Sierra Club offered the free mercury testing to highlight the fact that mercury is emitted from coal fire power plants. The environmental group is backing the EPA's new proposed regulations that would limit mercury and other air toxins from coal-fired power plants.

A spokesperson for the GenOn plant says the company is evaluating the proposed changes and may have to make further investments in pollution controls to meet the regulations.
Alexandria resident Heather Schaffer came for the test because she's concerned about living close to the GenOn plant and wants to find out how much mercury is in her body.
