A major problem of using of dyes for groundwater tracing is that it could be mixed with drinking water, which can cause a psychological shock in the local population when seeing appearance of luminous dye in their potable water. We demonstrated that measurements of spectra of fluorescence of natural waters (fig.1) and of uranine in dilutes from the activated charcoal detectors allow detection of uranine in concentrations below its visual detection threshold during dye tracing of underground waters.
