Is bottled water ok?

There have been a couple of questions about dieting lately and one of the things mentioned is drinking plenty of water. It is not that I do not like the taste of water but it is somewhat, shall we say, bland. I do like the 0 calorie flavored water and drink quite a lot of it during the day to dilute my uric acid.
Other than the obvious ecological effect of all those darn plastic bottles and that I am consuming “potassium citrate, potassium benzoate, sucralose, malic acid, acesulfame potassium, and tartaric acid” (but surely there are chemicals in my tap water) does this count toward my water intake for the day? Are there any adverse effects that would counteract any benefits from the water consumption.
