Cleanup method uses activated carbons to anchor toxins to bottom of the bay

Imagine a Brita filter big enough to clean up San Francisco Bay. Richard Luthy, chair of Stanford's Department of Civil and Environmental Engineering, has a plan to clean polluted sediment at Hunters Point in San Francisco with activated carbon—the same technology in many water filters. Luthy proposes to sequester dangerous toxins by mixing activated carbon, a type of carbon with a large surface area, into the bay's contaminated sediment.
