Iodine

Iodine is a known chemical element that can be found in trace amounts in natural water sources, particularly in areas where iodine-rich minerals are present in the soil or rock. Iodine can enter water through industrial activities or as result of water treatment processes. Having disinfectant properties, it can be used as a water treatment method for emergency situations or outdoor activities where access to safe drinking water is limited, effectively killing or inactivating bacteria, viruses and other microorganism in water. When iodine, if used as a water disinfectant, it typically derives in the various forms such a tablets, solutions or crystals, which release iodine into the water acting as a germicide. The recommended contact time and dosage for effective disinfection varies depending on the specific product and water conditions, therefore it is important to note that long term and excessive exposure to high levels of iodine can have negative health effects. This is why iodine treatment isn’t typically used as a long-term disinfectant to water supplies and mainly employed in situations where safe water for consumption is temporarily unavailable, such as camping, hiking or emergency situations.
