Water is the basic need of every living form including plants, animals, human, and microorganisms. Recent unplanned industrialization, rapid urbanization, and destruction of water resources, including the use of them as waste dumping grounds, deforestation, and depletion of water resources, have all played a role in the deterioration of aquatic environment on the earth. The Water Quality Index makes it easier to communicate knowledge about water quality patterns to the general public, policymakers, and water quality managers by simplifying the understanding of various physicochemical parameters. In the present study, Nemerow’s Pollution Index (NPI) was used to assess the water quality of Vashi Creek using Indian Council of Medical Research and BIS standards. Data from 2008 to 2019 of Vashi Creek was extracted from the publically available database of the "ENVIS Centre on Control of Pollution Water, Air, and Noise". The extracted data was analyzed for water physicochemical parameters as well as NPI water quality analysis. NPI water quality analysis revealed that conductivity and BOD both exceeded the acceptable limit.
