Comparative Analysis of Groundwater Quality near a Dumping Ground in Garchuk Area, Guwahati

Abstract

Abstract: This project focuses on analyzing and comparing the water quality of a dumping ground, nearby residential area, and commercial area in Garchuk, Guwahati. Water samples were collected from these three locations using tube wells and various parameters were assessed to evaluate the water quality. The analysis included the measurement of Dissolved Oxygen (DO) and Biochemical Oxygen Demand (BOD). The Winkler method was employed for DO analysis, involving the oxidation of divalent manganese hydroxide precipitate by dissolved oxygen in the water sample. The BOD determination assessed the oxygen required for the biochemical degradation of organic material during a specified incubation period. Results from the DO analysis indicated varying levels of dissolved oxygen in the water samples collected from the dumping ground, residential site, and commercial site. BOD analysis revealed the oxygen utilization and degradation of organic material in the water samples after a 5-day incubation period. Additionally, the concentrations of heavy metals such as lead (Pb), arsenic (Ar), zinc (Zn), copper (Cu), and mercury (Hg) were analyzed in the groundwater samples. The results showed that some heavy metal concentrations were below the detectable limit, while others exhibited measurable levels. The findings of this study provide valuable insights into the water quality of the studied areas, indicating potential pollution levels and the effectiveness of waste treatment processes. These results contribute to better understanding and management of water resources in the Garchuk area, helping to protect the environment and public health.
