AB A tracer test during low-flow conditions was carried out in the karstic aquifer of Sierra de las Nieves(Málaga) in order to assess its hydrogeological functioning and vulnerability to contamination. Twokilogrammes of Eosine were injected in an active siphon located in the Sima del Aire cave shaft (-640 m)at the end of August 2003. The springs were sampled until November 2003. For more than 50 days, thetracer was not detected at any of the springs. After several rainfall events in October 2003, a signal wasobserved in the two Río Grande springs. The first arrival of Eosine appears before the increase of springdischarge and the dilution effect of the most important rainfalls (86 mm, October 25th). The calculatedgroundwater velocities (below 4 m/hour) are not representative of the dry period because rainfall forcedthe Eosine transport. However, they give an idea about the long residence time if a contamination eventoccurs during low-flow conditions
