Determination of Surface Water Quality in Susurluk Stream (Balıkesir-Turkey)

The Susurluk Stream is under the threat of pollution due to population growth, industrialization and agricultural activities. Therefore, it was aimed to determine some water quality parameters of the stream (temperature, pH, dissolved oxygen, total dissolved substance, conductivity, anionic detergent, phosphate, boron, copper, chromium, nickel and lead). The average values were found as follows; temperature 17.5 °C, pH 7.9, dissolved oxygen 6.01 mg/L, total dissolved substance 395 mg/L, conductivity 788 µS/cm, anionic detergent 0.297 mg/L; phosphate 0.039 mg P/L; boron 0.921 mg/L; copper 1.954 µg/L; chromium 0.375 µg/L; nickel 2.230 µg/L; lead 0.175 µg/L. These values were compared with the criteria values specified in the relevant regulations and the quality of the water was determined.
