Abstract

The health resort Duszniki-Zdroj is located in the south-western part of Poland in the Sudety Mountains. The southern part of the city ? the Spa area ? contains medicinal waters intakes. What is interesting, all of them are flowing wells. The spa part of Duszniki Zdroj is located at the northern edge of the Orlica-Bystrzyca Metamorphic Complex. At present, there are nine boreholes with medicinal waters, three of which are exploited. The total discharge from these intakes is 31.96 m3/year. The mean discharge over multiple years has oscillated from 3.95 m3/h (Jan Kazimierz) to 16.53 m3/h (Pieniawa Chopina). The results of exploitation observations have demonstrated that the significant content of the gas (CO2) in water affects the variability in intake discharge. The major ions determining the chemical composition of these waters are HCO3- ions (86% meq to 100% meq) and calcium ion (34% meq to about 70% meq) and the waters represent Ca-Na(-Mg)-HCO3 type. The mineralization of waters varies from 0.5 to about 3.9 g/dm3, and their pH ranges from 5.2 to 7.0. The temperature of waters at the outflow is much higher than the average annual air temperature in this area (7.0°C) and varies from 10 to 18.8°C, while in the GT-1 borehole it is about 35°C.
