Actually I have drank water from lots of areas in India as being a businessman, I have to travel lenght and breadth of the country. Never ever I have caught any disease. What do I do? Simple, I used boiled & filtered tap water and according to me, its okay.

This is essentially in agreement with a post from an earlier thread: Bottled v Filtered Tap Water

Obviously water scarcity is an issue, but given human consumption for drinking is a small part of water usage in this country, filtration of tap water is a far more sustainable and environmentally friendly water source.
Just wondering if anybody had any thoughts on this, know of any relevant studies etc.

There are many grounds for justification for using tap water (further treated where applicable). Apart from the significantly higher environmental footprint (at several stages of the product life-cycle) and the general wastefulness of bottled water, there are cited estimates that it costs (the consumer) 840 times the price of tap water.
Another major aspect is the plastic wastes. Based on my own observations of material washed up and deposited on the high-tide mark of tropical beaches - in recent years the plastic component of that appears to become almost exclusively dominated by discarded water bottles.
This does not mean that the availability of bottled water does not have a role; it is particularly useful for environmental researchers or professionals who may have to spend time in a remote area where other water is not readily available. But a major part of the problem is the extent to which it is used unnecessarily in many peoples' day-to-day activities. |
I did some work on this for a UK organisation called wewanttap.
The carbon footprint of bottled water is quite significant - half a gram or so per millilitre - depending on where it has been shipped from and the source of the primary energy used in electrcally powered injection blow moulding manufacturing of the bottle.
