Abstract

The lower Pinios basin at the eastern coast of the Peloponnesus, hosts a system of alternative aquifers in the Pleistocene sediments of "Kalatha" formation. The elaboration of chemical analyses of the principal and trace elements of groundwater samples shown that a Redox environments and the presence of deep thermal water affect the groundwater quality. The aquifers sectors with reducing conditions are characterized by high concentrations of alkalinity, ammonia, total iron and total manganese groundwater. In the aquifers sectors with oxidizing conditions the values of the above parameters are low and the dominance of the chemical elements oxidizing forms are obvious.
