Assessment of Parameters of a Running Stream and Still Lake Water

Abstract

Water quality degradation in the River Yamuna persists as a significant impediment to its sustainable
development, despite the enactment of numerous policy initiatives such as Yamuna Action Plan I and
II. This study concentrates on the evaluation of water quality attributes within a 14-kilometre segment
of this river, extending from Sonia Vihar to Kashmere Gate. The primary objective is to scrutinize
water quality conditions both upstream and downstream of Wazirabad Barrage and to compute the
Water Quality Index (WQI) for this river. The utilization of the WQI as a metric is employed to
characterize the pollution levels within the river, subsequently facilitating an assessment of the
overall sustainability of the Yamuna River based on these pertinent water quality parameters.
Furthermore, the paper conducts a comprehensive analysis of water quality parameters in Bhalaswa
Lake located in Delhi. This analysis aims to determine the feasibility of transforming the lake into a
water sports complex and ascertain its suitability for recreational activities like boating and
swimming. The study's findings reveal that the lake's water is heavily contaminated, rendering it
unsuitable for recreational use. The water exhibits a high concentration of organic matter, a slightly
elevated pH level, and an excessive Biological Oxygen Demand in comparison with the established
benchmarks established by the Central Pollution Control Board for outdoor bathing. In conclusion,
the paper delves into a discussion of the water quality issues affecting Bhalaswa Lake.
