What is it about?
A study was conducted in order to understand the karst aquifer behaviour, recharge, and transport processes under low hydrological conditions. Results showed relatively low apparent dominant groundwater flow velocities. Multiple peaked and extended breakthrough curves suggest that contaminant transport may be lasting for several weeks and their concentrations may be increased after subsequent rainfall events. The delayed reappearance of the tracers suggests temporal storage in the aquifer.

Why is it important?
The findings obtained in this study have proven that simultaneous use of natural and artificial tracers is a valuable tool for studying complex karst systems and identifying alternating drainage areas due to changing hydrological conditions.
