Tap Water: Tap water is the most efficient water available. Unfortunately, it is also vulnerable to occasional contamination. This is usually locally due to damaged pipes. This type of problem can be fixed in a timely manner. For the most part, the water is not much different from bottled water. It can be consumed directly from the pipes without harm. Even when the water is contaminated it is usually not fatal. Water pipes efficiently carry water across the nation as far as cost is concerned. There is no trash to pile up in your local landfill. Special filters are available for those who prefer filtered water. You could reuse the same bottle if you have an insatiable desire for bottled water.
Using tap water is obviously the better choice for the environment and for the survival of the human race as a whole. Production of bottled water is nothing but a mere convenience and a great deal of unnecessary pollution.
Bottle Water: Bottled water is usually filtered water from various sources. According to Imparo's Blog, sometimes bottled water can actually be filtered tap water. Bottled water itself has many different routes it has to take before it reaches you mouth. This increases the chances that it can be contaminated on the way. According to the Community Water Company of Green Valley, some bottled waters will occasionally contain microbial contaminants. Also bottled water usually loses a great deal of the natural minerals in water when it goes through the filtration process.
Many of those minerals are used by the body to maintain a healthy state. Water is nothing more then a mere rinse if you remove the minerals from the water. It is ironic that bottled water may not be as healthy as most people believe. There are of course some versions of bottled water that counteract this by artificially adding minerals. We all know that vitamins and minerals that have been separated from their source are never as effective as the real thing.
