An analysis found that yearly average levels of atrazine in drinking water violated the federal standard at least ten times in communities in Illinois, Indiana, Ohio, and Kansas, all states where farmers rely heavily on the herbicide.In addition, more than 40 water systems in those states showed spikes in atrazine levels that normally would have triggered automatic notification of customers. In none of those cases were residents alerted.In interviews, EPA officials did not dispute the data but said they do not consider atrazine a health hazard and said they did not believe the agency or state authorities had failed to properly inform the public. "We have concluded that atrazine does not cause adverse effects to humans or the environment," said Steve Bradbury, deputy office director of the EPA's Office of Pesticide Programs.Officials at Syngenta, the Swiss company that manufactures atrazine, declined requests for interviews about the testing results. In a statement on its Web site, the company says that atrazine "poses no threat to the safety of our drinking water supplies. In 2008, none of the 122 Community Water Systems monitored in 10 states exceeded the federal standards set for atrazine in drinking water or raw water."Atrazine has become an issue of concern for environmentalists and consumer groups as the use of the herbicide has soared in the United States over the past few decades. Some scientists who have studied atrazine said the information about its higher levels in drinking water should be made public.For more background on the story of atrazine, watch our video: "How Safe Is Atrazine?”
