At least 3,000 geese killed by toxic water from former Montana copper mine

Incident raises questions about how Trump's administration would the country's largest Superfund site from leaking its poisonous mix into other waters

At least 3,000 geese were killed by a toxic stew formed by a former copper mine in Butte, Montana, this weekend, raising questions about how the new Trump administration will handle the largest Superfund site in the country.

Over the weekend, a large flock of geese making a late migration over Montana was blown off course by a snowstorm, which sent the birds toward the abandoned copper mine. They splashed down into the 50bn-gallon pool, polluted heavily by acidic chemicals and metals, and died en masse.
