Hydrochemical Assessment of the Aquifer of Thermal Waters in Llixha, Elbasan, Using Stiff Diagrams

Abstract

The Elbasani region is characterized by its strong hydrodynamics regime, which comes from the powerful movements of underground water combined with many resources; therefore, the area has geothermal potential, and is one of the most popularly used in our country. This area has a number of sources, located in the form of a chain in the sector between Llixha and Hidrajt, and constitutes a thermomineral basin with a stable discharge and high temperature, at the upper limits of low enthalpy, reaching above 60 °C. The current average flow of thermal water is about 15–18 L/s and temperatures vary from 55 to 65 °C. It is estimated that these resources have specific reserves of 39.6 GJ/m2 and the potential to install 2760 kW of power. To evaluate their basic physico-chemical parameters and nutrients, water samples were taken throughout 2022 at five monitoring stations, covering the entire aquifer. Stiff diagrams have been used to explain the similarities between the physico-chemical properties.
