ASSESSMENT OF WATER AND SOIL QUALITY PARAMETERS IN CANALS OF DHAKA NORTH CITY CORPORATION (DNCC) AREA AND ITS IMPACT ON THE ENVIRONMENT

Abstract

Understanding environmental health and directing sustainable management methods depend on evaluating water and soil quality criteria in urban canals. This study aims to assess the environmental impact of the water and soil quality parameters in the canals of the Dhaka North City Corporation (DNCC) area. The present condition of the water and soil quality in the study region was evaluated through an extensive examination of physical, chemical, and biological parameters. The study's findings demonstrated notable fluctuations in soil properties like pH, organic matter content, and nutrient levels, as well as in water quality parameters like turbidity, total suspended solids (TSS), total dissolved solids (TDS), fecal coliform (FC), and chloride concentrations. The results show how human activities affect the water and soil quality in the DNCC area. These activities include urban runoff, industrial discharges, agricultural practices, wastewater discharges, and sewage discharges. The report also emphasizes the possible adverse effects of high pollution levels on the environment, such as threats to human health, aquatic ecosystems, and the sustainability of the environment. Recommendations are made based on the assessment results to address issues with water and soil quality in the canals of the DNCC area. These recommendations would improve pollution control measures, encourage sustainable land use practices, modernize wastewater and sewerage treatment facilities, and encourage community engagement. Considering all criteria, this study offers insightful information about the environmental dynamics of urban canals. It lays the groundwork for well-informed management interventions and decision-making aimed at enhancing the soil and water quality of the urban canals and advancing sustainable urban development in DNCC.
