The Environmental Protection Agency has warned residents to stay away from a river in Colorado after accidentally spilling around a million gallons of mine waste water into it.
Local residents were advised to cut back on water use and keep away from the contaminated river until the all clear was given by officials.
The spill in a river in southwest Colorado on Thursday which turned the river orange was, ironically, caused by a federal mine cleanup crew.
The Huffington Post reports:
The U.S. Environmental Protection Agency said that a cleanup team was working with heavy equipment Wednesday to secure an entrance to the Gold King Mine. Workers instead released an estimated 1 million gallons of mine waste into Cement Creek.
“The project was intended to pump and treat the water and reduce metals pollution flowing out of the mine,” agency spokesman Rich Mylott said in a statement.
The creek runs into the Animas River, which then flows into the San Juan River in New Mexico and joins the Colorado River in Utah.
Officials emphasized that there was no threat to drinking water from the spill. But downstream water agencies were warned to avoid Animas water until the plume passes, said David Ostrander, director of EPA’s emergency response program in Denver.
Officials weren’t sure how long it would take the plume to dissipate, Ostrander said. The acidic sludge is made of heavy metal and soil, which could irritate the skin, he said.
The EPA was testing the plume to see which metals were released. Previous contamination from the mine sent iron, aluminum, cadmium, zinc and copper into the water, said Peter Butler, co-coordinator of the Animas River Stakeholders Group.
Earlier Thursday, the EPA said in a statement that the polluted water “was held behind unconsolidated debris near an abandoned mine portal.”
The plume made its way to Durango on Thursday afternoon, prompting La Plata County health officials to warn rafters and others to avoid the water. The scenic waterway was the backdrop for parts of the movie “Butch Cassidy and the Sundance Kid” and is popular with summer boaters.
Durango stopped pumping water out of the Animas River on Wednesday to make sure none of the waste could be sucked up into the city reservoir. It also suspended the transfers of raw water to a local golf course and Fort Lewis College. Pet owners were advised to keep dogs and livestock out of the Animas.
“It’s really, really ugly,” Butch Knowlton, La Plata County’s director of emergency preparedness, told The Durango Herald (http://bit.ly/1NcOaJZ). “Any kind of recreational activity on the river needs to be suspended.”
In Farmington, New Mexico, city officials shut down water-supply intake pumps to avoid contamination and advised citizens to stay out of the river until the discoloration has passed. Don Cooper, emergency manager in San Juan County, said people should not panic because the EPA had told the county the spill would not harm people and that the primary pollutants were iron and zinc.
“It’s not going to look pretty, but it’s not a killer,” Cooper told The (Farmington) Daily Times (http://bit.ly/1SVScNN).
The impact on wildlife wasn’t clear. There are no fish in the Cement Creek watershed because of longstanding problems with water quality, the Colorado Department of Public Health and the Environment said.
Colorado Parks and Wildlife was placing cages containing fish in the Animas River to monitor what happens to them, spokesman Joe Lewandowski said.
“We’ll see if those fish survive,” Lewandowski said. “We’re also monitoring to make sure we don’t get infiltration into the hatchery, because that could be a problem.”
The U.S. Fish & Wildlife office in suburban Denver did not immediately return a call asking about the spill.
