Bottled water is not necessarily considered purer than tap water. Other than health risks, drawbacks to bottled water include environmental pollution, expense, and sustainability.
While drinking bottled water may seem perfectly fine, science shows drinking tap water is generally more approachable and safe because it is held to stricter safety regulations and quality control. Yes, bottled water is more portable and efficient in some cases; however, things to take into account include the cost for transportation, the manner in which it’s being transported, and how much of water sources is being drained gradually (specifically in water-scarce communities).
