Talk:Freshwater environmental quality parameters

Dissolved oxygen anomaly
A perennial spring originating from Mount Shasta snow melt emerges from a lava tube into a pond 20 km from the summit under pressure causing a kinetic energy-induced surface elevation increase (or boil). Dissolved oxygen sensors inserted into the throat of the spring reveal diurnal variation. Although the trend is what might be expected of photosynthesis, the reaction rate appears unrealistically rapid for an unmixed source uncolonized by algae. Soluble concentrations of arsenic and antimony suggest the possibility of oxygen release from photo-catalyzed decomposition of unstable oxo-anions. Can anyone offer a reference supporting that hypothesis?Thewellman (talk) 19:09, 4 August 2011 (UTC)

The lead section includes a good introduction and mentions the topic clearly, summarizing the article's topic. The article has general information for content, and the content is relevant to the topic. I also think the article's overall tone is neutral, but in the sampling part, it would be better if there was additional information about the reason for the difficulty of freshwater sampling with the citation from reliable sources. The article has several references to support it, but I believe that the number of the sources is small and needs additional sources to support it. Nevertheless, most current sources are peer-reviewed publications, and just more reliable sources are needed to have strong support. Furthermore, the organization and writing quality are delicate and easy to read.Heeyeons (talk) 03:56, 18 April 2022 (UTC)
