Michelle Obama's toxic veggie nightmare: White House organic garden polluted with sludge

When First Lady Michelle Obama planted an organic vegetable garden on the White House lawn in March 2009, she hoped to both set an example of healthy eating and to grow tasty edibles for her daughters and husband. But Michelle's organic dream has been dashed by a nasty toxic legacy lurking in the soils of 1600 Pennsylvania Avenue. It turns out that a previous Presidential gardening team had used sewage sludge for fertilizer.

This is a fairly common practice with one huge problem. Sewage sludge tends to be laced with anything that people pour down the drain and often contains heavy metals. Not surprisingly, the National Park Service tested the dirt beneath Michelle's garden and found the plot has highly elevated levels of lead averaging 93 parts per million. That's below the 400 ppm that the Environmental Protection Agency says is a threat to human health. But I'd wager that Sasha, Malia and Barack won't be getting arugula or tomatoes from this garden any time soon.
