ISOTOPIC AND CHEMICAL INVESTIGATION OF WATER SAMPLES IN ARGOLIS PENINSULA, GREECE

摘要

The area under study, located in the north-eastern part of Peloponnesus (Greece), is characterized by three major mountains (Arachnaio, Didima, Aderes), which constitute a complex orography and hydrogeology. Although the groundwater circulation in the peninsula is not very distinct due to the geological diversity, the objective of the study was to gain the fi rst regional picture of groundwater recharge in the area. Samples were collected from springs, wells and rain collectors and analyzed for environmental isotopes as well as major ions. The interpretation of the results was carried out in the light of other geological and hydrogeological information in order to determine the sources and mechanisms of recharge in the area. Arachnaio Mountain, which shows the highest altitude and extent, appears to be the main recharge zone which replenishes a number of springs in the peninsula.
