Sulfur in Well Water
Sulfur is not regulated as a primary drinking-water contaminant, so there is no official level of sulfur that represents a threshold between healthy and unhealthy concentrations. Sulfur gases in water are actually a compound of sulfur, called hydrogen sulfide. Hydrogen sulfide (H2S) is sometimes present in well water. A few tenths of a milligram of hydrogen sulfide per liter can cause drinking water to have a rotten-egg odor. While unpleasant, it is not harmful to health. This unpleasant smell can be removed with a Kinetico Sulfur Guard.
