HYDROGEOLOGICAL AND HYDROCHEMICAL INVESTIGATION OF DENIZLI MUNICIPALITY URBAN AREA

Abstract

Within the urban area of Denizli Municipality and its vicinity, the hydraulic picture is a combination of three aquifer systems in the (a) alluvium (b) alluvial fan and (c) the Neogene lacustrine deposits. At different locations free surface, semi-confined and confined aquifers are observed. These aquifers are recharged by rain water and groundwater flow coming from the metamorphic rocks located at the southern parts of the study area. The groundwater exploitation potential (artesian and pumping) is high. The total ion concentration in the groundwater increases in the flow direction. At the same time, the chemical composition changes from calcium bicarbonate to magnesium sulfate type. This is due to the solution of the salts in the Neogene sediment deposits which get in contact with the groundwater. This brackish groundwater is not potable.
