Nice one Eddie - here goes.
Much of the bottled water you buy is taken from boreholes, springs and river sources, not from the point where rivers run into the sea.
Anyone who tampers and robs groundwater sources eventually causes rivers to run dry. Look at what has happened to the classic chalk streams of Hertfordshire for example.
One of the incredible things about some bottled water is that it is not what you think it is. It's tap water that has been filtered, with minerals and CO2 added in some cases.
If you want nice tasting water free of chlorine, taste, odour, pesticides, certain heavy metals, herbices and toxic sheep dips, consider fitting a filter on your drinking water.
These are very low cost to fit and for the average family it will only cost you about ?25 a year for replacement cartridges. which will process up to 160,000 litres of water.
MOST households have these filters in the USA by the way, as well as filters on the fridges. You can have a supply of chilled water that tastes better than bottled water and you are not removing water from natural springs.
Bottled water is BAD, if you are an environmentalist.
