Monitoring of thermal waters in Croatia - the chemical and quantity aspect: case study NW Croatia

Due to favourable geological conditions, the greatest geothermal potential in Croatia exists in the Pannonian part of the country, with numerous thermal phenomena. The use of thermal aquifers in Croatia is defined by the legislative framework, under which the state requires that the user manages the geothermal resource sustainably. If thermal aquifers are used for balneological, recreational, medical purposes, or bottled and placed on the market, then the management of the use of these resources is according to the Water Act (OG 66/19, 84/21). However, if they are used for energy purposes (for the production of electricity and/or heating), then the management of the use of these resources is according to the Act on Exploration and Exploitation of Hydrocarbons (OG 52/18, 52/19, 30/21). Both acts and their rulebooks do not require obligatory monthly or annual monitoring of chemical parameters and groundwater levels/or yields. The only demands are to monitor the daily amounts of pumped water and thermal wastewater (released in the nature or sewage system). As a consequence, there is lack of systematic data on chemical parameters and groundwater levels/ or yields for utilized locations. However, during the DARLINGe and RER7013 projects in period from 2018 till today, monitoring of chemical and isotope parameters, and groundwater levels/or yields were established in selected springs and boreholes in the NW part of Croatia. The selected thermal locations are: B-1 borehole (Stubičke Toplice), Jez-1 (Jezerčica), Vrelo u Bari spring (Tuheljske Toplice), Pučka and Jakobova kupelj springs (Krapinske Toplice), B-1 borehole (Varaždinske Toplice), Vuč-2 borehole (Toplice Sv. Martin na Muri), Mla-3 and KBNZ-1A boreholes (Zagreb). Sampling frequency varied from one to three months. After recent earthquake events (March 2020, Zagreb and December 2020, Petrinja), several locations of thermal waters experienced changes in both chemical and quantitative status. Currently, there is draft of Water management plan for 2022- 2027, published in January 2022, which will regulate to establish monitoring of mineral and thermal waters.
