『Abstract
　Sixty-one still bottled water samples, representing 41 locations, were collected from Hellas for the purpose of studying the geochemistry of ground water. Since, the dominating lithology comprises limestone, dolomitic limestone, marble, and mafic-ultramafic rocks (ophiolites), the dominant major ions in Hellenic bottled waters are Ca²⁺, Mg²⁺, CO3^2- and HCO3^-, and are, thus, classified in the Ca²⁺-Mg²⁺-HCO3^- hydrochemical facies. The source aquifers of Hellenic bottled water are apparently continuously replenished by fresh water. Comparison of values of Ca, Mg, K, Na, Cl^-, HCO3^- , NO3^-, SO4^2-, pH and electrical conductivity, displayed on bottle labels with those of this study, has shown that there is a fairly good correlation between the two data sets, suggesting that the geochemistry of source aquifers is relatively stable over time, at least from 1998 to 2008.
