BP, the same company that brought you Deepwater Horizon, is open to suggestions of how to prevent the tragedy from occurring again. Efforts to frighten the goose off the pit with sound and a battery powered, remote controlled boat with a scary face failed in the harsh cold. Predictably, a resort to more technology--lasers--is being considered. Apparently cleaning up the mess is too expensive for Anaconda Company which began consuming the mountain of copper ore called the "richest hill on Earth" in 1955, creating the 1780 foot deep, Berkeley Pit. ARCO bought the property from Anaconda in 1977 and allowed the pit to fill with water since mining operations had ceased on a large scale. The water is acidic as vinegar and filled with toxins. It is part of a Superfund site which so far has cost $2 billion to remediate.
The pit is not going to go away; it has become something of a local tourist attraction, but BP will have to start pumping out the bad water and treating it before it reaches Butte's groundwater supply estimated to occur by 2023. Local officials believe the previous mass death of geese at the pit in 1995 should have been an alarm bell signaling action. But when money is involved and corporate profits at stake, NOT.
