The hydrogeological conditions of a site are a key factor in selecting a productive aquifer for water-to-water heat pump systems, determining their optimal parameters, and assessing the impact of operation on natural processes and the environment. This study presents the results of a comprehensive investigation of the hydrogeological conditions at the experimental site of the Institute of Renewable Energy of the National Academy of Sciences of Ukraine. Based on geodetic measurements of surface elevations and analysis of drilling data, a hydrogeological cross-section of the site was constructed. It was determined that the Poltava aquifer is the most suitable for the application of heat pump technologies, and its main hydrogeological characteristics were defined. Long-term monitoring of groundwater temperature and level within the productive horizon allowed the determination of seasonal amplitude variations. Observations were conducted using a stationary automated monitoring system and a portable coil-type water level and temperature meter. Experimental data were processed in Surfer software to generate a formation pressure distribution map and identify the direction of groundwater flow. Test pumping and filtration experiments were used to construct an indicator curve showing the relationship between well discharge and drawdown, as well as to calculate the specific capacity of the well. The results indicate that the Poltava aquifer has relatively low filtration properties, making it more suitable for experimental studies and for partial coverage of the building’s thermal load at the Institute of Renewable Energy. The identified amplitudes of seasonal fluctuations in groundwater temperature and level should be considered when designing and operating groundwater-source heat pump systems.
