I think the tap water is safe if not safer than bottled water anywhere in this state. I've had chemistry professors (UCI) tell me that. Something about plastic bottled water that when it warms it releases chemicals in the plastic that are not very good for your consumption. But I can't convince my wife who says the bottled water simply tastes better. So we have all these plastic bottles around that not only take up space but are unfriendly to the environment-although I think somehow some are recyclable. To be honest I cannot tell the difference in the taste -especially if I fill up an empty plastic bottle with tap water and put it in the refrigerator.
