Mercury pollution from power plants cut by 90%.

Iowa's power plants will release 90 percent less mercury pollution into our air and water under new EPA standards we supported—great news for Iowa's families, given mercury's toxic effects on how our kids think, learn and behave. Together with our national coalition, we helped mobilize more than 800,000 people across America to contact the EPA in support of safer emissions standards—no other EPA rule has ever received so much support.
