Water pollution loads of river Büyük Menderes carried by Gümüşçay and Çürüksu within borders of Denizli

Abstract

It is aimed to determine the water quality and pollution parameters which are carried by Gümüşçay and Çürüksu Creek's to River Büyük Menderes (RBM). Cause and effect relations of measured parameters are investigated by SPSS 15.00 statistical software "Factor Analyze" approach. Temperature, pH, conductivity, salinity, total dissolved solid material, dissolved oxygen demand, chemical and biological oxygen demand values of water samples which are taken from designated measurement stations, are investigated in the light of Water Pollution and Management Regulation. Water samples taken from 6 different location of RBM, Çürüksu and Gümüşçay, are measured monthly throughout whole year. It is obtained that Gümüşçay and Çürüksu is 4th, RBM (about Sarayköy Bridge) is 3th class of water quality according to the organic matter concentration values. Total dissolved solid material vales of water samples shows that Çürüksu and RBM (about Sarayköy Bridge) is 2nd class of water quality. According to the results, 16 % salinity ratio of Çürüksu is due to Gümüşçay and approximately 70 % salinity ratio of RBM is due to waters mix from Çürüksu. Also 70 % of total dissolved material in RBM about Sarayköy is due to Çürüksu. The rate between flow values of Çürüksu before mix with RBM and flow values of Çürüksu after mix with RBM is approximately 57 %, although the rate of organic matter load value is 75 %. It is underlined that, the strategy development studies that will be done to rehabilitate the water quality of RBM could be start with the rehabilitation of water quality of Çürüksu.
