It would be nice to have a history of this pit, for instance, how it got its name. Tmangray 06:11, 19 December 2006 (UTC)
What's up with the MR acronym in the timeline? What does MR stand for? Always introduce acronyms.
I can't find an explanation of WHY the mine was closed anywhere. Is this known? Why did ARCO buy it only to close it down shortly after? Matthew Brown (Morven) ( T: C) 10:06, 4 March 2006 (UTC)
They just stop mining it. They no longer needed the spot, nor did they want to continue pumping out the water that was constantly coming in. -- 69.145.122.209 23:12, 3 April 2006 (UTC)
ARCO intended to use the loss as a write-off against gigantic profits garnered from the manufactured oil crisis of the mid-1970s. ARCO purchased the Anaconda company for the loss the company sustained from Chile nationalizing its assets there. Anaconda could not sustain that financial blow and a significant plant failure in the town of Anaconda. The company had intended to increase production, but a freeze caused substantial damage to the plant in Anaconda. The cost of labor also played into the decision to close the mine and cease production.
This article is one of thousands on Wikipedia that have a link to YouTube in it. Based on the External links policy, most of these should probably be removed. I'm putting this message here, on this talk page, to request the regular editors take a look at the link and make sure it doesn't violate policy. In short: 1. 99% of the time YouTube should not be used as a source. 2. We must not link to material that violates someones copyright. If you are not sure if the link on this article should be removed or you would like to help spread this message contact us on this page. Thanks, --- J.S ( t| c) 04:04, 10 November 2006 (UTC)
Can the reference to the largest superfund site be verified, deleted or qualified. Tar Creek in Oklahoma also claims itself as the largest superfund site, encompassing 50 sq miles. The closest I've found is : http://www.usdoj.gov/opa/pr/2002/March/02_enrd_180.htm which indicates it is the superfund site with the largest body of contaminated water in the United States. However, as the Hudson River is also making that claim about a 200 mile stretch from Hudson Falls to the Battery, even this is a dubious claim. Bangfrog 22:01, 23 November 2006 (UTC)
It's my understanding that the pumps keeping the mine dry were in the nearby Kelley mine, an underground mine. Sounds picky, but just from the article one might assume that the pumps were in the Pit itself. This kind of thing can probably be verified by checking old articles in the Montana Standard (not an easy thing come by in LA, or I'd do it). BSMet94 20:16, 4 January 2007 (UTC)

Is there a reference for who actually attempted "mining" the water from the Berkeley Pit? The article seems to suggest that someone was commercially trying to recover copper from the pit water. Playing with it in a lab is quite different than setting up a commercial operation. Furthermore, there was in fact failed commercial venture where someone actually built an ion exchange plant at the Kelley Mine and attempted to recover zinc oxide from the Kelley Mine water, but that's different. The chemistry in the Kelley mine water is much different than the pit. There's more dissolved iron in the pit water than any other metal. Despite it having formerly been a copper mine, there's relatively little copper in the pit water. Anyway, unless there's a reference for "mining" the pit for copper, then that bit should be deleted.

They are actually doing it. From "Pitwatch", the local Butte newsletter about the pit:
Q: Is Montana Resources "mining" the Berkeley Pit water?
A: Yes. The company is still recovering copper from the water in the Berkeley Pit.
Since February 2004, 13 million gallons of water per day are being pumped out of the Berkeley Pit and up to the precipitation plant. The water is collected at a depth of 150 feet from the far west side of the Pit below the viewing stand, and is pumped up and around the south and east walls of the Pit to the precipitation plant, north east of the Pit.
The "Precip Plant" uses a centuries-old technology operation where water flows through piles of recycled scrap iron. The process is known as "cementation." It occurs when copper-containing water flows into cells filled with scrap iron. The iron in the cells and the copper in the water trade places. The iron-rich water is returned to the Pit. The product, containing about 70% copper, is dried through a filter press and then sent to an off-site smelter.-- Banjodog ( talk) 02:46, 30 December 2007 (UTC)
I'm not interested in fighting about it, but I was putting them in chronological order, I thought. The first paragraph deals with the beginning and first years of the pit; the communities were taken out in the 60s and 70s. Cheers Geologyguy 19:02, 15 May 2007 (UTC)
The source used as a reference for "Berkeley Acid" uses the name "Berkelic Acid" instead.
