Talk:Wastewater quality indicators

Effect of oxygen level
"...are essentially laboratory test measures of the amount of oxygen in a wastewater. The amount of oxygen in a wastewater is in turn a measure of whether or not that wastewater will have a significant adverse effect upon fish or upon aquatic plant life."

Incorrect. It is the oxygen depletion, not the oxygen itself.

Actually I don't think that this article should exist. These arent the only quality indicators and BOD COD are covered elsewhere. —Preceding unsigned comment added by 24.147.201.53 (talk • contribs) June 10, 2006 (UTC)


 * If the oxygen level in a wastewater is very low, then it has been depleted of oxygen and will have an adverse effect on fish and aquatic life. If the oxygen level is fairly normal, then it has not been unduly depleted of oxygen and will not have an adverse effect.  So the quoted statement is not incorrect.  We have only a semantic difference.  Perhaps it could be re-stated differently. Also note that the BOD and COD do not really measure oxygen level, they measure oxygen demand.  A low BOD means a wastewater that will not have a significant adverse effect and a high BOD means that it will have a significant adverse effect. In short, that is what I meant when I used the words "essentially laboratory test measures".


 * I will re-word it to read "... are essentially laboratory tests to determine whether or not that wastewater will have a significant adverse effect ...". - mbeychok 17:49, 11 June 2006 (UTC)


 * I disagree that BOD and COD are covered from the same viewpoint and to the same extent elsewhere. - mbeychok 03:35, 11 June 2006 (UTC)

Further review
on further review, I note that this entire article is within the article: wastewater. (with modifications) —Preceding unsigned comment added by 24.147.201.53 (talk • contribs) June 11, 2006 (UTC)


 * Yes,it has been used as a section in the article wastewater. By the way, you really should click on the + tab at the top of the Discussion page to enter a new comment subject as well as the comment itself. And it is considered good form to also sign your comments by using tildes, like this ~ ... which will automatically add your user name or IP and the date. - mbeychok 17:50, 11 June 2006 (UTC)

Expansion request
Some more material needs to be added to cover other tests mentioned in water quality, or this article should be renamed to "water oxygen demand" or somesuch. -- Beland 17:04, 9 August 2006 (UTC)

Suggested move
I suggest this article should be moved to Water quality indicators whether or not the water is waste the indicators are still valid. It should include elements in Category:Water quality indicators--Alex 15:16, 30 October 2006 (UTC)


 * Alex, I assume that by "move to Water quality indicators", you really mean "re-name the article to Water quality indicators". If so, I see no reason why that would not be acceptable. - mbeychok 23:30, 30 October 2006 (UTC)
