Abstract :
The physical and chemical properties of the spring waters occuring in the area of the Athos (Aghion Oros) peninsula (N Greece) are studied in this paper. The geological and hydrogeological conditions prevailing in the study area are described. Two hundred springs were found in the study area. The majority of the springs have low to very low discharge. From the above springs fifty were chosen for sampling and hydrochemical analyses, on the basis of geological and hydrogeological criteria.
The studied spring waters are low TDS natural groundwaters. Their TDS values range from 113 mg/l to 620 mg/l. They issue from various aquifers and show characteristic differences concerning their chemical composition. The main factor that controls their chemistry is the mineralogical composition of the petrological formations (aquifers) occurring in this area. In the general these waters can be classified in two categories: a) "earthalkaline waters" and b) "earthalkaline waters with high alkaly concentration". The waters are mainly of bicarbonate- and bicarbonate-sulfate-type respectively.
The studied springs do not show any influence due to human activities. However, they show an indirect sea water influence. They have high Na+ and Cl- concentrations which are due to aerosols of sea water from the nearby sea. At the western coast of the peninsula occurs a mineral water spring (TDS = 9397 mg/kg) which belongs to the Na-Cl-mineralwater-type. This spring is strongly influenced by the sea water.
