ABSTRACT
The artificial tracers tests can provide very useful information in applied hydrogeological researches, but potential pollutant effects must be taken in into consideration. To avoid such problems, two fluorescent dyes (Leucophor BCF and Tinopal CBS-X) were tested in laboratory and experimental fields and then used in different aquifers (karst, fractured, porous) with focus on various issues: location of protection areas, detailed flow identification for pollution problems, testing well cementation, average flow rate for engineering projects, calculation of kinematic porosity, estabilishing the relationship between surface and ground waters. In spite of some problems due to low detectability, high photosensivity and lack of data on tracers’transfer speed related to aquifer flow rate, these substances are useful and well suited for hydrogeological research.
