Federal officials say a waste-water spill in a Colorado river is in the process of being cleaned, but should pose no threat to wildlife in the meantime.

FOX News Radio's Gurnal Scott reports:

The murky orange color of the water in the Animas River comes from three million gallons of metal-laced mine water -- much more than the original one million gallon estimate. New Mexico Governor Susana Martinez called it a disturbing sight.

(Martinez) "It's like when I flew over the fires. You see something that your mind isn't ready or adjusted to see."

EPA work to pump contaminated water out of the mine led to the accidental release.

Colorado and New Mexico towns have been considering alternative water sources. The EPA says the quick-moving spill prompted a meeting with residents living down-stream where water samples are still being analyzed.
