ABSTRACT
Water is essential for open-pit mining’s dust-suppression systems and coal processing units. To meet this requirement, mining companies must buy surface or groundwater supplies from neighbouring domestic or agricultural users. After mining, these water resources are rarely replenished, permanently reducing agricultural production. Whether water is acidic, neutral, or basic depends in large part on the quality of the water. Gunjan Ecological Park Pit Lake’s pH value is 7.09 at its lowest, and Joyalvanga 1 Pit Lake has a pH value of 7.88 at its highest. Chora had the lowest level of hardness (180.42 mg/l), while Dalurbandh pit lake had the highest level (334.75mg/l). The lowest DO (Dissolved Oxygen) level was found in Chora pit lake at 3.90 mg/L and the highest DO level was 6.32 mg/ l. Considering the water quality of pitlakes ,it is reflected that water of pitlakes has high mineral and nutrient ccontent which can be used in various aquaculture practices as well as in irrigation for their sustainable use.
