Effects of Disposed-water from Barapukuria Coal Mine, Dinajpur, Bangladesh on Agriculture and Aquaculture

Abstract The environment is a prime concern in the mining industry because of its adverse impact on the solid, liquid, and gaseous surroundings. These three parts of the environment are directly connected to agricultural production. As the Barapukuria coal mine is located in the agricultural zone, its effects can be crucial. Previously, the impacts of the subsidence of the Barapukuria coal mining area were studied. So far, there is no significant study regarding its effects on agriculture. This research has focused on the impacts of the disposed water from the Barapukuria coal mine on the nearer aquaculture and agricultural fields. Therefore, the BOD, COD, DO, TDS, TSS, SS, residual chloride, hardness, alkalinity, carbon, sodium, calcium, magnesium, iron, potassium, sulphate, etc., being present in the disposed-water were analyzed in this study. The values of BOD, COD, DO, pH, TSS, TDS, and TS were lied in the best optimum range to cultivate crops and fisheries. It is also found that the disposed-water of the Barapukuria coal mine is tolerable for agriculture.
