I've always used jugs of drinking/spring water from wally world for my brewing and have had no issues from it at all. Works great and since I do partial boils, I can put my top up water in the fridge to speed cooling of the wort.
Most batches I've done ended up taking on phenol tastes when using bottled water. I only do partial boils though, so I would top off with it too. After using my well water for the last batch, it was delicious.
