I'm not a well expert, but from what I've read is that chemical runoff could get into shallow sandpoint wells, but if you drill a 200ft deep well, that water is millions of years old.

Did a quick search, and this link [1] from what appears to be a reputable source says most household wells are pulling up water that is less than 10 years old. Granted that probably varies a lot by region. I've heard of a fair number of people that have their wells go bad and need to drill deeper to get clean water. Found this page [2] that lists registered well depths here in Iowa. Seems that somewhere in the 300-400ft range is common. Deeper for municipal wells.
