Why Does My Water Smell? Common Causes and Solutions
If your tap water has an unpleasant odor, you’re not alone. Smelly water is one of the most common complaints homeowners have. Fortunately, it’s usually fixable once you identify the cause.
Different smells often point to different water issues and may depend on where your home or business is located.
Rotten Egg Smell
A rotten egg odor is typically caused by hydrogen sulfide gas, which may occur naturally in groundwater or result from bacteria in plumbing systems.
This smell is especially common in private wells, hot water systems, and areas with high sulfur content in groundwater. While sulfur odors are usually not harmful at low levels, they can make water unpleasant to drink or use.
Possible solutions include:
- Aeration systems
- Oxidation filtration
- Activated carbon filtration
Chlorine Smell
Municipal water supplies often use chlorine to disinfect water. If the chlorine smell is strong, it may be due to seasonal treatment adjustments, long water stagnation in pipes, or high chlorine dosing from your local utility provider.
Thankfully, there’s a solution! Carbon filtration systems, like those found in EcoWater’s reverse osmosis drinking systems, are highly effective at reducing chlorine taste and odor.
Metallic Smell
If your water smells metallic, it may contain elevated levels of certain minerals, including iron, manganese, or copper. These minerals are common in well water and may also cause staining on sinks and fixtures.
Water softeners or specialty filtration systems can help remove these contaminants. Iron and purpose filters are especially effective for resolving high iron or manganese, a common problem in well water in Southern Minnesota.
Why Smelly Water Shouldn’t Be Ignored
Even when odors are not harmful, they often signal underlying water quality problems that may worsen over time.
Addressing odor issues can help improve drinking water taste, protect plumbing and appliances, reduce mineral buildup, and improve overall water quality. The United States Environmental Protection Agency recommends testing water whenever noticeable changes in taste, odor, or appearance occur.
The Best First Step: Professional Water Testing
Because different odors have different causes, testing is essential before choosing a treatment system.
A professional water analysis can identify water hardness, mineral and chlorine levels, and even potential bacterial concerns. Please note: our free basic water testing is only for hardness, chlorine, and iron levels. For more in-depth testing (bacteria, other minerals, etc.), a sample of your water may need to be analyzed at an accredited water lab.
From there, a customized solution, such as a softener or filtration system from EcoWater, can eliminate odors and improve water quality throughout your home or business. To schedule your free basic water test, please contact us here.
