Assessment of water quality parameters of Bhalswa Lake in New Delhi

Bhalswa Lake in New Delhi is one of the important lakes which are being severely degraded because of the effluent/sewage coming from nearby dairy and residential area. In this study, some physiochemical characteristics of Bhalswa Lake were investigated. Physical parameters such as electrical conductivity (EC), salinity, total suspended solid (TSS), total dissolved solids (TDS) and chemical parameters such as pH, alkalinity, hardness, chloride, sulphate, nitrate, phosphate, dissolved oxygen (DO), chemical oxygen demand (COD), biochemical oxygen demand (BOD), sodium, potassium and calcium were examined. Results of the study indicated that lake water is highly contaminated and not suitable for recreational activities as it contains high amount of organic matter, high algal growth, slightly high pH, BOD is high as compare to given standards by CPCB for outdoor bathing. The study discusses the water quality of Bhalswa Lake and comprises the water quality with given standards. © 2017 Inderscience Enterprises Ltd.
