The water of the Cement Creek flows down a valley a few miles downstream from the Gold King Mine, where a wastewater accident several days earlier has raised alarm, outside Silverton, Colo., Wednesday, Aug. 12, 2015.

The Navajo Nation on Tuesday joined New Mexico in pursuing legal action against the U.S. Environmental Protection Agency in the wake of the August 2015 spill in southwestern Colorado.
