Comparative studies on seasonal fluctuation in physico-chemical properties of water on biotic community of two sewage-fed fish ponds of Madhubani

Abstract

Water intended for human consumption should be “safe” and “wholesome” i.e. free from pathogenic agent and harmful chemicals, pleasant to taste and usable for domestic purpose. The study area selected was Gangasagar pond and Raj Pond of Madhubani, Bihar. The physico-chemical parameters like temperature, pH, DO, total hardness, total alkalinity and turbidity were studied to analyse the water quality of the ponds. Water supports life on earth and around which the entire fabric of life is woven. The requirement of water in all lives, from micro-organism to man, is a serious problem today because all water resources have been reached to a point of crisis due to unplanned urbanization and industrialization (Singh et al., 2002). Generally speaking, water pollution is a state of deviation from pure condition, whereby its normal functioning and properties are affected. Aggravated environmental problems often reflect the misuse or misunderstanding of technology. The pollution of this ponds are a matter of great concern, since it has reached an alarming level due to inflow of large volume sewage and solid wastes.
