An assessment of seasonal variation in physicochemical parameters of secondary treated wastewater used in Sri Ganganagar and Hanumangarh, Rajasthan

Water is one of the five essential elements of life; Earth (Prithvi), Water (Jal), Fire (Agni), Air (Vayu) and Space (Akash). Quality and quantity of these fundamental elements affects health, ecosystems and economics. Water scarcity and contamination are becoming a big challenge to life support on this blue planet. The present study is aimed to study the seasonal variation in physicochemical parameters like pH, electrical conductivity, COD, BOD, TH, TA and TDS, various cations and anions of secondary treated wastewater of Sri Ganganagar and Hanumangarh, Rajasthan. Various parameters showed distinct seasonal variation with higher value for most of the parameters in pre-monsoon season. Higher BOD values may cause adverse effect on aquatic biota. The study showed a need for regular monitoring of the treatment plants.
