Bottled water is not recommended mainly due to environmental concerns such as the plastic waste and energy consumption as well as the potential health risks that can come from the plastic leaching and lack of stringent regulations when compared to tap water.
Bottled water is not really that much healthier than tap water and even some bottled water can still contain chlorine like your city tap water does.
Bottled water is just basically tap water that comes from a city water supply in most cases and is then filtered and may go through reverse osmosis.
Although some bottled water may come from a well on the bottled water factories property but the majority of bottled water is just the same tap water that you get from your tap and comes from a city water supply.
In some bottled water you can still taste the chlorine in it and so it's not any healthier than tap water and is much more expensive.
The healthiest water is well water without any additional chemicals added and without all the nutrients filtered out.
Well water contains natural nutrients including iron that you need for the body to function properly and keep you healthy.
Bottled water and many city supplies filter out and strip out all that healthy nutrients in the water and some city supplies and even some bottled water may add fluoride to the water along with chlorine.
Chemicals in drinking water including chlorine and fluoride can actually be bad for your health over the long term.
Other reasons for bottled water being not recommended are the plastic waste, energy consumption, resource depletion, chemical leaching, lack of regulation, microplastics, chemical exposure, contamination and taste and quality.
Some people find that bottled water has a different taste or quality when compared to tap water which can be a factor in choosing bottled water.
Bottled water can also be contaminated with harmful bacteria which can cause illness
And chemicals like phthalates and BPA can leach from plastic bottles into the water and potentially cause health problems.
And studies have shown that bottled water can also contain high levels of microplastics which are small pieces of plastic debris which can enter your body.
Bottled water is also also not regulated as strictly as tap water is in some countries which can allow for lower quality and more contaminants.
The production, transportation as well as disposal of plastic water bottles also contribute to plastic waste and pollution.
And the manufacturing, filling and distribution of bottled water also requires substantial energy which contributes to a larger carbon footprint than tap water.
The production of the plastic bottles also uses significant resources, including the water itself which can also strain local water resources.
