Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

Just turning the water off for a day or so (even longer) doesn't make it unsafe to drink. If you didn't drain the pipes then the water should be no different than when you left.

Rick, so you are saying that after turning my home's main shut off valve off for 24 hours, opening the cold spickets so the water would drain before I left...and now that I'm home 24 hours later, after running the water for 20 minutes it is safe to use for washing, drinking, etc.? Thanks.

Yes that's what I'm saying. Turning the water off doesn't make it unfit to drink. But if you drained the water out of the pipes by opening several faucets then turning the water back on could stir up some sediment that clings to the inside of the pipes. If this is the case then letting the water run for a couple minutes will flush out any sediment. If the water flow from a sink faucet is reduced it's because that sediment is clogging the aerator and you'll have to unscrew it from the end of the spout and clean it out.
