If your source water runs through an area where naturally occurring sulfur is present, some sulfur may dissolve into the water. We provide a diagnostic procedure to track down the source of sulphur smells in water just below.
Some of this dissolved sulfur turns to the gas, hydrogen sulfide, and this can give the water a rotten egg type smelly odor. Sulphur odors can also be caused by a failing hot water heater component, or by certain bacteria in the building plumbing system, conditions we also discuss below. Sulphur smells in water can also occur in rivers, lakes, streams, ponds, and can be caused by anoxia and algae which in turn may be caused by high nitrogen from agricultural runoff - a condition we discuss at WELL WATER CONTAMINANT SOURCES.
Watch out: methane odors in a building water supply can be explosive - see METHANE GAS SOURCES
Watch out: Sulphur smells, rotten egg smells, or sewer gas smells can be caused by a variety of problems that we describe here. The sulphurous odor may be due to sulphur in the building water supply, bacteria in water, deteriorating water heater electrodes, dangerous sewer gas leaks, hydrogen sulfide gas forming in the water heater itself, even contaminated drywall or perhaps human or animal flatulence. Some of these gases and the implications of their source can be very dangerous, as we describe here and in related articles.
If the source of rotten egg smells or sulphur in your building is not traced to a water supply problem, see these related articles
