Analysis of Pollution Sources and Control Measures for the Karatoa River: A Comprehensive Study on Water Quality and Remediation Strategies

This paper examines the properties of pollution sources in the Karatoa River and possible measures to control it. In today’s world, more than 70% of the freshwater in liquid form in Bangladesh is unfit for consumption. This problem is not unique to Bangladesh, as other countries are also facing similar issues. The paper provides a clear explanation of this problem with the help of a considerable number of references. It studies various sources of pollution such as sewage discharge, industrial effluents, and agricultural runoff, and their potential impact. The Karatoa River is severely polluted from different wastewater sources, which are properly investigated here, and remedial measures are described with graphical representation. It explains various prescribed standards for different categories of inland water. It identifies the potential and extent of various components that pollute the water. Finally, the paper shows the effects of water pollution in a nutshell. The remedial measures suggested include pollutant traps, water treatment plants, gross pollutant traps, bio-retention basins, and effluent treatment.
