Abstract The water quality index (WQI) model is a popular tool for evaluating surface quality. It uses aggregation techniques that allow conversion of extensive data into single value or index. Globally, the WQI has been applied to evaluate (surface and groundwater) based on local criteria. Since its development in 1960s, it become due generalised structure ease-of-use. Commonly, models involve...
