Abstract : The current investigation studies the physiochemical parameters and level of organic contamination of water samples obtained from four main creeks of Western Coastal region of Mumbai – Malad creek, Vasai creek, Mahim creek, and Manori creek. The analysis was carried out for such parameters as hardness, salinity, acidity, Chemical Oxygen Demand (COD), and Biological Oxygen Demand (BOD). Based on the analysis results, significant differences were found regarding the location of the sampled water bodies. Vasai creek displayed the maximum salinity level (15940 ppm) and hardness because of strong tidal influence and high content of dissolved ions in water. Mahim creek indicated the highest acidity (229.68 ppm) due to severe human interference into the environment of this creek. All analyzed creeks demonstrated the high COD level that ranged between 512 and 864 mg/l. This means that high level of organic pollution was observed at these water bodies. Strong connection between COD and BOD confirms the high amount of biodegradable organic pollutants.
