Iron is present in nature in the form of its oxides, or in combination with silicon or sulfur. The soluble Iron content of surface waters rarely exceeds 1 mg/L, while ground waters often contain higher concentrations. The Indian Drinking Water Standard for iron is 0.3 mg/L, as Iron concentrations in excess of 0.3 mg/L impart a foul taste and cause staining. High concentrations in surface waters can indicate the presence of industrial effluents or runoff.
Higher iron content of water also affects the wildlife life fish, prawns etc. specially in closed systems like biofloc or RAS systems. Test your water with Lifesonic Iron test kit before using the water to safeguard your health and the health of your livestock.
