Taylor and Gabe love the water, but they know that keeping it clean is not always easy. Just upriver in Palmerton, Pennsylvania, there is an old zinc smelting plant that was one of the factories polluting the local rivers and streams.

Their question: Can nano-iron clean up the pollution in soil and prevent it from getting into drinking water?
