The present study examined some physico-chemical characteristics (temperature, pH, total hardness, dissolved oxygen (DO), total dissolved solid(TDS), conductivity, transparency, biochemical oxygen demand (BOD), acidity and alkalinity) and some heavy metals (Fe, Zn, Cu, Cd, Cr and Ni) concentration of Stubbs Creek, Ibeno, Akwa Ibom, Nigeria between August 2014 and July, 2015. Six sampling stations (Mkpanak, Okpot Ikot, Ebana Mbri, Esit Eket, Okpuk and Ikot Ebia Anam) in Stubbs Creek were selected. Water samples were analyzed using APHA-AWWA-WPCF methods while heavy metals in the water samples were digested and determined using UNICAM 939 Atomic Absorption Spectrophotometer (AAS). The mean values of water parameters of Stubbs Creek are: temperature (27.22 ± 0.230C); pH (6.83 ± 0.13), DO (3.86 ± 0.20 mg/L), BOD (2.84 ± 0.11 mg/L), conductivity (522.23 ±69.12 µScm-1), TDS (288.83 ± 39.50 mg/L), transparency (0.86 ± 0.05m), alkalinity (95.51± 6.44mg/L), acidity (97.03±7.45) and total hardness(12.11±1.55).Only TDS, conductivity, alkalinity and total hardness showed significant (p |
