L'eau de Paris...(22/3)

...Paris city authorities began distributing thousands of specially-designed glass carafes in a campaign to wean the public off bottled mineral water and back onto the tap. A poll showed that 51%...
of the two million Parisians buy their drinking water in shops (including me, haha), and the city hall and publicly-owned water company Eau de Paris argue that the piped alternative is cheaper, more ecologically sound, and just as healthy. Hundreds joined a long queue at the esplanade in front of the Hotel de Ville where Parisians could present a coupon downloaded from the Internet or cut from a local newspaper in return for a carafe marked with the Eau de Paris logo and an Eiffel Tower...

This is not just a matter of marketing exercise for the Water Authority, but it's more a concern of the water quality and pollution of which the Parisians may have developed this drinking habit accordingly. My office, like many others, distributes bottles of drinking water and people do not drink too much tap water. A not-too-unobvious fact in Paris is that the tap water contains high percentage of calcium, and to a certain extent, I see much a feeling of insecurity to try a taste of the running water. On the other hand, I admire a lot the packaging, the quality and the distribution efficiency of the bottle water in supermarkets and restaurants, not just only the brand of Perrier or Evian or Vittel. Sparkling water, an invention I am not sure if it's also from France...(let me know if you have any idea), is another element that adds a favour to the gourmet of French cuisine. Because of the extra cost, I have a feeling that Parisians do not really drink a lot, at least not in the restaurants (excluding their red or white wine just like their own "d'eau mineral"). So how much do you know about the water you are drinking of?
