摘要：Inflow groundwater plays a vital role in maintaining an environmental cycle. Water quality assessment is needed for identifying disturbance or contamination of this. In this research, twelve water samples were collected from in and around Maddhapara Granite Mine, Bangladesh during August 2017 to reach in a decision, that is the untreated mine discharged water able to contaminate the groundwater or not. The samples’ heavy metals i.e., Zn, Ni, Fe, Cu, Pb, and Cr were analyzed by Atomic Absorption Spectrophotometer in laboratory, where the average highest value was 123.05 mg/L of Fe. Cr and Cu in those samples were under detection level and Pb concentration was 1.13 to 7.63 mg/L, which surpassed the World Health Organization (WHO, 04) drinking water guideline values of Pb is 0.01mg/L; Ni and Zn were also above the WHO standard. The concentrations of all heavy metals are inversely proportional to the distance of sampling point from the mine. Hence, this study uncovers that the use of granite mine wastewater without any treatment for irrigation purpose has grown the danger of heavy metals contamination in groundwater in future and causing an influential venture for the environment in the longtime term.
