Water is a strategic resource for every country. In recent years, the level of pollution in many water bodies has increased significantly. Military operations on the territory of Ukraine have caused great damage to natural resources. To identify possible sources of water supply, it is necessary to monitor the water quality of natural water bodies. Water samples from six forest springs located a short distance from the city of Przemyslany were taken at different times of the year. The water in all samples is clear, without turbidity or color, and odorless at 20°C and 60°C. The total water mineralization, pH, and nitrate content were measured. The water hardness, calcium and magnesium content were determined by the complexometric titration method. The study of physical and chemical indicators of water quality of forest springs shows small changes in the studied parameters during the year in five out of six forest springs. The obtained values do not exceed the standards established for drinking water. In the water samples of source No. 6, the nitrate content and total water hardness are high, although they do not exceed the permissible standard values. Significant fluctuations in the nitrate content of water samples from source No. 6 were found throughout the year. The use of such water for drinking and production needs may have a potentially harmful effect. The water of the studied springs requires further research and can be considered as an alternative source of water supply.
