Sulfur smell from well water/drain?

[msdaisy]

There's a strong sulfur odor in our basement right now. Went down to do laundry, and noticed the smell in the hallway. I'm wondering if its coming from the drain? Or possibly has something to do with the well water?

Anyone else have this kinda problem?

Are your fingertips, nails, cuticules turning black? If so, sulphur is in the water. Pour some known fresh water in all the drains, enough to flush the P-traps and see if the odor returns.

It's possibly iron bacteria in your well water.
It could also be the drain though.
Try pouring a cup of Clorox in the drain
