Assessment of water quality using physicochemical parameters of Ranchi Lake (Bada talab)

Akshay Kumar Verma & Ashok Kumar Nag

ABSTRACT:

Water is an integral part of life; it is a necessary element on Earth. Up to two-thirds of the human body is made of water. The current study focuses on the seasonal changes i.e. winter (November 2021-February 2022), summer season (March 2022-June 2022) and rainy season (July 2022-October 2022) over a single year in the physicochemical parameters of Ranchi Lake also known as Bada Talab. Standard procedures were used in the study to assess a number of physico-chemical characteristics. Five different sites were taken for sampling of water bodies i.e. S1 (in front of Seva Sadan), S2 (in front of Himanshu Hiramani Eddapa house), S3 (in front of Modern English School), S4 (in front of Siyaram Narsingh Mandir), and S5 (near Vivekananda Statue). The maximum level of Dissolved Oxygen (DO) was identified at site 5 (near Vivekananda Statue), which is a less polluted zone, following a year-long series of assessments conducted in all seasons, including winter, summer, and rainy. In compared to all other locations, site 1 (in front of Seva Sadan) had the greatest levels of Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Dissolved Solids (TDS), conductivity, total hardness, and total alkalinity. Household and hospital waste is more harmful to this location, and it was discovered to be highly polluted.
