Salvia yangii, previously known as Perovskia atriplicifolia (/ p ə ˈ r ɒ v s k i ə æ t r ɪ p l ɪ s ɪ ˈ f oʊ l i ə /), and commonly called Russian sage, [2] is a flowering herbaceous perennial plant and subshrub. Although not previously a member of Salvia, the genus widely known as sage, since 2017 it has been included within them.
Freshwater environmental quality parameters are those chemical, physical and biological parameters that can be used to characterise a freshwater body. Because almost all water bodies are dynamic in their composition, the relevant quality parameters are typically expressed as a range of expected concentrations.
Salvia subgenus Perovskia is a group of species within the flowering plant genus Salvia, which prior 2017 were treated as the separate genus Perovskia. [2] Members of the group are native to southwestern and central Asia.
The National Water Quality Inventory Report to Congress is a general report on water quality, providing overall information about the number of miles of streams and rivers and their aggregate condition. [65] The CWA requires states to adopt standards for each of the possible designated uses that they assign to their waters.

Wastewater quality indicators are laboratory test methodologies to assess suitability of wastewater for disposal, treatment or reuse. The main parameters in sewage that are measured to assess the sewage strength or quality as well as treatment options include: solids, indicators of organic matter, nitrogen, phosphorus, indicators of fecal ...
Water quality modeling helps people understand the eminence of water quality issues and models provide evidence for policy makers to make decisions in order to properly mitigate water. [1] Water quality modeling also helps determine correlations to constituent sources and water quality along with identifying information gaps. [2] Due to the ...
Bacteriological water analysis is a method of analysing water to estimate the numbers of bacteria present and, if needed, to find out what sort of bacteria they are. It represents one aspect of water quality. It is a microbiological analytical procedure which uses samples of water and from these samples determines the concentration of bacteria ...
