Study of water quality using of Physico-chemical parameters of two perennial ponds of Darbhanga district, Bihar

Abstract

Darbhanga district is known as city of ponds. The present investigation was undertaken the study of the physico-chemical conditions of two perennial ponds- Maharani Pokhar and Raj Pokhar of Darbhanga city. Present study revealed that physico-chemical parameters was comparatively higher of Maharani Pokhar to other pond, Raj Pokhar. The water samples were analyzed for water temperature, transparency, pH, free CO2, chloride, carbonate, bicarbonate, magnesium, dissolved oxygen (DO) and biological oxygen demand (BOD). Higher value of physico-chemical parameters BOD, is considered to be sewage water pollution indicator for eutrophication and it also lower down the fish production.
