Good question.........it depend on the sampling from river. Water quality of river determined the suitability of water Please more detailed from RS

Yohan Mahagamage

Dear Nath,

Mass bathing highly uses soaps which content water-soluble sodium or potassium salts of fatty acids. Therefore, its change the ions composition in water such as sodium, potassium and other related elements. Further, Soaps are made from fats and oils with a strong alkali and increase pH in the water. Sometimes turbidity and organic matter may increase due to interrupt of sediment in the bottom. Therefore, TDS, TSS, TS and turbidity may increase time to time.

Microbial pollution also can be seen in these mass bathing places, Therefore, total coliform and feacal coliform bacteria and some pathogenic bacteria such as Salmonella spp. and Shigella spp. can be recorded.

Interesting

I am agree with Mahagamage Sir
