Activated Carbon (AC) does remove chlorine and chloramine from water. That comes from my former professor at University of Florida who specializes in activated carbon treatment and research.
Hah! What is a Gator doing in Indiana?
Personally, I hate the smell of sulfur which is commonly encountered here in Florida from low-tide and/or non-potable water sources used for lawn irrigation. I also seem to be particularly sensitive to it when tasting beer styles known to have acceptably high sulfate levels (e.g., bitters).
Martin, can you explain the difference to us between sulfate and sulftite? I don't buy the notion that sulfites are boiled off. That is new information to me.
The sulfur smell that you describe is hydrogen sulfide. H2
S. Often refered to as "rotten eggs smell." It is common in shallow groundwater. Much of Florida's irrigation water comes from shallow wells. H2
S is also a product of bacterial breakdown of organic matter, such as sargasso seaweed rotting at low tide, or anaerobic mud flats exposed at low tide.
Deep water wells in Florida also have H2
S dissolved in their water. The H2
S is a dissolved gas that is removed by aeration of the well water over a cascade or through an aeration tower, or it is reacted with ozone injection. H2
S removal is quite necessary to make much of Florida's potable water platable.
Both sulfite and sulfate are divalent anions. The sulfate molecule has an additional oxygen atom:
Sulfite = SO32-
Sulfate = SO42-
