The U.S. federal standards for acceptable levels of pharmaceutical residue in bottled water are the same as those for tap water — there aren’t any.
The Food and Drug Administration, which regulates the $12 billion bottled water industry in the United States, sets limits for chemicals, bacteria and radiation, but doesn’t address pharmaceuticals.
Some water that’s bottled comes from pristine, often underground rural sources; other brands have a source no more remote than local tap water. Either way, bottlers insist their products are safe and say they generally clean the water with advanced treatments, though not explicitly for pharmaceuticals.
Nestle Waters North America Inc., an industry leader whose brands include Arrowhead, Poland Springs and Ozarka, said it selects sources that are removed from human activity, increasing the chances that the water will be pure. It then runs the water through three cleansing stages.
“We know that our multiple barrier process is effective,” said Kevin Mathews, the company’s director of health and environmental affairs.
