This study presents a comparative analysis of water quality parameters in urban sites, focusing on the Surma and Kushiyara rivers in Bangladesh. Water samples collected from 2010 to 2013 during rainy and winter seasons were analyzed for key parameters including temperature, pH, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Solids (TS), Total Dissolved Solids (TDS), and Suspended Solids (SS). Statistical tests, including Independent Sample t-test and Paired t-test, were employed to evaluate differences between the two rivers. By paired t test, it is found that statistically significant difference exists between temperature, DO, TS and TDS in rainy and winter seasons for the Surma river. For the Kushiyara river, temperature, pH, DO, TS, TDS and SS showed statistically significant difference among rainy and winter seasons. The independent t test among the Surma and the Kushiyara rivers water quality parameters, revealed that only temperature of winter seasons showed statistically significant difference, but all other water quality parameters showed statistically no significant difference between them.
