Aluminium contamination in groundwater is a significant environmental concern, particularly in regions with high levels of industrial and agricultural activities. Abohar, a city in Punjab, India, is one such region where groundwater contamination has become a major issue. This study aims to assess the aluminium contamination in groundwater of Abohar, Punjab, using a mathematical modelling approach. The study involves the collection of groundwater samples from different locations in Abohar and analysis of aluminium concentrations using atomic absorption spectroscopy (AAS). A mathematical model is then developed to simulate the transport of aluminium in the groundwater system. The model takes into account various factors such as soil properties, groundwater flow, and aluminium adsorption-desorption reactions. The results of the study indicate that the aluminium concentrations in groundwater of Abohar exceed the permissible limits set by the World Health Organization (WHO) and the Bureau of Indian Standards (BIS). The mathematical model developed in this study is able to simulate the aluminium transport in the groundwater system with reasonable accuracy. The study highlights the need for effective management strategies to mitigate aluminium contamination in groundwater of Abohar, Punjab. The findings of this study can be useful for policymakers, water resource managers, and researchers working in the field of environmental science and engineering.
