ASSESSMENT OF THE PHYSICOCHEMICAL WATER QUALITY COMPLIANCE OF WUPA WASTEWATER TREATMENT PLANT, FOR DOMESTIC USE IN FEDERAL CAPITAL TERRITORY, ABUJA NIGERIA

This study assessed the Physicochemical Water Quality Compliance of Wupa Waste Water treatment Plant for Domestic use in Federal Capital Territory Abuja, Nigeria. The aim was achieved through the following objectives: Determine the physicochemical properties of the water in WUPA waste water treatment. To determine the suitability of water discharged from Wupa treatment plant for domestic water use. Methodology, the study was anchored on qualitative research design. Analysis was carried out in the laboratory and the result obtained from the test were qualitatively compared with the recommended water quality standard. Parameters analyzed include: pH, Temperature, Total Dissolved Solid (TDS), Total Suspended Solid (TSS), Biochemical Oxygen Demand (BOD), Dissolved Oxygen (DO), Chemical Oxygen Demand (COD), Chloride, Sulphate, Oil and Grease. The study revealed that the result of the selected physicochemical parameters when further compared to world Health Organization \TOO (2007) and NESREA (2011) Standard limit for drinking water showed that all parameters for treated waste water (effluent) are within the permissible limits for drinking water, except for DO (6.81 mg/I) BOD (37.3mg/l) and Oil/Grease (13.2mg/l) compared to WHO limits of DO (2mg/l), BOD (34mg/l) oil/grease (10mg/l) indicate a slight differences in the BOD and Oil/Grease from the standard limits set by WHO. The result of physicochemical parameters for each sample were analyzed using simple descriptive statistics of mean, standard Deviation, and standard error of the mean. The mean score of each analyzed parameter from each sampling point was compared with the various permissible limits set by Federal Environmental Protection Agency FEPA (1991) and national environmental Standard and Regulation Enforcement Agency (NESREA) 2011 in order to determine the rate of environmental degradation and compounded health hazards associated to the discharge of Wupa treatment Plant. Thus more effort should be put in the treatment of influent waste water generated in the F.C.T before discharge into receiving streams, people using the water downstream of the river Wupa must treat it or boil it thoroughly and filter before drinking and putting to other domestic usage.
