"Selenium From Power Plants Poses Ecological Risks, Spurs EPA Review"

"Selenium is an essential nutrient, but excess amounts can be dangerous to wildlife and people. Now the U.S. Environmental Protection Agency is preparing a new regulation that would require more than 600 coal-fired power plants to clean up -- perhaps even eliminate -- wastewater discharged into lakes, rivers and other waterways. The national standards would replace a patchwork of state regulations that EPA officials say are too lax to protect fish and wildlife from toxic metals and other elements, particularly selenium, in the plants' wastewater.
