Abstract/ Executive Summary:

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.

Keywords: Maddhapara, Contamination, Drainage Water, Heavy Metals, Granite Mine

Location: Maddhapara, Parbatipur Upazila, Dinajpur, Bangladesh

Start Date: 00-00-2017

End Date: 00-00-2017

Program Area: Crop-Soil-Water Management

Commodity: Water quality

Objectives:

To confirm heavy metal absorption of water completely the Maddapara Granite Mine orientation which has the sexual relationship outside of marriage with the groundwater chemistry.

Methodology:

The location of the study area is far and wide the Maddhapara Granite Mine (MGM) is covering in Maddhapara, Parbatipur Upazila, Dinajpur land, northwestern area of Bangladesh mutually an outlook of roughly 1.44 km². The selection of all sampling points has predetermined the positions, facility, periphery to residential areas and cheek by jowl outdoor area of the granite mine. Twelve mineral deposit samples were taken from twelve antithetical stations from use sump, four surplus water lines, one tide, five concerning plants fields and a well known tube amply by the whole of Geographic Positioning System (GPS) value far and wide the time of August 2017. The mineral deposit samples were united from points by a bucket, far merging directed toward the water. The mineral deposit samples had been well classified by all of sample parity is WS-1 to WS-12. The everywhere study was done by maintaining the following everything but the kitchen sink. The mineral deposit samples, which were stacked from twelve different stations were preserved in a fridge at 4°C for metal analysis. Heavy metal gats a charge out of lead (Pb), zinc (Zn), copper (Cu), nickel (Ni), iron (Fe) and chromium (Cr) experiment was talented by Atomic Absorption Spectrophotometer (AAS) (Model: VarianAA240). Physicochemical properties gat a charge out of pH, electrical conductance (EC), dissolved oxygen (DO), turbidity and total dissolved solids (TDS) are analyzed by via diverse measuring devices. Total Dissolved Solids (TDS) and Electrical Conductivity (EC) were measured by using a portable meter geared by all of the membrane electrodes (Model: HANNA HI 2300). On the other employee, pH and Dissolved Oxygen (DO) were weighted by all of bench-type pH meter (Model: Jenway 3510) and DO meter (Model: HANNA HI 2400) respectively. The chief metal and physicochemical examination of each raw material samples were analyzed in the Laboratory of the Institute of Mining, Mineralogy, and Metallurgy (IMMM), Bangladesh Council of Science and Industrial Research (BCSIR), Joypurhat.

Achievement/Findings:

The appearance of high concentrations of Ni, Zn, Fe and Pb i.e., 100%, 16.67%, 75% and 100% respectively of the analyzed samples beyond the bounds of the WHO, 2004 drinking raw material and irrigation mineral deposit pointers values which cut back be large sufficient shortly not to be eventual community health and environmental care. According to that, the concentrations of Cu and Cr in mineral deposit samples during MGM orientation were under detection level. A little concentration of heavy metals (i.e., Ni, Zn, Fe, Pb) disclosed in WS-12 which was stored from groundwater. But discharged use mineral deposit in irrigation territory and inland climb mineral deposit will be a great case of groundwater contamination. This design expressed that involve sources of arch metals in the water should be closely identified. Improvement of situations and technological (MGM) effluent and contaminated surplus water discharge should be weakened or a water treatment shovel should be placed.
