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.
