What causes my well water to have a fowl (rotten egg) type odor?

This bad odor is usually caused by a bacteria that converts the sulfate in water to sulfide. Generally this problem can be remedied by chlorinating the water well. It is a good idea to have the well water tested for coliform (harmful) bacteria at this time.

What is the white residue left on the ground or on objects that have been exposed to my water?

The aquifer in this area (City water included) contains a large amount of dissolved minerals. When water evaporates, the minerals remain and are visible as white or brown deposits. This is normally a combination of calcium, magnesium, iron, and chloride.
