V - Iron
Iron is a naturally occurring element that can be found in various forms in water sources. While small amounts of iron in water can be beneficial for human consumption, high levels of iron can cause a variety of problems. It is important to test for iron in water to ensure that the levels are within safe limits. Iron can be present in water in two forms: dissolved iron and iron particles. Dissolved iron is iron that is present in the water in a chemical form, while iron particles are iron that is present in the water in a solid form. Both forms of iron can cause problems if the levels are too high. Overall, testing for iron in water is important because it can help to identify and address problems caused by high levels of iron, and it can also be used as a tool to identify potential sources of contamination. By testing for iron in water, it is possible to ensure that the water is safe to drink and that it does not cause damage to plumbing fixtures or other items that come into contact with the water.
