The present study reports the seasonal and spatial changes in water quality of river Yamuna, India. Surface water samples were collected from three different stretches of river Yamuna . Delhi, Mathura and Agra on seasonal basis from April 2014 to February 2015 and were analyzed for different water quality parameters . water temperature, pH, electrical conductivity, total dissolved solids, total alkalinity, biochemical oxygen demand, chemical oxygen demand, dissolved oxygen, nitrates and phosphates . | 2017 6 5 694-712 International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 6 Number 5 2017 pp. 694-712 Journal homepage http Original Research Article https Seasonal Variations in Water Quality Parameters of River Yamuna India Taskeena Hassan Saltanat Parveen Bilal Nabi Bhat and Uzma Ahmad Limnology Research Laboratory Department of Zoology Aligarh Muslim University Aligarh 202002 India Corresponding author ABSTRACT The river Yamuna is one of the most important and sacred rivers of India. During the past few years the massive pollution has affected its water quality resulting in a foul smelling drain. Seasonal assessment of river water quality would be helpful in evaluating the Keywords temporal variations in river pollutants. The present study reports the seasonal and spatial changes in water quality of river Yamuna India. Surface water samples were collected River Yamuna from three different stretches of river Yamuna . Delhi Mathura and Agra on seasonal India pollution temporal water basis from April 2014 to February 2015 and were analyzed for different water quality quality irrigation parameters . water temperature pH electrical conductivity total dissolved solids total parameters. alkalinity biochemical oxygen demand chemical oxygen demand dissolved oxygen nitrates and phosphates. The mean values of these parameters were used to assess the Article Info suitability of river water by comparing with World Health Organisation WHO and Indian Accepted standards ISI for domestic purpose and University of California Committee of 04 April 2017 Consultants UCC and Bureau of Indian Standards BIS for irrigation purpose. The Available Online sample analysis reveals that river water is not fit for drinking with respect to EC TDS TA 10 May 2017 BOD and COD the concentrations of these parameters exceed the permissible limits of WHO and ISI standards .
