Abstract: Twenty-One (21) water samples collected from seven (7) wells and fourteen (14) boreholes groundwater sources in the Delta Central region of Delta State of Nigeria were analyzed for hydrochemical constituents, to assess their quality. Physiochemical Parameters investigated include PH, temperature, total dissolved solids (TDS), electrical conductivity (EC), turbidity, and total suspended solid (TSS). Anions such as CL–, SO42-, NO3–, PO42- and cations such as Ca2+, and Mg2+ were determined, employing Atomic Absorption Spectrometer (AAS). Dissolve Oxygen (DO) biochemical oxygen demand (BOD), chemical Oxygen demand, and total coliform count were also determined (except for sample water from Ovwian (SW3), Electrical conductivity (EC), Total Hardness, Cl–, SO42-, NO3–, PO42-, Ca2+, Mg2+, BOD, COD, Cd, Zn and Cu were found to be below the desirable range recommended by WHO. The PH values range from 3.75 to 4.80 for the fourteen boreholes and 5.03 to 6.23 for the seven wells, indicating a predominance of acidic and slightly acidic water respectively. Total hardness values (mgl-1), Cl– (4 to 37.12), HCO3– (
