Comparative Analysis of Water Quality in Dam Lakes of Edirne Province, Türkiye

Özet

Edirne Province is located in the northwestern part of Türkiye's Marmara Region. This area is classified as "Agricultural Land" because of its abundant freshwater resources and fertile soils. In the current research, the water qualities of Sultanköy and Altınyazı dam lakes were assessed and compared. Water samples were taken from the reservoir outlets in the autumn of 2024. A total of 12 physicochemical parameters were measured, including dissolved oxygen (DO), electrical conductivity (EC), pH, total dissolved solids (TDS), turbidity (Tur), salinity (Sal), suspended solids (SS), nitrite-nitrogen (NO₂-N), phosphate-phosphorus (PO₄-P), nitrate-nitrogen (NO₃-N), sulphate (SO₄), and ammonium-nitrogen (NH₄-N) using a multi-parameter meter and a spectrophotometer. The results of the study indicated that the water quality in both dam lakes was comparable, with both reservoirs demonstrating first-class water quality for DO, pH, NO₃-N, and NH₄-N parameters, second-class water quality for EC and NO₂-N parameters, and third-class water quality for PO₄-P.
