Turbidity and cancer[edit]

Is there a reference to the statement: "High water turbidity is the leading cause of gastrointestinal cancer in the United States". I could imagine that turbidity caused by organic compounds together with chlorination creates chlorinated organic molecules which will kill u and u will die. This could be very carcinogenic. This would be an argument against chlorine for water treatment. I never heard that turbidity itself was cancerogenic. 212.183.60.114 22:00, 28 February 2007 (UTC)http://www.aee-intec.at[reply]

The piece I wrote on turbidity in water quality is modified from a similar piece I wrote for my company at [1] and provided to the Wikipedia with appropriate permission Marshman 17:31, 5 Aug 2003 (UTC)

Should we not split this up, and have separate articles for the secchi disk and nephelometer? Tonderai 21:32, 28 Nov 2003 (UTC)

There already are separate artticles about those subjects. What would you split up? - Marshman 02:30, 29 Nov 2003 (UTC)

Sorry ;) I didn't check this out properly before I posted. I'll do that next time. Great stuff, btw. Tonderai 16:54, 29 Nov 2003 (UTC)

I didn't either until after I first responded to you. Anyway, you may want to move the bit about compensation depth and the Secchi Disk over to Secchi disk where it would be more pertyinent instead of under Turbidity where the connection is more tenuous - Marshman 17:06, 29 Nov 2003 (UTC)

Hey, is turbidity related to conductivity in any way? I'm working with something aquarium-related at the moment, and they seem to be, but I have nothing. Maybe it's a different kind of conductivity? Anyway, if someone else wants to look into that, I'd appreciate it. Speaking of which, how is turbidity related to aquariums anyway? Brazenbell

There is no direct corelation. Sodium Chloride (Salt) disolved in water produces very little or no change in turbidity but makes a huge difference on conductivity.

I would imagine the turbidty acts as receptors for the pollutants that contribute to cancer; in other words the carcinogen hitches a ride on the turbidity causing particle in the drinking water into the body. The less turbid the water is, the less places for pollutants (such as dioxin's) to travel with the water.

THere is no way that phytoplankton, a one celled organism, can cause gastrointestinal disease. There is just no way. I think someone should edit this. 67.98.32.210 11:57, 9 April 2007 (UTC)Chris Singletary : Analyzer Specialist III[reply]

I created a new section heading on Causes and Effects. The phytoplankton sentence is now in the "Causes" paragraph, while the GI disease sentence is in the "Effects" para. No references for these sentences yet. (I did not write the sentences.) The link between the two phenomena is not direct. It is related to pathogens attaching to the suspended solids, which may consist of various gunk (how's that for a scientific term?) attaching to the plankton. Perhaps someone more knowledgable that I can provide a better explanation of the connection. Moreau1 (talk) 07:15, 24 February 2008 (UTC)[reply]

"Turbidity is generally caused by phytoplankton"[edit]

i doubt that... it would mostly be caused by clay in rives wouldn't it? --Hypo Mix 09:40, 5 June 2007 (UTC)[reply]

It is indeed caused by sedimentation, human-caused and otherwise. This would be clay in some geographic areas, maybe other soil types elsewhere. I added a paragraph in the new Causes and Effects section on sedimentation and stormwater pollution. Moreau1 (talk) 07:15, 24 February 2008 (UTC)[reply]

There's a mistake, I think[edit]

  In the first paragraph it says viruses, bacteria, and bacteria... is something wrong is it just me?

Why isn't there anything about the effects of turbidity on organisms and SAV's?[edit]

Turbidity blocks out a lot of sunlight reaching streams or lakes, damaging the various organisms living there, and that is perhaps the chief problem with it. Why isn't there a section that talks about this? 71.163.26.70 17:42, 11 November 2007 (UTC)Anon[reply]

I added a sentence on SAV effects, such as that seen in the Chesapeake Bay, in the Causes and Effects section. Moreau1 (talk) 07:15, 24 February 2008 (UTC)[reply]

Nice article[edit]

Just taking a moment to thank all those involved in this article; it gives a nice overview, clearly explains the basic concepts and introduces a lot of terms and ideas that may be encountered elsewhere, explaining roughly what they mean. This is exactly what I always thought Wikipedia was for. Naturally all articles can be improved, but this article was exactly what I needed to get me started on something. Thanks guys. 86.141.90.75 (talk) 11:28, 2 June 2008 (UTC)[reply]

spelling error[edit]

Second paragraph "....if a liquid sample is left to stand (the settable solids), very small particles..."

settable - should this be settleable? (Looks like a word processor has corrected settleable to settable) 115.186.196.19 (talk) 02:10, 14 July 2011 (UTC)[reply]

Definition[edit]

Most definitions for "turbidity" refer only to suspended solids, and not to dissolved solids. This contradicts the description given in the opening paragraph of the article. Any dissolved substance is "in solution" and therefore not visible as turbidity. Landroo (talk) 14:45, 25 June 2014 (UTC)[reply]
