text: WATER fountain season is here. New York City workers have turned on bubblers in the parks, and the Icelandic artist Olafur Eliasson has begun to erect four enormous waterfalls in the harbor, each 90 to 120 feet high, that are scheduled to flow from July to October. The shimmering cascades will cost the city nothing (the $15 million cost is being paid by private donations to the Public Art Fund), but here’s a better idea for a civic-minded organization or person interested in celebrating water: sidewalk fountains in places outside the parks.
  
  Convenience is said to be one of bottled water’s greatest allures: we’re a grab-and-go society, consuming roughly 50 billion bottles of water a year. But as awareness of the product’s economic and environmental impact has escalated, mayors across the nation (although not Michael Bloomberg of New York) have canceled city contracts with bottled water purveyors, citing the expense of hauling away empties (less than 20 percent make it into recycling systems); the vast amounts of oil used in producing, transporting and refrigerating the bottles; and the hypocrisy of spending taxpayer dollars on private water while touting the virtues of public supplies. Last summer, New York City spent $700,000 on a campaign reminding New Yorkers that their tap water is tasty and affordable.
  
  Delivered by gravity, tap water generates virtually no waste. All that, and it contains no calories, caffeine or colorants either. (Yes, New York’s water — like that of other cities — contains trace amounts of drugs, but we lack proof, so far, that exposure at these low levels is a human health risk.)
  
  Bottled water’s main virtue, it seems, is convenience, especially for people at large in the city. As the editor of Beverage Digest told The Times, “It’s not so easy, walking down Third Avenue on a hot day, to get a glass of tap water.”
  
  But it needn’t be so. Paris has its ornate cast-iron Wallace fountains (donated in the late 19th century by a wealthy philanthropist hoping to steer the homeless from alcohol toward a healthier beverage); Rome its ever-running street spigots; Portland, Ore., its delightful four-bowl Benson Bubblers.
summary: An entire generation of Americans has grown up thinking public faucets equal filth. It’s time to change that perception with public fountains.
