Why Does My Well Water Smell Funny?

May 18, 2022

It’s not common for water wells to have a bad smell. As you know, water doesn’t have any detectable odor, and you should not expect such a smell from your well. However, if your well is not properly maintained, you might get a funny smell. Sometimes it can become untenable by spreading to every corner of your property. To prevent this, you need to learn how to maintain your water well pump.

 Understand the Source of the Bad Smell

Before you can take steps to fix the problem, you need to understand where the bad smell is coming from. If your well water smells funny, it’s most likely due to bacteria. This happens when there’s too much organic matter in the water, such as leaves or twigs. The organic matter provides food for the bacteria, allowing them to grow and multiply.

Another possibility is that your well water smells like bleach because it contains high chlorine levels. If you use a lot of bleach when you clean your well, it can seep into the water and make it smell funny.

Install an Aeration System

One way to fix the problem is to install an aeration system. This system injects air into the water, which helps to remove the bad smell. The air bubbles also help break up any organic matter in the water, making it easier for the bacteria to decompose.

You can either purchase an aeration system or a DIY one. If you buy a system, make sure to get one specifically designed for well water. These systems are usually more effective than those designed for municipal water.

If you decide to DIY an aeration system, you’ll need an air compressor, a tank, and some tubing. You’ll also need a diffuser, a type of device that helps distribute the air bubbles evenly throughout the water.

Use a Well Water Filtration System

Another option is to install a well water filtration system. This will remove any impurities from the water, including the bacteria causing the bad smell. There are many filtration systems available on the market, so you’ll need to research to find one that’s right for your home.

Some well water filtration systems are designed to be used with an existing aeration system. Others can be used on their own. If you decide to use a filtration system, get one that’s specifically designed for well water.

A good well water filtration system will remove all the impurities from the water, leaving you with clean, fresh-tasting water. It’s an investment that will pay off in the long run, as you’ll be able to avoid costly repairs to your well pump.


Keeping your water well clean and fresh is vital for your health and your well pump’s longevity. If your well water smells funny, it’s most likely due to bacteria or high chlorine levels. You can fix the problem by installing an aeration system or a filtration system.
