Water pollution stands out as a significant environmental challenge confronting developing nations worldwide. The formulation of a mathematical model addressing both soluble and insoluble water pollutants revolves around ordinary differential equations. Through sensitivity analysis, an exploration of parameter values linked to the reproduction number is conducted, aiming to mitigate water pollution. The determination of the basic reproduction number for the water pollution model and an investigation into the model’s steady state are carried out. Numerical analysis underscores the pivotal role of water treatment in securing high-quality water for human consumption.
