Abstract: This study examined the chemical quality and suitability of 27 water samples of Narayanganj municipal area in Bangladesh for drinking purposes. The pH, electrical conductivity (EC), total dissolved solid (TDS), Na, K, Ca, Mg, Fe, Mn, Zn, Cu, NO3-N, SO4-S, CO3, HCO3, Cl and total hardness (HT) were analyzed. pH of waters were just neutral to alkaline in nature. EC and TDS values varied from 165 to 1770 μS cm‾1 and 100 to 1020 mg L‾1, respectively. Appreciable amount of Ca and Mg were present resulting higher water hardness. The Na concentration was as high as 5.98 to 389.99 mg L‾1. Cl was dominant among the ionic constituents. Fe, Mn, Zn, Cu, NO3-N and SO4-S concentrations were within the safety limit. Significant amounts of Cl were detected in drinking waters exceeding the level of U.S. Environmental Protection Agency (USEPA). The result of present findings indicated that groundwater contained some chemical parameters that exceeded the upper limit of standard. WASA water was found suitable in all respect while some groundwater samples were unsuitable for drinking and domestic purposes.
