Spring water must be collected only at the spring or through a bore hole tapping the underground formation finding the spring. Spring water collected with the use of an external force must be from the same underground stratum as the spring and must have all the physical properties, before treatment, and be of the same composition and quality as the water that flows naturally to the surface of the earth. Consumers can trust that bottled water is safe for many reasons. This ensures that all bottled water sold in the United States meets these stringent standards. Consistent quality and taste are two of the principle differences between bottled water and tap water.
Quality is in every container of bottled water.
It's consistent and it is inspected and monitored by governmental and private laboratories. The U.S. Environmental Protection Agency has reported that hundreds of tap water sources have failed to meet minimum standards. Another factor to consider is the distance tap water has to travel and what it goes through before it reaches the tap. Taste is the other major reason people prefer bottled water versus tap water. Chlorine is most often used to disinfect tap water.
