A new University of Washington study that tested 65 wines from America’s top four wine-producing states — California, Washington, New York and Oregon — found all but one have arsenic levels that exceed what’s allowed in drinking water.The U.S. Environmental Protection Agency allows drinking water to contain no more than 10 parts per billion of arsenic. The wine samples ranged from 10 to 76 parts per billion, with an average of 24 parts per billion.
