I've noticed that quite a few of the links are out of date or no longer exist. Could someone fix this? —Preceding unsigned comment added by Flan318 ( talk • contribs) 18:51, August 26, 2007 (UTC)

Acid Rock Drainage seems like a more generalized term, but Acid Mine Drainage gets more google hits. Opinions? SReynhout 22:41, 7 January 2006 (UTC)
I disagree with your last comment, I regularly see ARD used in North America with regards to effluents which do not originate at mines. My opinion on this is that the article should be titled Acid Rock Drainage with a disambiguation sentence in the opening, While having Acid Mine Drainage redirect to the ARD article. — Preceding unsigned comment added by 137.122.30.165 ( talk) 22:20, 5 November 2012 (UTC)
I can't comment on the use outside of science but I am fairly certain that we should switch to acid rock drainage. To put the debate to rest we could contact someone from the international conference for acid rock drainage to see why they chose that name, or simply agree that mining is the primary cause of ARD but mining is not part of ARD. Not to mention I think that using the term acid mine drainage has a bit of a negative light on mining and based on that alone it should be changed to a more neutral term. Yes we all know mining causes ARD and that's important to mention, but it is more important to talk about how it's formed, what it's effects are, etc. If we focus on those topics then I don't think any of the mentioned mining aspects are that important to the topic anyways. The only section that seems to be specific about mining is the "list of selected acid mine drainage sites worldwide" which we can see from other comments is too long and could be much much longer. The best course of action would be to remove the mentions of mining from this article and create a subsection on mining induced ARD and change the list of notable cases to it's own page as well. We would use the current article for the science of ARD and focus on the chemistry and treatment. Jeffery.D.Sparks ( talk) 07:46, 14 April 2013 (UTC)
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)
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)stevemsmith
Linked "yellow boy" of 1st image caption to section describing.
Was about to post the following here until I found wherewithall to scroll down:
This desperately needs clarification, if someone would be so kind.
Found nothing at either of these regarding this context:

Hello fellow Wikipedians,
I have just added archive links to 8 external links on
Acid mine drainage. Please take a moment to review
my edit. If necessary, add {{
cbignore}}
after the link to keep me from modifying it. Alternatively, you can add {{
nobots|deny=InternetArchiveBot}}
to keep me off the page altogether. I made the following changes:
When you have finished reviewing my changes, please set the checked parameter below to true to let others know.
An editor has reviewed this edit and fixed any errors that were found.

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)
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)

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.
