Regardless of the route the water follows to get to people’s houses, the fact is that safe drinking water is essential in everyone’s daily lives. For some, tap water fits their needs perfectly. For others, water that comes packaged in a bottle represents the best solution. In fact, bottled water sales have increased significantly in the past years. Americans spend billions of dollars per year on the bottles, making this type of water the fastest growing drink of choice in the U.S.A. Retail bottled water, the one people generally have access to and consume, accounts for 80% of the bottled water market and it is also its fastest growing segment. Bottled water consumers ingest an average of 736 mL per day.
Why bottled water is so popular?
One of the factors that contribute to the consumption of bottled water is the apparent lower quality of tap water’s organoleptics, i.e. tap water’s smell, taste and color. Indeed, much of the popularity of bottled water arises from the belief that tap water possesses a characteristic taste that the former option does not have. However, there is no robust scientific evidence that actually supports bottled water’s alleged superior taste. Because tap water supplies vary greatly all over the world, it is nearly impossible to obtain consensus regarding this topic, but many believe that if tap water does have some particular taste, that is due to the presence of chlorine, a safe disinfection substance used by most tap water suppliers. Bottled water suppliers prefer more complex disinfection methods, such as ozone or UV light, thus avoiding the traditional tap water taste. According to the US Environmental Protection Agency, it is important to note that bad taste does not necessarily mean bad water. Likewise, the lack of odor or color does not mean the water is safe. This is an interesting point to enlighten, as it has been examined that organoleptics influence people’s perception of what is safe and healthy. But, for example, the presence of certain microorganisms typically does not alter water’s taste and it still makes it dangerous.
Other reasons behind the high consumption of bottled water in the U.S. include the perceived health benefits of ingesting such water versus tap water. Although consumers don’t necessarily see tap water as unsafe, they consider bottled water to have a better effect on their health. In a study conducted at the University of Birmingham, UK, it was found that most people believed bottled water to provide with additional health benefits when compared to tap water, although the majority of them acknowledge these benefits to be negligible.
