Eutrophication was one of the Natural sciences good articles, but it has been removed from the list. There are suggestions below for improving the article to meet the good article criteria. Once these issues have been addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake. | ||||||||||||||||

This article was the subject of a Wiki Education Foundation-supported course assignment, between 17 January 2022 and 1 May 2022. Further details are available on the course page. Student editor(s): Kurt Krautmann ( article contribs). Peer reviewers: Winde068, Aderush, Metikatic, Cruzb005.
I am proposing to merge the article on nutrient pollution to here as well. An alternative option would be to move only the general bits and leave the rest behind, then renaming the article to nutrient pollution in the United States. Comments anyone? EMsmile ( talk) 13:07, 15 June 2021 (UTC)
Let's make it a bit more specific. This is the current table of content of nutrient pollution. I've indicated which sections overlap nearly 100% with the same content at eutrophication:
1Nutrients --> similar content at eutrophication 1.1Nitrogen 1.2Phosphorus 2Environmental impacts --> similar content at eutrophication, except for the part about nitrates in drinking water, fish kills from high ammonia 3Sources of high nutrient runoff --> very similar content at eutrophication 3.1Point sources 3.2Nonpoint sources 3.3Other sources 4Mitigation of nutrient pollutant discharges --> very similar content at eutrophication 4.1Nutrient remediation 4.2Nutrient trading 4.3Nutrient source apportionment 5Country examples 5.1United States
So how could we restructure this so that it doesn't overlap to 90% with eutrophication? That link above that User:Moreau1 posted is useful: https://www.epa.gov/nutrientpollution/effects We could perhaps restructure along those lines provided that any content that is the same for eutrophication is not duplicated but linked (perhaps excerpts could be used as well). In that sense, the eutrophication article could contain the bulk of the content, and then only the things that are in addition to that should be detailed in the nutrient pollution article. EMsmile ( talk) 08:37, 10 February 2022 (UTC)
There are lots of pairs of distinct topics that have some overlap. Overlap is not a reason to merge them. North8000 ( talk) 14:19, 21 February 2022 (UTC)
At least those contents should be focused in one particular place and the other two articles should just refer across for that content. It would help to decide on which article should have the overview content and which has the detailed content in each case. EMsmile ( talk) 10:08, 22 February 2022 (UTC)
Being a limnologist I would agree with Velella that eutrophic is just one of the trophic states of water bodies and that much of the discussion about eutrophication is related to hypertrophic systems where cyanobacteria (blue-green algae) blooms occur. We did make improvements by closing the article on cultural eutrophication and moving it into its own section in this article. Because eutrophication is a relatively common technical term it is therefore of importance in this article that people understand that it encompasses the process of shifting from oligotrophic to mesotrophic to eutrophic to hypertrophic states. The shift beyond this to dystrophic systems can also be mentioned (the latter being the final stage before a lake becomes an acid bog dominated by Sphagnum - the precursor to peat). The article on dystrophic lakes is a good one ( /info/en/?search=Dystrophic_lake). I think the lead of the article explains most of this and as pointed out by EMsmile the good article on the different trophic states needs to be better cited here. ASRASR ( talk) 13:49, 25 February 2022 (UTC)
I have the pleasure of making some important improvements to this article especially re marine aspects thanks to input from Professor Tim Jickells (Univ of East Anglia). These changes are being made Feb 8, 2022. ASRASR ( talk) 17:08, 8 February 2022 (UTC)
Suggest that the following section be removed since it is repetitive /info/en/?search=Eutrophication#Overall_ecological_effects ASRASR ( talk) 20:08, 8 February 2022 (UTC)
There was a hidden comment which said "An alternative definition: Eutrophication as defined by Nixon, 1995 is the increase in organic matter to an ecosystem. Most commonly, eutrophication is the process in which a body of water becomes overly enriched with minerals and nutrients inducing excessive growth of algae, often resulting in oxygen depletion as bacteria respire this excess organic matter." I don't know what this Nixon 1995 reference is and whether it's important? Should we add a section on terminology maybe? EMsmile ( talk) 14:17, 22 February 2022 (UTC)
There was a hidden comment about Nomura's jellyfish, do we really need it? If so, we'd need a reference to go with it: "Other species (such as Nomura's jellyfish in Japanese waters) may experience an increase in population that negatively affects other species." EMsmile ( talk) 14:19, 22 February 2022 (UTC)
In the article we have a section on "terrestrial ecosystems" but in the first sentence of the article we define eutrophication as referring to water bodies. How can this be resolved? I am wondering if we should add a section on terminology to explain this. The term "terrestrial eutrophication" is not widely used, a Google search brings up only 27,000 hits.

A student ( User:Kurt Krautmann) recently added a lot of content about Aluminum Sulfate Treatment. While the text seems to be OK and with suitable references, I would argue it is too detailed for this kind of overview article that eutrophication is and therefore not in line with WP:DUE. It needs to be condensed or moved to a suitable sub-article (perhaps to algal bloom? or to nutrient pollution?). Also I wonder if this kind of treatment is actually widely used. The references seem pretty old. If it was state of the art then surely there would be more recent references available? Pinging ASRASR and User:ASRASR EMsmile ( talk) 10:26, 9 May 2022 (UTC)
It is an expensive short-term solution to clear lake or pond water of phosphate and deposit it to the benthic zone. It can have serious side effects like acidification and toxic effects on organisms (fish and invertebrates).? I see the existing text quoted a Swedish publication from Uppsala University which makes it sound like it's widespread and without problems:
In a large scale study, 114 lakes were monitored for the effectiveness of alum at phosphorus reduction. Across all lakes, alum effectively reduced the phosphorus for 11 years. While there was variety in the longevity, (21 years in deep lakes and 5.7 years in shallow lakes), the results express the effectiveness of alum at controlling phosphorus within lakes. [2].
