Objective: A simple comparative study of evaluation of biochemical oxygen demand (BOD) of river water of Ganga’s has been developed with statistical analysis between far water and near water. Material and Methods: The process has been conducted by simple titrimetric method by taking four 200 ml BOD bottles (two for sample & two for blank) and analysed two different intervals in the gap between five days. The total process was repeated for four times times, one for near water & another for far water. Results: Far water BOD value came less than near water BOD value as the experiment have been performed. Conclusion: So it can be concluded that far water system in more compatible for aquatic life.
