Toxic Sludge Taints the White House

When First Lady Michelle Obama decided to plant a vegetable garden at the White House, she faced a problem that many new homeowners in America run into. Previous residents of her house had applied sewage sludge to her lawn, but left no warnings to alert the her about the potential toxicity of her soil as a result of the sludge application. When the Obamas tested the soil in preparation for planting their garden, they found some lead in the soil. At 93 parts per million (ppm), the lead showed that the soil was probably contaminated by something, even though at 93 ppm the lead itself was not necessarily a danger. Still, the Obamas took precautions to further lower the lead level to 14ppm, and make the lead unavailable to plants by adding soil amendments that diluted the lead and changed the pH of the soil.

Sludge Politicized

Unfortunately for the Obamas, and for the entire nation, once the story hit the news, it became politicized. While the issue was initially raised as a comment on the safety of using sewage sludge as fertilizer – an issue that has no political party – the right soon grabbed a hold of the story as a way to make fun of the Obamas. Some on the left fiercely defended the Obamas in return. But the Obamas are not the villains in this story; they are the victims. They are among many other Americans whose yards and gardens are contaminated with sewage sludge without their knowledge and who, as a result, are exposed to toxic contaminants in the soil. And lead is just a fraction of the overall problem.

Waiter, There Is Toxic Sludge in my Organic Soup!

Fifteen years ago, the Center for Media and Democracy in my book Toxic Sludge Is Good for You first exposed the deceptive PR campaign by the municipal sewage industry that has renamed toxic sewage sludge as "biosolids" to be spread on farms and gardens. Unfortunately, the scam continues to fool more people than ever, even in San Francisco which is often dubbed the country's greenest city.

I suspect that Bay area celebrity chef Alice Waters would never dump sewage sludge onto her own organic garden, nor serve food grown in sludge in her world famous natural foods restaurant Chez Panisse. The mission of her Chez Panisse Foundation is to create "edible schoolyards" where kids grow, prepare, and eat food from their own organic gardens. But Francesca Vietor, the new executive director of the Chez Panisse Foundation, is at the same time actively promoting dumping toxic sludge on gardens in her role as Vice President of the San Francisco Public Utilities Commission.

Food Marketers Try "Local-washing"

"The ingenuity of the food manufacturers and marketers never ceases to amaze me," remarked author Michael Pollan. "They can turn any critique into a new way to sell food." Marketers are appropriating language from the "eat local" or "locavore" movement, which encourages support for small farms, sustainable practices and better treatment of animals.

Europe Backpedals on Biofuels

Ear of corn on stalkThe European Union (EU) has drastically changed its course for the future of biofuels. Until this week, the EU planned to be the world leader in using biofuels as an alternative to petroleum-based fuel, aiming for 10% of transportation fuels to be derived from biofuels by 2020.
