The paper presents the assessment of utilizing Quaternary groundwater in low-temperature geothermal systems based on the example of intake 1/828/3 Zawoja-3, located in the south-western part of the Małopolska Province. Based on the data on the water yield and water temperature, the thermal power potential of the water intake as the lower source for the heat pump was estimated. Using the empirical formula method and the relevant requirements indicated by manufacturers of heat pumps, the assessment of the groundwater quality of the Zawoja-3 intake with reference to its potential of scale formation and corrosivity were made (based on the 2000-2014 water analysis from the groundwater monitoring database). Moreover, the assessment of the stability ofphysical and chemical parameters indicated by manufacturers of heat pumps as beingimportant for the proper operation of installations was presented. The analysis has shown that the Zawoja-3 intake has a potential to utilizeQuaternary groundwater in low-temperature geothermal systems. However, for the safe and long-term operation of the system, it is recommended to use an intermediate heat exchanger before the heat pump.

The paper presents the possibilities of utilization of Quaternary groundwater in low-temperature geothermal systems in Małopolska. Water as a heat source must fulfill the relevant requirements for physicochemical parameters. In this paper, physicochemical parameters of water used in low temperature systems: pH, electrical conductivity, chloride, sulphate, oxygen, iron and manganese have been evaluated. Data for this study were obtained from the Polish Hydrogeological Survey (PSH is carried out by the Polish Geological Institute – National Research Institute). The analysis showed that Małopolska has potential to use Quaternary groundwater in low temperature systems.
