This document compares bottled water to filtered fountain water across several criteria. A blind taste test with students found that many could not tell the difference between bottled and fountain water. Bottled water is less regulated and may contain contaminants while plastic bottles can leach chemicals like BPA. Producing and transporting bottled water uses far more resources and causes environmental damage compared to tap water. While bottled water costs about 500 times more per liter, it offers no benefits over filtered fountain water in terms of safety, taste or environmental impact. The document encourages using refillable bottles instead of purchasing bottled water.
