In a August 10 USA Today article, it is reported, ” EPA: Pollution from mine spill much worse than feared” – with the spill being three times (3 million gallons) what was first reported.

USAtodaySpill“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.” – USA Today

From KOAT TV 7 – Alberque:  

DENVER —A mine spill in Colorado that filled the Animas River with mustard-colored muck has reached Farmington and parts of the Navajo Nation.

animasrivercoloradoFederal environmental officials said the muck that surged into the river from the mine contained heavy metals, including lead and arsenic, but they didn’t immediately discuss amounts or health risks.

The Environmental Protection Agency said the spill also contained cadmium, aluminum, copper and calcium.

EPA Regional Director Shaun McGrath did not mention whether the elements posed a health hazard, but he said local authorities were right to close the Animas River to human activities.

An EPA crew accidentally unleashed 1 million gallons of wastewater from the mine Wednesday that flowed into the river through a tributary.

McGrath says the crew was trying to treat draining waste at the abandoned Gold King Mine in Southwestern Colorado when the workers inadvertently unplugged the waste.

Gov. Susana Martinez toured the contaminated river on Saturday and bashed EPA officials for not warning the state about the spill promptly.

Officials from New Mexico’s Environmental Health Department say they didn’t hear about the spill until Action 7 News started asking questions, and that an EPA official didn’t call them at least 24 hours after the spill.

McGrath says the EPA is taking full responsibility for the blunder.

“We misjudged, and this is something that I’m owning up to,” McGrath said. “The message was a day delayed and we do apologize for that.”

Officials are still waiting on samples from the contaminated water to see what effects it could have on wildlife or people.

Right now, McGrath says the EPA doesn’t even know what’s exactly in the plume and are awaiting to see if toxic materials such as arsenic or lead are even in it.

If they are, McGrath says the EPA will have to monitor the river for the foreseeable future. The materials could possibly float to the bottom of the river and get flushed back up when it rains, according to McGrath.

McGrath has said no personnel have been disciplined as a result of the spill.

He says there were four crew members present at the time of the spill and that most of them were contracted employees while the EPA supervised and gave direction.

The Animas River is popular with boaters and anglers and runs into New Mexico.

Farmington officials warned residents who use wells in the floodplain of the Animas and San Juan rivers to avoid using their wells for drinking, cooking or bathing until tests have been completed.

Those who are unclear of the location of their wells or the floodplain can find maps at the San Juan County Emergency Operations website.
