EPA Mulls Loosening Limits on Atrazine in Drinking Water

August 8, 2001


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.
