Introduction: Over the past century, water scarcity has become a significant global issue due to climate change, population growth, urbanization, and agriculture. In response to this problem, groundwater resources have been used extensively for various purposes, including agriculture, industry, and drinking. However, the increasing global demand for water has led to the overexploitation of groundwater and a decline in quality. Groundwater pollution has adversely affected the accessibility and suitability of groundwater and is detrimental to human health. Furthermore, cleaning up polluted groundwater is costly and time-consuming due to the complex nature of groundwater systems and the invisible threat of groundwater contamination. Therefore, assessing and monitoring groundwater quality is crucial, considering the potential risk of groundwater contamination and its effects on human usability. In recent years, models based on artificial intelligence approaches have been employed due to the non-linear and complex nature of geohydrological issues. Khorramabad is one of the important regions of Lorestan province, where the drinking water of the city is supplied from groundwater resources...
