Physicochemical analyses of surface and groundwater samples from eleven different locations in Ugbomro and Iteregbi, Delta State, Nigeria were sampled and analyzed for physicochemical parameters according to standard methods for the examination of water and wastewater. The following mean and standard deviation were obtained from the groundwater of the communities: temp (oC) 22.46 ± 0.50 and 23.23 ± 0.99, pH 6.63 ± 0.68 and 6.69 ± 0.24, dissolved oxygen (DO) (mg/L) 5.91 ± 0.46 and 5.73 ± 0.46, chemical oxygen demand (COD) (mg/L) 4.24 ± 0.01 and 4.43 ± 0.10, biochemical oxygen demand (BOD) (mg/L) 3.51 ± 0.38 and 3.84 ± 0.21, Turbidity (NTU) 1.22 ± 1.07 and 3.56 ± 0.77, electrical conductivity (EC) (μs/cm) 748.9 ± 215.79 and 786.67 ± 226.77, color (TCU) 1.22 ± 2.12 and 6.11 ± 2.11, total alkalinity (TA) (mg/L) 6.22 ± 7.38 and 14.11 ± 11.19, HCO3- (mg/L) 6.22 ± 7.38 and 14.11 ± 11.19, NO3- (mg/L) 1.13 ± 0.62 and 2.89 ± 1.25, total solids (TS) (mg/L) 489.09 ± 180.17 and 664.95 ± 373.37, total suspended solids (TSS) (mg/L) 32.25 ± 24.29 and 123.86 ± 82.79, total dissolved solids (TDS) (mg/L) 456.78 ± 163.73 and 542.20 ± 450.66, Cl- (mg/L) 21.20 ± 3.20 and 20.10 ± 3.89, total hardness (TH) (mg/L) 26.67 ± 22.83 and 46.78 ± 36.17, Na (mg/L) 1.26 ± 0.06 and 1.16 ± 0.04, K (mg/L) 0.04 ± 0.01 and 0.06 ± 0.03, Mg (mg/L) 4.32 ± 3.23 and 6.96 ± 5.49, Ca (mg/L) 8.68 ± 9.35 and 18.12 ± 13.71 respectively. The results obtained were subjected to statistical analysis and compared with the standard set by the Standards Organization of Nigeria (SON) and the World Health Organization (WHO) for water samples. Some of the parameters did not meet the standards, hence the need for treatment. The present physio-chemical analyses of surface and groundwater quality of the two neighboring university areas, Ugbomro and Iteregbi, were done to assess the environmental status of the environment before socio-economic impacts.
