“…As a result of chemical and biochemical interaction between groundwater and contaminants from agricultural and industrial activities along with geological materials through which it flows (Bennetts et al, 2005;Gi-Tak et al, 2005), it contains a wide variety of dissolved inorganic chemical constituents in various concentrations. The characteristics of groundwater in different aquifers over space and time proved to be an important technique in solving different geochemical problems (Grassi and Cortecci, 2005;Adams et al, 2001;Alberto et al, 2001;Lopez-Chicano et al, 2001;Zanini et al, 2000;Atteia et al, 2006). Chemical ions correlation and some ions ratio are used to predict the origin of the mineralization (Pulido-Leboeuf et al, 2003;Gemici and Filiz, 2001;Liu et al, 2000).…”

The Maknassy basin is a typical example of an arid area in Central Tunisia. The geology of the area is mainly composed of Cretaceous calcareous formations. To identify the major process involved in controlling the groundwater chemistry, 53 groundwater samples for three different aquifer levels have been examined. The groundwater chemistry is dominated by SO 4 (Na þ Mg) and (Cl þ SO 4 ). The presence of (Ca þ Mg) and (Na þ K) with HCO 3 indicates the domination of dolomitic rock weathering as the major source of cations. The plots for Na to Cl indicate a fine correlation and reflects their release from halite dissolution during groundwater transition. An ion exchange process is also activated in study area which is indicated by a shift to the right in a plot for Ca þ Mg to SO 4 þ HCO 3 . The plot of Na À Cl to Ca þ Mg À (HCO 3 þ SO 4 ) confirms that Ca, Mg and Na concentrations in groundwater are derived from aquifer materials. Saturation indexes of groundwater samples indicate undersaturation for gypsum and anhydrite, and oversaturation for calcite, dolomite and aragonite confirming waterrock interactions by dissolution and dilution processes. In general, water chemistry is guided by weathering process, ion exchange and water -rock interaction during groundwater transition.

“…Hydrochemical analyses help to locate and quantify the mineralization of the water, provide information about the structure and dynamics of karst aquifer, and also help for understand the water-rock interactions. The physico-chemical characteristics of ground waters in karstic systems are determined by the lithology of the rocks which they cross, the physicchemical processes that predominate, the residence time of water and the various conditions and modes of circulation that coexist within them [3].…”

in the dry period of the year (5 anions and 11 cations). Water was sampled at three points: the first one at 30 m from the cave's entrance, the second one at 800 m from the cave's entrance, and the third one in the cave lake at 1000 m distance from the cave's entrance. Four methods (Piper diagram, Stiff diagram, Chadha diagram, and D'Amore diagram) were applied in order to determine the hydrochemical properties of the water samples. The results showed that all water samples have the same origin, all water samples belong to CaHCO 3 water type, water has temporary hardness, and the aquifer is composed of dolomite and limestone.

“…Discharge regime, water quality and parameters' fluctuation after precipitations are indicators of the state of the aquifer and the recharge area. 11,12 For this reason, karstic springs are an ideal measuring and analyzing location for the study of the entire karst system. 5 For geological features the Oliero springs are amongst the biggest karst springs in Europe, 13 with an annual average flow rate of 13 m 3 s À1 .…”

Chemical analyses of spring waters and factor analysis to monitor the functioning of a karstic system. The role of precipitations regimen and anthropic pressures

An approach is presented to study the functioning of a karstic massif and assess the adverse effects of the anthropogenic pressure by monitoring some water chemical and physical parameters of its main springs. The approach has been applied to the Sette Comuni Plateau (Veneto Region, Italy) hosting a well developed karstic system, whose aquifer presents high vulnerability and undergoes a relevant anthropogenic pressure. The Oliero springs, amongst the largest karstic springs in Europe, are the main water output of the plateau. Electrical conductivity, pH, dissolved O 2 , hardness, alkalinity, chemical oxygen demand, total suspended solids, ionic species (NH 4 + , NO 3 À , NO 2 À , PO 4 3À , SO 4 2À , Cl À , F À ), elements (Cr III , Cr VI , Mn, Fe, Ni, Cu, Zn, As, Cd, Hg, Pb), and some chlorinated solvents were monitored for one year. This study presents the application of a factor analysis on the water parameters enabling the identification of the dominant chemical and biological processes and pollution sources affecting the karstic system. Results show four factors which are interpreted as karstification, photosynthesis, storm flow pollution and anions. Finally, by associating metals, chemical oxygen demand and total suspended solids with the amount of rainfall in the 48 h before samplings, further detailed information to the fast response of the aquifer to precipitation events was detected and interpreted according to the factor analysis results. The proposed approach, by providing information on the functioning of the aquifer, may help the management of the karstic plateau and is easily adaptable to similar environments.
