Reply #16: It means there is a little hydrogen sulfide down in the water table, common.

It's harmless just unpleasant.

The way to remove it is exposure to oxygen.

Put it in a pitcher and a few hours later the smell will have gone from just oxygenating with air.

If it isn't very strong, using a galvanized steel tank on your well, and keeping a proper air head in it using an air control valve system will allow the air in the tank in contact with the water to remove the smell before it gets to the house.

The smell is very very common when using a tank on your well with an air bladder in it as the water does not contact any air before it come out of your faucet. They are usually blue metal tanks with an air fitting on the top, I would never use one on my well as I like having the water contact the air in the tank and letting it oxygenate.

If it is very strong, you can buy a chlorine injector that can be set to inject just enough into your well tank to oxidize the sulphur.

This is standard water well stuff.
