Britons are wasting £2 billion a year on bottled water when the kitchen tap provides a safe alternative…a BBC Panorama programme will claim on Monday night…The environment minister, Phil Woolas, tells the programme it is also a moral issue that bottled water is being sent to Britain when many countries have no access to safe drinking water…The environmental cost of bottled water is also high. A litre of one of the leading French mineral waters generates up to 600 times more carbon dioxide than a litre of Thames tap water…But a spokesman for the bottled water industry said Mr Woolas was "ill informed".
