Despite an intensely green image, Fiji water is among the least environmentally and socially conscious waters on the planet. All bottled water is bad, especially in areas like the U.S. that have potable and frequently tested tap water. Note that water brands that are actually pure spring water are not required to test their quality at all, though most do at far lower frequencies than public tap water is tested.
Still, Fiji water has remained immune to the outpouring (so to speak) of attention that at least the environmentalists are giving to the issue of bottled water with all of its plastic waste and CO2 emissions from trucking it around the country (or worse, shipping it halfway around the world).
