Introduction
If your water smells like sulfur or rotten eggs, it can be alarming. The odor is strong, unpleasant, and makes many homeowners worry about water safety. In most cases, the smell is not dangerous, but it does indicate an underlying plumbing or water quality issue that should be addressed.
At Springdale Plumbing Services, we help homeowners throughout Springdale and Northwest Arkansas identify the source of sulfur smelling water and apply the correct solution.
What Causes the Sulfur Smell in Water
The rotten egg odor is almost always caused by hydrogen sulfide gas. This gas forms when sulfur bacteria break down organic matter in low oxygen environments.
Hydrogen sulfide can enter your water system through several sources, and identifying the correct one is key to fixing the problem.
Problems with the Water Heater
If the smell only appears when using hot water, the water heater is often the cause. Inside the tank, naturally occurring bacteria can react with the anode rod, creating hydrogen sulfide gas.
Common signs include:
- Smell only from hot water taps
- Strong odor after water sits unused
- Odor strongest in showers
Flushing the water heater or replacing the anode rod often resolves this issue.
Bacteria in Plumbing Pipes
Sulfur bacteria can live in plumbing lines, especially in homes with well water or infrequently used fixtures. These bacteria are not harmful, but they produce hydrogen sulfide gas as they multiply.
Signs include:
- Odor from both hot and cold water
- Smell strongest when water first runs
- Odor present throughout the home
Disinfecting plumbing lines and installing proper filtration can eliminate bacterial growth.
Issues with the Water Supply
Sometimes the smell originates from the municipal water supply or private well. Seasonal changes, water treatment adjustments, or naturally occurring sulfur in groundwater can all cause odors.
Ways to check include:
- Asking neighbors if they notice the same smell
- Contacting the local water utility
- Testing well water for sulfur bacteria
If the source is the water supply, whole home filtration or treatment systems may be recommended.
Well Water Specific Causes
Homes on private wells are more likely to experience sulfur odors. Groundwater can contain sulfur compounds naturally, especially in certain soil types.
Common well related causes include:
- Sulfur bacteria in the well casing
- Organic material contamination
- Infrequent well maintenance
Proper well treatment and filtration systems usually correct the issue.
Is Sulfur Smelling Water Dangerous
In most residential cases, hydrogen sulfide in water is not harmful at low levels. However, it can:
- Make water unpleasant to drink
- Cause staining on fixtures
- Corrode plumbing components over time
High concentrations should always be evaluated by a professional.
