Sulfur water treatment help

I recently moved into an old farm house which has a very bad sulfur well water problem.  There was a culligam chlorine system already in place.  Unfortunately with such high sulfur 60ppm the chlorine system was unable to properly treat the water.  System injected straight chlorine into a 250 gallon holding tank. So we would go from extremely high chlorine to strong sulfur smell.  Could never get system regulated.   Culligan recently installed a new hydrogen peroxide system with secondary chlorine treatment. System worked great for a week or so with no smell at all. After the first week the water began to smell like sulfur again. Slowly at first and got worse each day. If we run the water hot or cold for a few seconds the smell would go away.  Over time the time needed to run the water before the smell went away increased.  Can anyone provide the reason for the increase smell over time?  Culligan says that this is common.  Seems that once the lines are flushed the water in good but why is this happening?  

Hi Pete,

Wish I had an answer for you.  I also have sulfur water but I just deal with it.  Mine may not be as bad as yours, though.  And, yes... I have found when I go away for a couple days and it sits that it's worse in the beginning.  Since sulfur is a gas, I put the water in my Berkey and the gas dissipates and the water is great to drink.  Many people around me have good filters that completely remove the smell but I'm not sure what kind of filters they are.  I know I'm being no help... just commiserating, I suppose!

I gave up and installed rainwater collection. The rain water is piped into the hot water side of my house since the smell mainly came from the hotwater side. The house smelled like sulphur after a shower.

I keep a berkey full of rain for drinking, making ice, etc.

The only thing that keeps me from all rain is the amount of storage i would need. I reached a good compromise.
