Magnesium has smaller ionic radius and greater charge density. Therefore, it tends to form a sheath of six water molecules in octahedral coordination. Generally, because of lower geochemical abundance of magnesium compound to calcium, it concentration in water bodies is lower, fresh water shows magnesium concentration below 4.0 mg/L. For present study, the surface water i.e. pond (water sample) were collected in the vicinity of sugar factory and analysed every month throughout the year. So, we
