State of Emergency Declared After Mine Spill in Colorado Pollutes Animas River

Officials from the Environmental Protection Agency said Sunday that the Gold King Mine discharged an estimated 3 million gallons of contaminated water, three times the amount previously believed.

The mine continues to discharge 500 gallons per minute, EPA Region 8 administrator Shaun McGrath said in a teleconference call Sunday afternoon, but the polluted water is being contained and treated in two ponds by the site of the spill near Silverton, Colo.

According to preliminary testing data the EPA released Sunday, arsenic levels in the Durango area of the Animas River were, at their peak, 300 times the normal level, and lead was 3,500 times the normal level. Officials said those levels have dropped significantly since the plume moved through the area.

Both metals pose a significant danger to humans at high levels of concentration.

“Yes, those numbers are high and they seem scary,” said Deborah McKean, chief of the Region 8 Toxicology and Human Health and Risk Assessment. “But it’s not just a matter of toxicity of the chemicals, it’s a matter of exposure.”

She said the period of time those concentrations remain in one area is short.

Earlier Sunday the city of Durango, Colo., and La Plata County, Colo., declared a state of emergency. The Navajo Nation Commission on Emergency Management also issued a state of emergency declaration in response to the spill.

EPA officials said in the teleconference Sunday afternoon that water quality experts have been deployed to Shiprock and are encouraging people there to take advantage of water quality sampling.

EPA officials said they are also working to provide necessary materials to people in Farmington and Aztec for private well sampling.

New Mexico Environment Department spokeswoman Allison Scott-Majure said testing has not yet been performed in San Juan County.

In San Juan County, restrictions are still in effect along the Animas River, said County Executive Officer Kim Carpenter. The biggest obstacle, he said, is making sure residents and livestock have access to drinking water.

Access to the Animas River is still closed throughout the county, and officials advise residents with wells in floodplains to have their water tested before drinking it or bathing in it.

Carpenter said people and their pets should avoid contact with the river, livestock should not be allowed to drink the water and people should not catch fish in the river. He also instructed people to avoid contact with the wildlife along the river in Berg Park, as information on the chemicals in the water is still being released.

In Sunday’s teleconference, McGrath said the EPA is looking at the next steps for cleaning up the site.

“We’re working to see if we can get this on the National Priorities List for designation as a SuperFund cleanup site,” McGrath said.

He qualified the statement a moment later, saying, “It’s one option that can be considered.”

According to the EPA’s website for the Upper Animas Mining District, environmental officials considered adding the Upper Cement Creek area to the National Priorities List in 2008, but decided against it due to a lack of community support.
