"A study released on Thursday finds that 39 sites in 21 states where coal-fired power plants dump their coal ash are contaminating water with toxic metals such as arsenic and other pollutants, and that the problem is more extensive than previously estimated.

The analysis of state pollution data by the Environmental Integrity Project, the Sierra Club and Earthjustice comes as the Environmental Protection Agency is considering whether to impose federally enforceable regulations for the first time. An alternative option would leave regulation of coal ash disposal up to the states, as it is now.

The EPA will hold the first of seven nationwide hearings about the proposed regulation Monday in Arlington, Va. A public comment period ends Nov. 19."
