Water quality is a substantial measure in coordinating water demand and supply. An adequate level of freshwater is eminent for biological needs and a vital side of integrated sustainable environmental development. There has been a disrupting ascend in the water pollution due to the natural and anthropogenic events. Past few years, research has enormously engrossed on the development of water quality index (WQI), as a prevalent tool for water quality assessment. This review article presented an in-depth literature-based look up of WQI's potentials concerning their use as a scientific tool for river water quality monitoring and management. This study also highlighted the importance, limitations and future directions of WQI tool to afford additional information about its usage. The review indicated the influence of the environmental features, like geographic locations and sampling periods, on the estimation of WQI. Also, WQI was projected as a single value which decreased the immense amount of water quality parameters and epitomized the data in a simple way. The incessant use of WQI tool provided long-term information for helping the water resource managers, environmental engineers and scientists in decision making and management.

水质是协调用水需求和供应的一项重要措施。满足生物需求和综合可持续环境发展的重要方面即将达到足够水平的淡水。由于自然和人为原因，水污染的上升趋势受到破坏。在过去的几年中，作为水质评估的主要工具，水质指数（WQI）的开发投入了大量精力。这篇综述文章对WQI的潜力进行了深入的文献研究，有关WQI的潜力，这些潜力被用作河流水质监测和管理的科学工具。这项研究还强调了WQI工具的重要性，局限性和未来发展方向，以提供有关其使用情况的更多信息。审查指出了环境特征的影响，例如地理位置和采样周期，取决于WQI的估算。而且，WQI被投影为一个单一值，这可以减少大量水质参数并以一种简单的方式概括数据。不断使用WQI工具可提供长期信息，以帮助水资源管理者，环境工程师和科学家进行决策和管理。
