I just built a new house and have water well about 2 years old. I have bad smell like rotten eggs. I'm not sure what to do. Its pretty bad!!

Hello jtking

Is the water well perhaps polluted ? Rrotten egg smell points at hydrogen sulfide (H2S) gas. Often caused by sulfate-reducing bacteria being present.

Have a look at this website with suggestions on how to solve that problem. (http://www.uldrinkwell.com/drinkwell/rotten_egg_smell.html)

Some Ideas here:

We have a lot of wells down here in Florida with " Sulphur Water". We aerate our water,(see image) to remove the gas. This simply means that the watrer is pumped, under pressure, through spray heads into a holding tank and then pumped back into the house from the tank. This make your stinky water fit to drink.

Good luck, Tom
