Unless local tap water is suffering through some unexpected contamination upset, it is every bit as good as is bottled water. Now, some might argue that bottled water has fewer micro-contaminants and is devoid of fluoride and chlorine.
For those of that position, for them bottled water is superior. However, there is no substantial research that shows this water to be bettered than bottled water.
When we speak of bottled water we are most likely talking about the more popular products such as Dasani, Aquafina, Nestle, and a lot of generic grocery store type bottles. These are all excellent products. They begin with tap-water and go through a process of
- Sediment filtration
- Activated Carbon
- Water Softening
- Reverse Osmosis
- Storage, Recirculation, and Re-pressurization
- Sanitization consisting of some combination of ultraviolet light/ozonation/sub-micron filtration.
At some point in the process, minerals are added for taste because RO water does not taste good.
There is a second class of bottled water that is the flimflam part of the water industry, and frankly, it is shameful. These are products that capitalize on people who fear water toxicity or who are looking for health benefits/miracles. These junk products include alkaline water, hydrogen water, black water, and God only knows how many other permutations there are. These products are no better than common tap water and their ridiculous claims do nothing but add expense to the customer.
The third class of bottled water includes really cool high-class/fancy brands like S Pellegrino, Perrier, and other natural mineral waters. The majority of these are great, healthy, well-packaged water and seldom are pushed to take advantage of people. They are expensive, come from exotic places, have interesting and unique tastes and look good on your restaurant table.
At the end of the bottle, the human body needs water. Whether it comes from a tap, a bottle, a beverage, a filter, or from food, our body doesn’t care. If you like the convenience and taste of bottled water? Enjoy it. Just don’t buy it because you think one water is better for you. They are all the same.
