ABSTRACT
Related water quality tests were carried out in different areas of Chittagong district. Water qualities of eight upazila/thana were examined and found significant variation among them. Water quality parameters did not cross the safe limit of drinking water standard largely. For example TDS (highest value-711mg/l; standard limit-1000mg/l), Alkalinity (highest value-254mg/l; standard limit-500mg/l), Sulfate (highest value-18mg/l; standard limit-400mg/l), Phosphate(highest value-3.32mg/l; standard limit-6mg/l), Total Hardness(highest value-68mg/l; standard limit-200-500mg/l), Cu(highest value-0.19mg/l; standard limit-1mg/l), Zn(highest value-0.06mg/l; standard limit-5mg/l) and Nitrite (highest value-0.05mg/l; standard limit-1mg/l) value of any areas did not cross the safe limit. Some areas crossed the standard level in case of pH and Free Chlorine; however the value did not correspond with much deterioration. A relative comparison with the safe limit, As and Fe of some areas were identified at risk. Mirsharai got the As concentration 0.45 mg/l. Variability in Fe was found in six upazila such as Panchlaish(3.05 mg/l), Kotowali(2.22 mg/l), Chandgaon(2.39 mg/l), Shatkania(1.69 mg/l), Banskhali(3.12 mg/l) and Fatikchari(2.82 mg/l) of Chittagong over the standard level.
Key words: Drinking water, water quality, shallow tube-well and Chittagong
