Abstract
- The river Ganges largest tributary is river Yamuna and it's the longest tributary in India serving millions of individuals. In this paper we investigated the ongoing trends in basic water quality guidelines of the River Yamuna which shows huge deviation in Delhi segment. When river Yamuna enters Delhi, it meets the water quality guidelines Class C with respect to Dissolved Oxygen (DO) and Biochemical Oxygen Demand (BOD) but during its exit the water quality deteriorated. After Wazirabad the DO decreases drastically and remains drastic downstream, it was observed most of the time well below the prescribed limit of 4 mg/L and ranges from 0.0 – 10.5 mg/L. The BOD values were also critical usually not meeting the prescribed limit of 3 mg/L and ranges from 1.3 – 61.8 mg/l. The TC values were significantly superior to the prescribed limit of 5000 MPN/100 ml and ranges from 10000 - 920000000 MPN/100 mL. Analysing the values of DO, BOD and TC according to river classification the river Yamuna comes under Class E for the Delhi segment. Due to the influence of industrialization, urbanization, and horticultural advances the Delhi segment gets severely contaminated. The dilution capacity of the river also gets reduced due to significant water abstraction. The chief contributor of contamination in Yamuna River is National Capital Territory (NCT) of Delhi followed by Agra. The DO, BOD in the Delhi segment in river Yamuna represent that regardless of the considerable number of endeavors the water quality isn't fit for assigned best utilizations. The outcomes require inventive points of view in the advancement of a refreshed comprehensive preservation technique for the river Yamuna. [ABSTRACT FROM AUTHOR]
