Abstract
Water is one of the abundantly available substances in nature. It is a vital factor for aquatic life as well as for human use. In this report, water samples were collected from Orwell International Oil and Gas Nigeria limited (both borehole water, drainage water and Cway water) all were analyzed for their major, minor and trace metals element constituents and physiochemical parameter, using modern analytical methods. The results were evaluated with a view to determine and compare the quality of the water sampled from the study area with WHO Standard to enable us knows the quality of water in the industrial layout. The following physiochemical and heavy metals were analyzed with concentration level range as follow: Total dissolved solid “TDS” ranged from 20.0 – 250 mg/l with mean value as 123.33 mg/l), Total suspended solid “TSS” ranged from 12.0 – 130 mg/l with mean value as 51.33 mg/l, Total hardness ranged from 8.0 – 32.02 mg/l with mean value as 18.67 mg/l, Conductivity ranged from 7.0 – 46.0 µs/cm with mean value as 26 µs/cm, pH ranged from 4.21 – 7.21 with mean value as 6.06, Dissolved oxygen “DO’’ ranged from 4.80 – 5.60 mg/l with mean value as 5.067 mg/l, Biochemical Oxygen Demand “BOD” ranged from 15.0 – 30 mg/l with mean value as 20.833 mg/l, Salinity ranged from 15.40 – 35.91 mg/l with mean value as 25.56 mg/l, Iron “Fe” ranged from 0.088 – 3.396 mg/l with mean value as 1.21 mg/l, Pb ranged from 0.014 - 0.047 mg/l with mean value as 0.0143 mg/l, Zn ranged from 0.065 – 0.159 mg/l with mean value as 0.125 mg/l, Cd ranged from 0.006 – 0.013 mg/l with mean value as 0.0006 mg/l and Ni ranged from 0.015 – 0.140 mg/l with mean value as 0.0743 mg/l. The mean values for TDS, TSS, Conductivity and Salinity were below the WHO Standard for portable drinking water, while the total hardness and dissolved oxygen falls within the WHO Standard limit. The BOD was above the WHO Compliance limit for portable drinking water, although the pH for the Cway water fall within the WHO permissible limit for portable water but the pH for borehole water is below the WHO permissible limit for portable water. The presence of some heavy metals (Zn, Pb, Cd, Fe, Ni) were also detected in the analysis which will be toxic to human being and the environment at high concentration.
