Does Your Tap Water Smell of Sulfur?

Does your tap water smell of sulfur? If you notice a rotten-egg smell, that means the gas has entered your water supply. If this is the case, get in touch with Aquarius Water Conditioning. We have a water purification system from Kinetico that will get your water back to normal in no time. The following is some of the reasons why sulfur gets into water, some of the potential health impacts, and how we can help you get rid of it.

Causes of Sulfur Odor in Tap Water

Does Your Tap Water Smell of Sulfur?One of the common culprits behind the sulfur smell in tap water is the activity of sulfur bacteria. These bacteria thrive in environments lacking oxygen, such as poorly aerated water heaters or plumbing systems. As they break down organic matter, they release hydrogen sulfide gas, which imparts the characteristic rotten egg odor to the water.

Hydrogen sulfide gas is a naturally occurring compound resulting from the decay of organic matter. It can seep into groundwater or infiltrate water supplies, leading to the unpleasant sulfur smell when the water is used.

Certain chemical reactions occurring within the plumbing system or water supply can contribute to the formation of hydrogen sulfide gas. This may involve the interaction of sulfur-containing minerals with bacteria or other chemicals present in the water.

Health Implications

While the sulfur smell in tap water is obviously unpleasant, it’s important to note that hydrogen sulfide gas itself, in low concentrations, is not usually harmful to health. However, prolonged exposure to high levels of hydrogen sulfide can cause symptoms such as nausea, headaches and eye irritation. In addition, the presence of sulfur bacteria may be a sign that you might have other harmful bacteria in your water. Get in touch with Aquarius Water Conditioning so we can check your water to see what’s happening.

Solutions to Address Sulfur Odor

If the sulfur odor is localized to hot water, flushing the water heater can help eliminate stagnant water where sulfur bacteria thrive. This can be done by draining a few gallons of water from the water heater through the drain valve.

If you have a well, improving the aeration of water can reduce the growth of sulfur bacteria. Installing an aerator or introducing air into the water supply can be effective in reducing the sulfur smell.

Kinetico filtration systems do an excellent job of removing hydrogen sulfide gas and the odors that come with it. These filters work by adsorbing the gas onto the carbon surface. In some cases, minerals like magnesium or iron can contribute to sulfur odors. Kinetico water softeners can help reduce these minerals, helping get rid of the unpleasant smells in your water.
