I have a sulfur smell (I think) in the water of the upstairs bathroom faucets. The smell is defiantly in the water coming out of the faucet and not sewage gas coming from the drain. It started about a year ago and as not spread to any other water outlets in the house. I have shocked the well twice but it has not affected the smell. Does anyone have any idea what could cause a water smell in only two faucets?

Sounds like you have bacteria growing in your faucets. First remove the aerators and soak them in bleach or CLR. If that doesn't cure the problem the faucets will have to be opened up and flushed out with bleach or CLR.
Good luck, Tom
