Black Warrior Riverkeeper and Waterkeeper Alliance have teamed up with Greenpeace and the University of North Carolina to offer you the opportunity to test your mercury levels.

Why would I want to know my mercury level?

Mercury is highly toxic heavy metal that contaminates a third of our nation’s lakes, a quarter of our rivers, and many of the fish that we eat. Mercury ends up in the tissues of commonly eaten fish like tuna and bass and threatens the health of millions of people across the United States. Humans, at the top of the food chain, can consume enough mercury to put them at risk of neurological, circulatory and immune system disorders. EPA and the Centers for Disease Control estimate that 630,000 children are born every year with unsafe levels of mercury in their blood.
