Its all depend on what kind of chemical used to purified. If only killed pathogens and removed chemical then purified water is safe to drink.

Purified mean that it is safe for human consumption. There need to be a small quantity of free clorine in the water to kill off any bacteria and e-coli entering the water after the purification process. Clorine evaporate with time and if you are going to store the water for a while, the clorine levels must be increased to ensure that there is still clorine in the water when it reaches the consumers.
There are various ways to sterilize water (part of the purification process) but only clorine has a residual effect which ensure "safe" water to end consumers. If you are going to use the water immediately or you bottle water in sterilized bottles and seal it, the use of Ozone is a more environmentally friendly process.

It depends on how purified. Deionized(DI) water will damage your gut and cause a net water and salt loss. Think salt water fish in fresh water. Prolonged exposure will cause scaring and loss of blood flow and local tissue death.
Bottled water is not chemicaly pure and so its safe to drink.

Bottled vs. Tap
Whether bottled water is better than tap water, and justifies its expense, remains under debate. Stephen Kay, vice president of the IBWA, says member bottlers are selling the quality, consistency and safety that bottled water promises, and providing a service for those whose municipal systems do not provide good quality drinking water.
"Bottled water is produced and regulated exclusively for human consumption," Kay says. "Some people in their municipal markets have the luxury of good water. Others do not."
Thornley, of the Minnesota Department of Health, agrees that consumers can depend on bottled water's safety and quality. But he says consumers should feel the same way about the quality of their tap water. Tap water may sometimes look or taste differently, he says, but that doesn't mean it's unsafe. In fact, the most dangerous contaminants are those that consumers cannot see, smell or taste, he says. But consumers don't need to worry about their presence, he adds. Municipal water systems serving 25 people or more are subject to the federal Safe Drinking Water Act. As such, the water constantly and thoroughly tested for harmful substances, he says. If there is a problem, consumers will be warned through the media or other outlets.
"In lieu of being told otherwise, consumers should feel confident of the safety of their water," Thornley says.
Dr. Robert Ophaug, a professor of oral health at the University of Minnesota School of Dentistry, notes that tap water has another advantage many people don't think about: It typically contains fluoride. Many communities have elected to add fluoride to drinking water to promote strong teeth and prevent tooth decay in residents, though some groups continue to oppose this practice and believe it's detrimental to health.
Ophaug says bottled water often does not have fluoride added to it. Or, if it has been purified through reverse osmosis or distillation, the fluoride may have been removed. People who drink mostly bottled water, especially those who have children, need to be aware of this, he says. They may need to use supplemental fluoride that is available by prescription from dentists or doctors. The supplements are usually recommended for children ages 7 to 16. Fluoride supplements cost around $15 for a three-month supply.
"At the least, inform the children's dentist or doctor that you are relying on bottled water," Ophaug says.
The IBWA says there are more than 20 brands of bottled water with added fluoride available to consumers today. When fluoride is added to bottled water, the FDA requires that the term "fluoridated," "fluoride added," or "with added fluoride" be used on the label. Consumers interested in how much fluoride bottled water contains can usually find out by contacting individual companies directly.

It depends on how 'purified' it is. Generally, 'purified' means that all harmful chamicals and disease microorganisms have been removed so that it's safe for human consumption.

In the short term it is the safest. In the long term it will kill you. Natural water contains nutrients that you need for good health.
