We had that sulfur smell in our well water in south Texas. It will dissipate if the water is allowed to sit for awhile.
Two forms of sulfur are commonly found in drinking water supplies: sulfate and hydrogen sulfide. Both forms are nuisances that usually do not pose a health risk at the concentrations found in domestic water supplies.
Sulfates are a combination of sulfur and oxygen and are a part of naturally occurring minerals in some soil and rock formations that contain groundwater. The mineral dissolves over time and is released into groundwater. Sulfate may have a laxative effect that can lead to dehydration and is of special concern for infants. With time, people and young livestock will become acclimated to the sulfate and the symptoms disappear. Sulfur-oxidizing bacteria pose no known human health risk.
Hydrogen sulfide is flammable and poisonous. Usually it is not a health risk at concentrations present in household water, except in very high concentrations. Such concentrations are rare. Hydrogen sulfide odor is associated primarily with the hot water system. Water with hydrogen sulfide alone does not cause disease.
The offensive odor of hydrogen sulfide gas generally makes testing unnecessary. Most people recognize the "rotten egg" or "sulfur" odor and proceed to correct the problem. Hydrogen sulfide is one of a few water contaminants that can be detected at low concentrations by the human senses. The gas readily dissipates when water is exposed to the atmosphere.
Sulfate
The Environmental Protection Agency (EPA) standards for drinking water fall into two categories -- Primary Standards and Secondary Standards. Primary Standards are based on health considerations and are designed to protect people from three classes of toxic pollutants -- pathogens, radioactive elements and toxic chemicals.
Secondary Standards are based on taste, odor, color, corrosivity, foaming and staining properties of water. Sulfate is classified under the secondary maximum contaminant level (SMCL) standards. The SMCL for sulfate in drinking water is 250 milligrams per liter (mg/l), sometimes expressed as 250 parts per million (ppm).
The water is Florida has to be tested by the Helath Department and they would not allow high concentrations of sulfate. It must remain in an acceptable range
Hydrogen Sulfide
Although many impurities are regulated by Primary or Secondary Drinking Water Standards set by the EPA, hydrogen sulfide is not regulated because a concentration high enough to be a drinking water health hazard also makes the water unpalatable.
The odor of water with as little as 0.5 ppm of hydrogen sulfide concentration is detectable by most people. Concentrations less than 1 ppm give the water a "musty" or "swampy" odor. A 1-2 ppm hydrogen sulfide concentration gives water a "rotten egg" odor and makes the water very corrosive to plumbing.
