What’s causing your water to smell bad?

There are various factors contributing to unpleasant odors in your household’s water. Although these issues often arise from well water, even city water can develop disagreeable smells.

The most noticeable odors tend to appear in areas exposed to heat and steam, such as showers, dishwashers, and during cooking. However, most complaints are typically associated with water used for drinking or brushing teeth.

If your water smells like:

Rotten eggsOne of the most common culprits for smelly well water is sulfur. It can give your water a rotten egg or sewage-like odor. Sulfur can enter your well water through natural geological processes or from decaying organic matter in the ground.
MustyMusty: The presence of slime in your toilet tank or evidence of iron in your water, like red stains on fixtures or laundry, could indicate iron bacteria. While it’s not a health risk, it can be a nuisance.
SewageBacteria, especially sulfate-reducing bacteria, can grow in well water and produce hydrogen sulfide gas, causing a distinct, foul odor.
GasolineIf the problem started suddenly and there is a possibility of a gas spill nearby, stop using the water until it is tested. If gasoline is ruled out, it could be iron or sulfur bacteria.

Is bad-smelling water a health risk?
