When the spill happened here in West Virginia, WV American Water issued a "DO NOT USE" order. Meaning it was only to be used for fire fighting and sanitation purposes. If you didn't hear about the order, you had to be living under a rock or something.
As a victim of this spill, I can assure you that as soon as you drew a glass from the tap, you would be more than compelled to dump it down the drain. Yes, it's smelled THAT BAD. A normal person would not drink that water of their own free will. I had to force myself to bath in it, even after we where cleared to use it.
That spill happened on Jan 9th, 2014 the do not use order was completely lifted a few weeks later.
It was over a month before the odor left the pipes at our home. Even after the extensive flushing.
We didn't start drinking it again until sometime late March or early April, after it had been tested by independent labs outside of local influence.
I know of some people around here who still only use bottled water and won't drink the tap water and that was 9 months ago.
To answer the question, as of right now, and prior to "Aquapocolypse" we have always drank from the tap, even when it comes from the tank in our MH.
On another note, and complete off topic, that day I realized just how much we take clean water for granted. It really sucks to have a supply of water at the tap that is completely useless for anything other than flushing the toilet.
