An assessment of water quality of river Yamuna at water works station, Agra
The present study is an effort to know the water quality of river Yamuna. The water of river Yamuna is collected and treated before supplying to the city. As the Yamuna river comes to Agra passing through several cities, some of them are industrial which dump their waste into the river. Besides this city waste or sewage is also dumped. As the river Yamuna passes through Ghats due to which various organic, as well as inorganic waste, are also added into the Yamuna river which increases the pollution load. “During our study at Water Works, Agra, It was observed that the pH, Hardness, Chloride, and Alkalinity are always higher than the IS Standards. In river Yamuna’s water due to dumping problem many problems arise which increases the colour, pH as well as other physio-chemical parameters. Due to which the colour becomes higher than the normal standard as by IS standards (Which is maximum 20 Hazon)”. Due to such an increased pollution in Yamuna river water, the water treatment at Water Works, Agra become difficult and the chlorine dosing (Which is used for disinfection) and Alum dosing (For sedimentation) becomes higher and dosing quantity changes according to the seasonal variation in Yamuna river water.
