spring water

The lawsuit against Arrowhead bottled water, advertised as "100 percent mountain spring water," argues that it's the "100 percent" that's deceptive.

It traces what happens when two Tokyo outsiders descend on a pastoral area where the spring water is so pure a local noodle shop uses it in its food preparation.

Meanwhile, winter snowfall is declining as the region warms, threatening spring water supplies.

Fresh spring water is natural, sure, but so is uranium, arsenic and cyanide.

It is a common custom to place the purest spring water in bowls as a sacred offering in a home or a temple.
