Talk:Acid mine drainage

message: The List of AMD sites is getting quite lengthy.  As the article notes, there are thousands of such sites.  We should limit the list to sites with wiki articles or citations documenting the AMD problem.  Plazak (talk) 11:56, 15 August 2009 (UTC)
replies: text: Without effort, I could double the present list by sitting down and writing for a half-hour. Even doubling the entries would only present but a fraction of the known sites generating acid drainage. It's probably best to list only a few high profile cases (e.g., Iron Mountain or Berkeley Pit or Wheal Jane) and otherwise refer to the best estimated number of sites in a given geographic area.Captain Selenium (talk) 20:35, 20 August 2009 (UTC)
replies: text: I think the best option is to change this section to it's own article on the list of notable cases so that we can remove any mentions of mining from this article other than the occurrences which would redirect to the main article.Jeffery.D.Sparks (talk) 07:34, 14 April 2013 (UTC)

message: I am curious about the chemical equation for the production of iron sulfate and sulfuric acid from the iron sulfide.  My confusion is that the Iron Sulfide is written as FeS2 which implies the Fe has a +4 oxidation state or that the compound is charged.  I did not think Iron could have any oxidation state besides +2 and +3.Stevemsmith (talk) 17:35, 14 February 2013 (UTC)

This desperately needs clarification, if someone would be so kind.

message: Content Evaluation
The material for this article is broken up and organized into understandable sections, starting with describing what it is and how it occurs, then describing what effects it has before finally explaining how we can treat it. The presentation is understandable. Some of ending sections seem like they were added at the list minute, with 1 or two sources each section. The topic is covered fairly comprehensively. While it covers the effects that acid mine drainage has on the water, the article doesn't really address how it harms the environment. The article is well referenced, with many of them being articles from scientific journals or reports written by agencies. One of the references refers to a Bucknell University news article, another to a New York Times article. The content could be improved with more sources. Many of the paragraphs have only one or two sources. 
Content Quality
This article does have an introduction. While it is understandable, it does not summarize all of the key points. The sections regarding treatment, the metagenomic study and the "microbe and drug discovery" is not referenced to in the introduction. There are several headings, with the larger headings have several subheadings, making it easier to understand how the material is divided. This article contains only images, which are seen mostly in the first half of the article. There are no images in the treatment section or the sections after it. The foot notes are in the appropriate place. The coverage is neutral, with facts being emphasized. Most of the references are reliable, coming from peer-reviewed scientific journals or agency reports. Some of the references are news articles. At471413 (talk) 22:01, 6 November 2017 (UTC)

message: I propose that Uranium Acid Mine Drainage be merged into Acid mine drainage. The content in the Uranium Acid Mine Drainage article could easily be included as a section in the more mature Acid mine drainage article. 2620:117:503F:97:0:0:0:D016 (talk) 20:31, 28 November 2017 (UTC)
replies: text: No, you didn't "fix" it; you put it back. I removed it, as it got no traction whatsoever after 3 months' time (which, quite likely, is because it's a very poor idea. Joefromrandb (talk) 21:29, 31 January 2018 (UTC)
thread_title:  Proposed merge with [[Uranium acid mine drainage]] 

message: Hi. I noticed this line in the article "Negative pH occurs when water evaporates from already acidic pools thereby increasing the concentration of hydrogen ions"
That's not true at all. The reason for negative pH according to "Quantitative Chemical Analysis 9th Ed." by Daniel C. Harris is that the activity coefficient of hydrogen ions increases hugely as the ionic strength of a solution increases. Because acid mine drainage has a very high concentration of sulfate and metal ions the ionic strength is very high. 
I hope this will help you improve this page. Science Is My Life (talk) 15:11, 24 September 2018 (UTC)
