Abstract: A study was conducted to evaluate the water quality at Matiranga Upazilla under Khagrachari Hill District of Bangladesh. pH values (6.72-7.54) indicated that groundwater was slightly acidic to neutral. Ca (0.4-6.90 mg L-1) Mg (0.55-6.60 mg L-1), Na (4.00-44.00 mg L-1), K (4.75-13.50 mg L-1), HCO3 (0.15-1.20 me L-1 ) and CI (0.30-1.60 me L-1) were predominant along with Zn, Mn and P in lesser amounts. Fe, Cu, As, B and SO4 were found trace to very little amounts. Total dissolved solids (TDS) and sodium adsorption ratio (SAR) values were 35-200 mg L-1 and 0.36-3.40 respectively and indicated that all water were under freshwater’ and excellent’ class respectively. In terms of soluble sodium percentage (SSP), most water was doubtful. SAR (0.36-3.40) and EC (52-300 μS cm-1) values classified the water as CI-SI except one as C2-S1. All water was under the category of soft regarding hardness with ‘suitable’ RSC. Based on As, Fe, Mn, Zn, SO4, NO3 and CI all water was within the safe limit for drinking except 3 samples for Mn and one for As.
