QUALITY PARAMETERS OF TUBE-WELL WATER OF RAMU UPAZILA IN COX’S BAZAR DISTRICT OF BANGLADESH

An investigation was carried out in Ramu during the period of 2013 to assess the magnitude of important quality parameters including pH, As, Fe, EC, DO, Cl^-, SO4^-, NO3^-, HCO3^-, Fe and Turbidity which influence the ground water quality. This is a qualitative study and this study also find out the correlation among As and other important quality parameters. The study revealed that the As concentration was found ranging from nil to <0.01mg/l which is far below the Bangladesh (0.05mg/l) and WHO (0.01mg/l) standard, Mean Fe concentration showed highest value 30.8mg/l in low depth between 20-50ft depth classes. As concentration of the ground water was a negative correlation with depth, Fe, Turbidity, EC, NO₃^-, Cl^- while the correlation was positive for age, HCO₃^-, SO4^-, pH and DO at 5% and 1% level. The study showed that groundwater quality containing these parameters in terms of depth and age is significantly different from the union to union.
