How Much Iron is Too Much in Your Drinking Water?

Iron is a positive ingredient in your water supply and, for many, an invaluable dietary supplement. But too much of a good thing is, well, not a good thing. In fact, an excess of iron in your drinking water can cause abdominal and bowel problems. If you’re experiencing those right now, are they attributable to iron? They might be if your water is tinted brown or red.

Iron problems are more frequent in homes with well water supplies which are not subject to the same federal standards that govern public water supplies.  The Penn State College of Agricultural Sciences recommends a maximum of 0.3 milligram of iron per liter of water.

To test your water for higher-than-recommended iron levels, pour yourself a glass and let it sit for a few minutes. If the color turns brown or red, as mentioned previously, you likely have ferrous iron in your water. However, if your water comes out of the tap with a red or yellow tone, your water probably contains ferric iron. While your body can process both types, ferrous iron is easier for your body to absorb, but also more likely to make you sick. 

The most common symptoms of too much iron in your water are nausea, cramping, vomiting and constipation. Don’t let any of these symptoms linger without seeing and consulting your doctor since, in severe cases, iron toxicity leads to organ damage and other serious consequences.

If you have any concerns about your home water supply, contact Your 1 Plumber and ask about the benefits of a whole-house water-filtration system, one that keeps the levels of irons and minerals at acceptable levels so you’re drinking the cleaning and healthiest water possible.
