The head of the U.S. Environmental Protection Agency, Gina McCarthy, was in Seattle this week. She delivered the keynote address at a Climate Leadership Conference Wednesday night.

But beforehand, she also spoke to students and faculty at the University of Washington’s schools of public health and public policy. She talked about her concerns in the wake of the crisis in Flint, Michigan, where lead has been poisoning municipal water supplies.

She said at its heart, more than anything, this crisis is about money.

She’s been called President Obama’s “green quarterback.” Gina McCarthy is the head of the Environmental Protection Agency, and she's known for tackling sources of climate change. And now she’s shining a light on efforts to clean up Puget Sound.

McCarthy met with government officials and community groups in Tacoma on Wednesday and toured Commencement Bay by boat to learn more about what still needs to be done.
