Abstract: | Comparative study was conducted to correlate Arsenic (As), Iron (Fe), Copper (Cu), Manganese (Mn), Calcium (Ca2+), Magnesium (Mg2+), Potassium (K+), Nitrate (NO3¯), Phosphate (PO43¯), and Ammonia (NH3) by determining their concentration at different depth of the tube-wells in the selected study area at Singair, Manikganj Bangladesh. Total 99 tube-well water samples were collected from the study area. In most of the sampling points the present concentrations of As were less than the previous concentrations. The correlation between As and Fe was positively significant. It can be suggested possible adsorption/coprecipication of As with Fe in shallow aquifer. However, the relationship between As and Mn was not significantly observed. On the other hand, relationship between Cu and As showed a positive significant correlation. The correlation between As and PO43¯ was also significant, although the correlation between As and NO3¯ was not significant. PO43¯ may be comes from phosphate fertilizers application and can be a contributer of As in the shallow aquifer. The PCA biplot also indicated the significant relationship between As, Cu, Fe and PO43-. Excessive withdrawal of tubewell water along with aquifer dynamics along with ionic interference might be responsible for the mobilization of As in the study area. |
