EPA Weakens Water Quality Standard for Harmful Selenium

WASHINGTON - The Environmental Protection Agency finalized nationwide water-quality criteria for selenium today that are substantially weaker than proposed standards issued nearly six years ago. The EPA ignored the recommendations and concerns of the U.S. Fish and Wildlife Service and National Marine Fisheries Service regarding what levels of selenium pollution would be harmful to endangered species. Although selenium is beneficial to human health in very small doses, this metal becomes toxic as it accumulates in larger and larger amounts through the food chain.
