Atrazine weed-killer in US drinking water supply

See also the Huffington Post, EPA fails to inform public about weed-killer in drinking water

...and DemocracyNow's coverage of the story.

Atrazine is the most commonly detected pesticide in groundwater and surface water.

The Pesticide Info Database maintained by the Pesticide Action Network identifies atrazine as a carcinogen, suspected endocrine disruptor, and posing a very high risk for groundwater contamination. For these reasons they classify the herbicide as a "Bad Actor." See the Pesticide Info entry for atrazine for more information about its ecological and human health effects.

Now this is why I read "Busy, busy, busy."

Glad you're back.

When using Atrazine products, farmers in the United States are turning more to conservation tillage and no-till systems. In 2008, atrazine was applied to more than 60 percent of conservation tillage and no-till corn acres.

Atrazine is the single most widely used herbicide in sweet corn, applied to fields before crop emergence, after crop emergence, or at both times. Manufacturers of many of the other herbicides recommend tank-mixing with atrazine to increase their products' effectiveness.

Thomas said...

Life without Atrazine would complicate weed management in corn, especially for sweet corn growers. A study at the University of Illinois looked at 175 sweet corn fields in the Midwest to find out just how important this 50-year-old, broad-spectrum herbicide is in sweet corn grown for processing.
