Groundwater is an important water resource for drinking and irrigation purposes in Ughelli, Delta State. The groundwater sources are used with little attention to their quality status in addition to increased threat of anthropogenic contamination in view of rapid growth in population and oil exploitation activities. The objectives of this study were to determine the physico-chemical characteristics and heavy metals content of groundwater, its hydrogeochemical controls and suitability for drinking and irrigation. Twelve groundwater samples were collected from the Ughelli. Field measurements of physical parameters were preceded by chemical analyses of the samples for major ions concentrations and bacteriological content. The groundwater has pH ranging from 3.57 to 6.43 implying that the groundwater sources are acidic. Electrical conductivity (<25 μS/cm) and total dissolved solids (<31 mg/l) were low for all most of the water sources, suggesting low-mineralized freshwater. The order of abundance in anionic and cationic content is of the order; K > Mg > Ca > Na > Zn > Fe >NH3 > Mn > NH4 > Cu > Al > Pb > Cd and F > PO4 > SO4 > NO3 > Cl > NO2 > Cr. Besides pH, EC, TSS, Mn, Mg, Ca, NO2, NH3, NH4, Cu, BOD, P and Fe (in some or all locations), all other measured parameters fall within WHO guidelines for drinking and domestic purposes. Irrigation quality indices (Electrical Conductivity (EC), Total Dissolved Solids (TDS), Sodium Adsorption Ratio (SAR), Magnesium Adsorption Ratio (MAR), Kelly’s Ratio (KR) and Soluble Sodium Percentage (SSP)) revealed that the analyzed groundwater were poorly to fairly suitable for irrigation.
