A study was conducted to evaluate the groundwater quality at Phulpur thana of Mymensingh district in Bangladesh. Water samples from 14 deep tubewells were analyzed for pH, EC, TDS, Na+, K+, Ca++, Mg++, Fe, P, B, NO3-N, SO4=, Cl-, CO3= and HCO3. In addition SAR, SSP and RSC were calculated following standard equations. The range of EC was 180-380 � Scm-1 and SAR 0.22-0.80 and these two parameters indicated that three samples were in low salinity-low alkali` and 11 were in medium salinity-low alkali` hazard class. There was no chloride toxicity in the area. The presence of SO4=, NO3- and P were negligible. As regards boron and SSP, all waters were of good` to excellent` class. In respect of TDS all were fresh water`. On the basis of RSC values all samples were of suitable` class. As a whole, groundwater of the area can safely be used for long-term irrigation. But some of those may not be suitable for drinking and industrial uses in consideration of Fe concentration, TDS and pH values. Among the quality determining factors SSP and SAR were highly correlated where correlation coefficient was 0.97. <br>
