Water is essential for the proper functioning of humans, animals and plants. The existence of humans and animals is not possible without water. Water is used for various purposes such as agriculture, industry, power generation, entertainment, domestic use and drinking. Due to the industrialization and urbanization water pollution occurred on a large scale. Polluted water is not useful for drinking purposes. Recently water is getting polluted everywhere, the incidence of water-borne diseases has increased, so there is a need to assess the quality of water and check the proportion of pollution in the reservoirs. "Water quality is the proper physical, chemical and biological properties of water." The present research has been conducted on the assessment of drinking water quality using water quality index (WQI) method, applied to a local dam serving Satana city in Maharashtra. This research is high relevance due to growing concerns over water pollution and its impact on public health. By assessing physical, chemical, and biological parameters the study attempts to highlight the usability of dam water for human consumption and other uses. For this study Water sample taken from Punad Dam and tested various parameter in laboratory. The water quality parameters included are the concentration of pH, Total Dissolved Solids (TDS), Calcium, Magnesium and Turbidity. Water quality index (WQI) is a mathematical tool used to assess water quality on various parameters, this method helps assessing the overall water quality basis on the parameters. The water quality index of Punad dam is 12.49 is excellent for human consumption and other uses.
