Abstract: | The hydrochemical response at springs in the drainage area of the Sierra del Rey—Los Tajos carbonate aquifer (province of
Málaga, southern Spain) was monitored in order to determine the hydrogeological functioning of this aquifer. Analysis of the
most important chemical parameters, using methodologies such as the temporal evolution of chemical components, principal component
analysis and discriminant factorial analysis revealed that the high level of hydrochemical heterogeneity to be found in this
discharge zone, in addition to particular spatial and temporal factors, is responsible for the mineralisation of the spring
water. Sampling in karst systems where discharge occurs by several springs should take into account the hydrochemical variability
of them; otherwise conclusions about the hydrological functioning of aquifers deduced from mixture of spring waters can be
inaccurate. |
