The spill which sent toxic waste from an abandoned mine into a Colorado waterway last week released three million gallons of contaminates into the state's 126-mile Animas River—not one million, as previously announced, according to new estimates by the Environmental Protection Agency (EPA).
As the orange-hued sludge kept flowing through Colorado and into the San Juan River in New Mexico on Monday, the fallout from the massive accident continued to spread, with communities declaring states of emergency and the Navajo Nation vowing to take action against the EPA, which caused the spill.
The county of La Plata and the city of Durango, both in Colorado, each declared a state of emergency at noon on Sunday.
La Plata County manager Joe Kerby said in a statement: "This action has been taken due to the serious nature of the incident and to convey the grave concerns that local elected officials have to ensure that all appropriate levels of state and federal resources are brought to bear to assist our community not only in actively managing this tragic incident but also to recover from it."
Water quality tests along the rivers were still being conducted as of Monday afternoon. According to preliminary data released by the EPA on Sunday, arsenic levels in the Durango area were, at their peak, 300 times higher than normal. Lead was 3,500 times higher than normal. The waste also includes copper, zinc, aluminum, and cadmium.
Meanwhile, the mine continues to discharge at 500 gallons per minute. Although the EPA maintains that the waste is unlikely to have harmed wildlife in the area, local officials in affected areas have advised residents not to use the river for agricultural or recreational purposes or to allow their pets to drink the water.
The Navajo Nation Commission on Emergency Management also declared a state of emergency. During a meeting Saturday at the Shiprock Chapter House in Shiprock, New Mexico, Navajo Nation president Russell Begaye said he intends to take legal action against the EPA for causing the spill.
"The EPA was right in the middle of the disaster and we intend to make sure the Navajo Nation recovers every dollar it spends cleaning up this mess and every dollar it loses as a result of injuries to our precious Navajo natural resources," Begaye told those in attendance.
"I have instructed Navajo Nation Department of Justice to take immediate action against the EPA to the fullest extent of the law to protect Navajo families and resources," he said. "They're not going to get away with this."
New Mexico Governor Susana Martinez visited a portion of the contaminated river in Farmington over the weekend. "The magnitude of it, you can't even describe it," she said of the scene.
Climate activists with Peaceful Uprising on Monday also staged a protest in Utah that connected the spill to the larger issues of fossil fuel mining and the environmental harm such activities cause. Several activists blockaded a Book Cliffs tar sands mine, owned by Calgary-based US Oil Sands, which they say operates on land that rightfully belongs to Indigenous people and risks poisoning the surrounding environment with a similar spill.
"Thousands of mines like open wounds tell the story of a century of exploitation, destruction and violence—against the people of this land and the land and water themselves," said Melanie Martin, an activist with Peaceful Uprising. "US Oil Sands continues that sick tradition by squandering precious water in a thirsty region and saddling future generations with a toxic legacy there is no way to clean up."
The orange wastewater, still flowing downriver, is currently heading toward Utah, where the San Juan River joins Lake Powell. In preparation, officials in the town of Montezuma Creek have shut off water pumps there and in nearby Aneth, parking a 7,000-gallon tanker of potable water at a Montezuma Creek fire station.
The accident occurred last Wednesday after EPA workers attempting to investigate heavy metal waste at the abandoned Gold King Mine in Colorado accidentally unleashed the toxic materials into the Cement Creek, which feeds the Animas River. As Common Dreams reported on Sunday, cleanup of non-functioning mines in the U.S. has long been hampered by legal and financial roadblocks.
