Assessment Of Physicochemical And Microbial Environment Of The Adi Ganga Stream

This study investigated the physicochemical and microbial properties of surface water collected from the Adi Ganga stream in Kolkata, India. Its analysis revealed several particularly concerning results. While the pH value was standard and pointed to balanced acidity, other parameters implied significant pollution. Abnormal and alarming values were found for conductivity, Total Dissolved Solids (TDS), Total Suspended Solids (TSS), Dissolved Oxygen (DO), and Biological Oxygen Demand (BOD), all of which were well outside the limits for water as recommended by the Central Pollution Control Board (CPCB) of the Government of India. The microbial colonies also had a high concentration, indicating bacterial contamination containing threatening amounts of pathogenic bacteria. The Chemical Oxygen Demand (COD), however, was unusually low, which may indicate a high concentration of non-oxidizable substances or an experimental error. The overall findings indicate that the Adi Ganga stream is heavily polluted, with a hypoxic environment and potentially dangerous bacteria.
