Asked by gabrielle

what could be a possible source of sulfates found in a supply of drinking water?
Answered by E.G.
Some rocks and even some soils contain sulfites; as the water runs over (and through) these, it picks up some of the sulfates.
Answered by E.G.
OOPS - I meant of course "SULFATES" (not sulfites.)
Answered by E.G.
Certain industrial wastes can also supply sulfates to our water, as does rain.
