Erin Brockovich Calls Out EPA After Gold King Spill

Environmental activist Erin Brockovich is accusing the U.S. Environmental Protection Agency of not telling the truth about the amount of wastewater that fouled rivers in three states after spilling from a Colorado mine.

She leveled the accusation against the agency during a visit to the Navajo Nation on Tuesday. She met with tribal leadership and farmers affected by last month's spill and spoke to a crowd of high school students in Shiprock, New Mexico.

During her speech, Brockovich questioned the EPA's estimate that 3 million gallons spilled from the Gold King Mine near Silverton, Colorado.

The agency did not immediately respond to requests for comment.
