: Sulfur occurs naturally in groundwater. Of course in some areas it is more pronounced. It doesnt mean the water is necessarily contaminated. Im assuming the source is a private well in which case periodic testing is always a good idea. The local health dept. may be able to run some simple indicators tests for little or no money.: A powder activated carbon (PAC) unit would probably do the trick. For a home, a unit containing about 3 cubic feet of carbon is appropriate. Depends on flow though. Make sure to get a point of entry unit.
