In this study, 15 points for water samples and 20 points for soil samples were determined along the Çorlu Stream, which is an important branch of the Ergene Basin drainage network system, and some physicochemical and heavy metal analyses were performed by taking 3 samples from each point. According to Na+ (mg/l) value from water samples analysis, irrigation water quality class was determined as IV. class. In addition, irrigation water class of 6 sample points is classified as C3-S1 class. When evaluated in terms of heavy metal analysis results; Zn, Cu, Cr, As, Cd, Pb, Ni results as range of 65.7-198.8; 0.6-203.8; 6.5-69.4; 1.2-22.3; 0.1-0.3; 0.3-8.4; 9.3-57 μg/l was measured and no problems were observed in the evaluation. The analysis results of Fe and Mn elements was determined in the ranges of 587-8969.7 and 120.5-329.7 μg / l and it was observed that the Fe element exceeded the limit values at 2 points. According to heavy metal analysis results, Cu, Zn, Pb, Cd, Ni, Cr, Hg, Sn, Co and As values ranged from 3-20; 7-53; 14.8- 24.4; 0 to 0.1; 4.1 to 28.8; 9 to 200.9; 0.1-0.3; 0.3-2.5; 1.8-8.10.7-3 mg/kg, respectively. It has been determined that these results are below the permitted limit values according to the Regulation on Soil Pollution Control of the Ministry of Environment and Forestry. Ba element analysis results were measured as 135.5- 389.7 mg/kg and although it was seen to give results above the permitted limit values, no serious problem was determined according to the results of physicochemical analysis. According to the research results; It is necessary to act in accordance with the Water Pollution Control Regulation and the Soil Pollution Control Regulation of Ministry of Environment and Forestry in order to prevent the well-qualified and fertile soils of the Ergene basin and the water resources feeding this basin from being exposed to environmental pollution. In addition, breeding activities should be taken to continue the improvement works without delay and to make the necessary controls.
