Why does her Johnsburg well water taste metallic?

It looks clear but the water from that Johnsburg water tastes metallic.

The water at Heidi’s house in Johnsburg tastes great. She’s occasionally bragged about that to friends who live where they have city water. Heidi’s water comes from a private well out back. So, when she brags, she usually says something along the line of, “Our Johnsburg water tastes wonderful and, the best part is, we don’t have to pay a water bill every month.” But, lately, Heidi’s water has tasted a little funny.

In fact, if you pressed Heidi, her husband or the children about it, they’d probably say that the water has kind of a metallic taste to it.

What would make the water from Heidi’s well taste metallic? One likely culprit is iron. That may explain why, when she uses the water to make tea or coffee, the metallic flavor overpowers the beverage and gives it a kind of inky appearance.

Her water could also have a metallic taste because it has low pH (potential Hydrogen) levels.

The good news about the prior potential problem is that iron is not necessarily bad for your health. As humans, we actually require some iron in our bodies to maintain our health. The EPA guideline is 0.3 milligrams of iron per liter of water but that’s only a guideline. Even with more, you’re probably okay. But, too much iron in your water can cause problems, such as:

• Buildup of iron can lead to clogged water pipes
• Too much iron in the water can stain dishes, sinks, laundry and other household items that come into regular contact with the water
• Along with an offensive metallic flavor in water, it can also present an unappetizing dark appearance to food

The question, of course, is how did the iron get there?

One way contaminated water may get into the well is through seepage. A key component to prevent seepage is the well cap. This is the part at the top of the well you see in your backyard. If sealed properly, the well cap keeps ground water out of the well. A particular threat is melting snow that can build up around the well cap. But, if the well cap is good the melting snow won’t get into the well.

If the well cap is bad, seepage isn’t the only potential problem. For instance, with a bad seal, a well cap can allow bugs, such as earwigs, to make themselves at home in your well. And who wants to drink a glass of water that served as a swimming pool, and more, for a colony of earwigs?

Another way for iron to get into the well is through corrosion. Frankly, in this case, the well is susceptible to rust. The pipes are exposed to air and water and that makes them rust. Over time, the rust begins to build up and flake off. Falling into the well water, the rust dissolves and is carried into your home as tiny metallic molecules in your water.

What can you do about iron in your well water? The most common solution is a water softener. A water softener removes minerals, including iron, from the water. If operating correctly, a water softener can eliminate your problem with metallic-tasting water.

Chlorinating your well can also remove the iron bacteria from your water. This is one reason you should chlorinate your well each year. But, iron bacteria in the water is only one reason to chlorinate your well; you also want to chlorinate your well to remove other bacteria and micro-organisms from your well water.

If the pH levels of your Johnsburg well water are low, there are also treatments that will neutralize this problem.
