Atrazine, one of the most commonly used pesticides on crops ranging from corn to trees, may not be as dangerous to humans as previously thought.
In a July 22, 2001, story, Columbia Missourian reporter Lori Luechtefeld (573-882-5720) broke the news that the EPA is considering upping acceptable levels of the chemical in drinking water by as much as 400% based on new research findings. EPA is currently reassessing thecarcinogenicity and toxicity of atrazine , the second most common pesticide found in private and community wells.
Many states have taken substantial steps to require farmers to change their practices to minimize drinking-water contamination. For instance, WI prohibits the chemical's use in certain parts of the state.
