Back in January 2003, Ted posted this:Charcoal filters actually make the sulphur smell worse. They do trap the odor, but when you shut water flow off, the sulphur migrates back out of the filter in to the surrounding water. That means that when you turn the water back on you just about get knocked over by the concentrated smell until you've flowed quite a bit of water through the filter. Chlorination does an excellent job of getting rid of sulphur smell. This can be as simple as dumping some bleach (you'll learn how much very quickly) down your well every couple of weeks. Bleach also helps with rust in the water, incidentally. Iron can't be removed from water, but rust (in reasonable quantities) can be removed by your water softener. Bleach and chlorine are oxidizers, so the "rust" the iron in the water, allowing it to be removed. If you've got a lot of iron in the water, a rust filter is in order, though, since it can destroy your softener. Here's a good link, too: //www.ytmag.com/cgi-bin/viewit.cgi?bd=nboard&th=359586
