I live with an earth scientist and he says what you did ..it will have those metals there forever...and he said it is the arsenic making it orange.

This is why one should always have a way to get clean water if the primary source is contaminated.

Well your resident 'earth scientist' is wrong. The orange isn't due to arsenic at all. It's due to hydrated iron oxide, mainly limonite, and jarosite, which comes from the weathing of pyrite. So it's basically rust.
