Your well water smells like rotten eggs because hydrogen sulfide gas or sulfur bacteria are likely affecting your water supply. In Jacksonville, this smell can show up in private well water, plumbing lines or even your water heater. The strong odor is usually a sign of water quality issues that can damage your plumbing and appliances and make the water unpleasant to drink.
As a homeowner, you should not have to guess what is causing the smell or whether your water is safe to use. CGC Home Services provides free water quality testing to identify the source of the rotten egg smell and recommend the right solution.
Why Your Well Water Smells Like Rotten Eggs
The reason your Jacksonville water smells like rotten eggs is the presence of hydrogen sulfide gas in your groundwater supply. Private wells draw from underground aquifers where sulfur bacteria interact with sulfates, producing the gas as a by-product. The gas releases its odor the moment water flows through your pipes and can also build up in your water heater, making the smell worse at the hot water tap.
How Sulfur Smell Can Affect Your Home
A rotten-egg smell in your well water can create several problems throughout your home:
- Unusable drinking and cooking: A strong sulfur odor makes tap water unpleasant to drink or use in the kitchen. High hydrogen sulfide levels can also cause stomach discomfort.
- Embarrassing odors in your home: Rotten-egg odors are often most noticeable when water runs in bathrooms, kitchens or laundry rooms. As a homeowner, you may also worry about guests noticing the smell when they wash their hands or use water in your home.
- Potential health issues: While hydrogen sulfide at typical residential levels is not acutely toxic, very high concentrations warrant attention and testing.
- Staining on fixtures and laundry: Hydrogen sulfide reacts with metals, causing black staining on drains and fixtures. Combined with iron or manganese, it can also leave yellow or black marks on laundry.
- Pipe and appliance corrosion: Hydrogen sulfide in sulfur water can corrode pipes and other metal components of your plumbing. Over time, untreated sulfur odor issues may contribute to wear on water heaters, dishwashers, washing machines and fixtures.
- Uncertainty about the cause and next steps: Without a water test, it’s hard to know whether the smell is coming from your groundwater supply, sulfur bacteria in your well or pipes or a combination of sources. Each cause has a different fix, which is why professional testing is the starting point for any solution.
