propagate fast in water, are stable in property, and free of pollution. This apparatus can be applied to groundwater tracing detection, and problems with the traditional tracers having poor timeliness and being environmentally unfriendly are resolved.
