Analysis of the Status of Surface Waters in the Sącz Agglomeration Based on Physicochemical Parameter Studies

The analysis of the quality status of surface waters, carried out through two series of raw-water sampling at nine designated points during the astronomical summer and autumn, aims to assess the water quality of the rivers: Poprad, Kamienica, Dunajec, and the Łubinka stream. The study aims to determine the water purity class of the examined rivers in accordance with applicable legal standards. Raw water samples were analyzed in an accredited laboratory to determine selected physicochemical parameters. The analysis showed increased concentrations of both physical (e.g., suspended solids) and chemical (e.g., heavy metals) parameters. The study did not reveal analyzed pesticide levels high enough to be detected by laboratory instruments at nine sampling points marked as: P1, P2, K1, K2, Ł1, Ł2, D1, D2, D3. The most important factors influencing the quality of surface waters in the studied area are primarily the proximity. The most important factors influencing the quality of water in the Sądecki agglomeration include the proximity of watercourses to agricultural fields where fertilizers are used, as well as to wastewater treatment plants, landfills, and industrial facilities.
