Mercury Contamination Is Nationwide
More than two-thirds of fish tested by the federal government between 1998 and 2005 are contaminated by mercury at levels exceeding EPA standards according to a recent report.
Contamination is widespread, the report said, coming from various sources depending on geography. Coal-fired power plants are the largest source of mercury, although 59 of the 291 streams studied may have been affected by gold and mercury mining. The highest mercury levels were found in the south and southeast-North and South Carolina, Georgia, Florida and Louisiana, while elevated levels were found in mining areas of the West and watersheds in the Northeast and Upper Midwest.
In 2008, Earthjustice successfully appealed an EPA rule favorable to industry which would have allowed dangerous levels of mercury to persist. We’re waiting for the Obama administration to make good on its promise to introduce new power plant emission regulations.
