Sulphur - Rotten Egg Odour in Cold Water

Hydrogen sulphide gas is the form of sulphur responsible for the "rotten egg" odour which people find objectionable. It gives off an objectionable "rotten egg" smell from either the cold or hot water and in high concentrations can be extremely corrosive to copper plumbing and chrome fixtures. Sulphur will appear in water from a light to dark grey and can leave black stains and deposits in plumbing fixtures.

Most sulphur water contain from 1 to 5 ppm of hydrogen sulfide. Areas of Manitoulin Island have tested in excess of these numbers. High levels of sulphur will often result in a lowering of the PH level of water.

The treatment for sulphur varies dramatically with the level present in water, the type of pumping system and the other contaminants found in the water supply. Accurate on-site testing is required to determine a viable treatment system.
