Tap water comes from reservoirs, wells, rivers, or lakes. The water goes through a water treatment plant in most areas before it comes out of your faucet. Tap water is generally safe, but some areas experience problems with the safety, quality, or taste of their tap water.  Bottled water can come from many different sources. Some bottled water even comes from the same original source as tap water. In this case, the water is typically treated with distillation, ozonation, reverse osmosis, or absolute 1-micron filtration before it's bottled to increase the quality. These treatments may allow the water to earn the label of "purified water."
