Chlorination System

| What is the best newsgroup/forum for asking questions about water systems?
I recently purchased an acreage with it's own well, and I have a number of
questions regarding the water system. It consists of a large pressure tank,
a retention tanks, a chlorination system, and a carbon filter.
1) I have read that chlorine "oxidizes" the H2S in the water. What is the
chemical formula for this reaction? I'm just curious. What is the
composition for Hypochlor 12 that I use?
2) It is my understanding that the chlorine removes the H2S by converting it
to elemental sulphur (or some by-product thereof). Is the chlorine (at 1 to
4 ppm) also sufficient to kill any H2S producing bacteria in the system?
3) The pH of my H2O is between 8 to 8.4. I have read that at these levels
H2S does not readily dissolve in the water. Can someone elaborate on why?
4) When I bought the house, the carbon filter was in by-pass (chlorine
injected at 4 ppm before retention tank and coming out at 1 to 2 ppm after).
I have left it that way. There is a smell to my water, but I wouldn't
classify it as a rotten egg smell. It is similar to the smell you would
find at a place like Banff hot springs (the Canadians will know what I
mean - very popular tourist destination up here). I would categorize it
more like the smell of sulphur. Is this typical?
Thank you,
Chris

Cl2 + H2S ==> 2 HCl + S

| Thank you for the link - very informative. If the by-product of oxidizing
the H2S is HCl, why does my water have such a high pH (around 8 to 8.4)? I
assume it must be because the H2S is measured in ppm, and there simply isn't
enough HCl generated to be of any consequence?
