During the past half-century, atrazine has become one of the most widely used herbicides in Minnesota and the Midwest. Unfortunately, it is also at the top of the list in another category: most commonly detected pesticide in our state’s surface and groundwater. Atrazine contamination has been found in agricultural communities from southeast Minnesota to the Boundary Waters Canoe Area Wilderness. That’s a concern when one considers there is an increasing body of science showing that exposure to the herbicide, at even extremely low levels, pose significant health risks to humans and animals. That’s why it is so key that the Environmental Protection Agency’s current review of atrazine’s safety be based on science and what’s good for the public.
