Seasonal variation in water quality of River Vishwamitri with reference to physico-chemical parameters

Abstract

River Vishwamitri at Vadodara was studied for physico-chemical parameters at four sites for summer and monsoon seasons in the year 2011. The correlation between various water quality analysis was performed. In summer, pH, EC, TDS, TSS, Turbidity and BOD showed positive correlation with temperature and negative correlation with COD, Chloride and hardness. In monsoon, TDS, EC, Turbidity, BOD, COD, Chloride and Hardness showed positive correlation with temperature and negative correlation with pH and TDS. The undesirable changes in the river quality parameters suggested that the river is highly polluted as it is used as a sewer collector.
