If you’ve noticed that your tap water has become discolored or started to taste bitter or musty, then tannins might be the culprit. Though often overlooked, tannins can affect water quality and your home’s appliances. This brief guide will outline what homeowners should know about tannins in their drinking water and what you can do about them.
What Are Tannins?
Tannins are organic matter from plants and soil that result from natural fermentation processes. They can contaminate well water after it passes through peaty soil or areas with decaying vegetation. Tannins are also responsible for the bitter taste in some foods and drinks, such as wine. While they are not harmful to health, they can be nuisances and affect the taste and appearance of your water.
Homeowners should also know that tannins are secondary contaminants in water supplies. This means that federal agencies are not responsible for regulating tannin levels in drinking water. If your water source comes from a well or surface water near woods or fields, it’s more likely to contain tannins. Understanding why tannins are in your drinking water can help you better manage their presence.
How Do Tannins Affect Drinking Water?
Tannins don’t pose a health risk, but they can have other effects. They might leave stains on laundry and plumbing fixtures, making home maintenance more challenging. The yellow-brown color and earthy odor they impart can be off-putting, affecting the enjoyment of your drinking water. If you notice these signs, tannins could be present in your water supply.
How To Remove Tannins From Water
Dealing with tannins in water involves a few steps. First, test your water to confirm the presence of tannins. Then, consider installing a water softener or filtration system designed to remove tannins, such as an activated carbon filter or ion exchange system. If your home uses well water, regular maintenance and checkups from a water treatment professional can also keep your water tannin-free.
Understanding tannins in drinking water empowers you to take control of your home’s water quality. With the proper knowledge and tools, you can ensure your water remains refreshing and free from unwanted contaminants.
