There are few other water problems quite so recognizable as the water that comes out of the tap smelling like rotten eggs. Numerous homes suffer from this unpleasant odor. Here is why you are experiencing a “rotten egg” smell in your water, the effects it can have, and how to treat it.
Rotten egg smell in your water supply is the result of the presence of sulfur. Hydrogen sulfide gas actually causes the smell. This gas, and the resulting offensive smell, is most commonly found in well-water or ground water.
Sulfur water has no known health effects, though it can sometimes change the taste of water. Metal items like silverware can discolor or turn a blackish color when washed often, and anyone with sulfur water can attest to the difficulty of getting truly clean clothes. Hydrogen-sulfide water literally lessens the effect of detergent, as well as corrodes any exposed metal parts in the washer.
