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.
Although the term "trophic index" is commonly applied to lakes, any surface water body may be indexed. The TSI of a water body is rated on a scale from zero to one hundred. [1] Under the TSI scale, water bodies may be defined as: [1] oligotrophic (TSI 0–40, having the least amount of biological productivity, "good" water quality);
Water drawn directly from a stream, lake, or aquifer and that has no treatment will be of uncertain quality in terms of potability. [ 3 ] The burden of polluted drinking water disproportionally effects under-represented and vulnerable populations. [ 11 ]
The map shows the locations of the lakes with a volume over 4 x 10 6 m³ and gives an indication of the volume of water in each lake. The markers suggest this by showing the size of a drop of water where the volume of the drop would be in proportion to the quantity of water in the lake (the diameter of the drop is proportional to the cube root of the lake's volume).
A biotic index is a scale for showing the quality of an environment by indicating the types and abundances of organisms present in a representative sample of the environment. It is often used to assess the quality of water in marine and freshwater ecosystems.
Drinking water quality standards describes the quality parameters set for drinking water. Water may contain many harmful constituents, yet there are no universally recognized and accepted international standards for drinking water. Even where standards do exist, the permitted concentration of individual constituents may vary by as much as ten ...
Manasbal Lake is a freshwater lake located in Safapora area of Ganderbal District in Jammu and Kashmir, India. The name Manasbal is said to be a derivative of Manasarovar . [ 2 ] The lake is encircled by four villages viz., Jarokbal, Kondabal, Nesbal (situated on the north-eastern side of the lake) and Gratbal. [ 3 ]
