Study on Different Sources of Wastewater in the Korotoa River: Focus on Medical Wastewater

Abstract

Sheikh Hayath Mahmud*

Wastewater originating from various sources has been gradually polluting the Korotoa river. Notably, medical wastewater contains hazardous chemicals, including harmful substances that may be used in treatment. In this study, it identifies the composition of waste present in medical wastewater, which is indiscriminately disposed of into the Korotoa river. Unfortunately, people who bathe or fish in the Korotoa river face serious health risks due to exposure to this contaminated water. Skin diseases are prevalent among those who come into contact with it. Additionally, several hospitals situated near the Korotoa river discharge chemical-laden wastewater directly into the river on a daily basis. To address this issue, it assesses the water quality of the Korotoa river and compare it against the standard values provided by the Bangladesh Environment Conservation Rules (BECR 1997). Different parameters such as PH, BOD, COD, DO, Turbidity, color, TS, TSS, TDS and Alkalinity are tested for the water sample collected from different hospitals effluent. All parameters exceed the standard value which is very much alarming. Furthermore, it proposes potential measures to mitigate pollution in the Korotoa river, which are detailed in this paper.
