Toxic mine outflow spill in Colorado

Is anybody else following this?:

Animas River: EPA's Colorado mine disaster plume flows west toward Grand Canyon

Quote:

SILVERTON — Three days after EPA workers triggered a huge blowout at a festering mine in southwestern Colorado, a mustard-colored plume — still fed by 548 gallons leaking per minute — stretched more than 100 miles, spreading contaminants including cadmium, arsenic, copper, lead and zinc.

What can be done? Is this as bad as it seems?

(I put this in the Science the Tech forum, as I am more interested in the impacts of the spill and possible mitigation, rather than laying fault on one party or another.)
