Bottled water has become a $4-billion-a-year industry in the U.S., according to the Natural Resources Defense Council (NRDC). The organization estimates that people spend 240 to 10,000 times more per gallon of bottled water than tap. Dietician Robin Kaiden says many in the medical community question whether bottled water can be bad for us, as it's contained in plastic that may leak into the water if left in the heat. Drinking tap instead will save you about $200 a year, and if you're still concerned, a basic faucet filtration will save you $150.
