    This research assessed effects of oil spill on water quality in Gokana Local Government Area of Rivers, Nigeria. Oil spill is inarguably the most important type of pollution in the Niger Delta region. The objectives of this study were to assess the quality of surface water in the study area and compare it with the World Health Organization Standard for domestic water uses This study selected ten (10) communities (Barako, Bodo, Deken, Gbe, Goko, Kibangba, Lewe, Mogbo, Nugbeio, and Yeghe) based on outstanding oil spill incidents in these communities for data collection which involved collection of water samples for laboratory test. The result shows that the Total Hydrocarbon (THC) content of the water samples was high and above regulatory limit and that water quality parameters such as temperature , carbon dioxed (CO2), chemical oxygen demand (COD), biological oxygen demand, total hydrocarbon content (THC) are beyond the WHO permissible limits while parameters such as pH, dissolved oxygen(D.O), are below the WHO limit. It was concluded that oil production in the region can only be sustainable environmentally, economically and socially if the oil companies should be more environmental conscious and follow strictly the provisions of law and standards set by regulatory

    EVALUATION OF THE IMPACT OF GURARA DAM ON SURFACE WATER QUALITY WITHIN THE CATCHMENT IN KADUNA STATE, NIGERIA.
    (Environmental Science Department, Nasarawa State University, Keffi., 2018-01-13) Abugu, N.A.; Yero, A.B.; Daku, Y.S.; Patrick, N.O.
    77715 study evaluates Gurara dam impact on water quality within the catchment. Its objectives were to assess the quality ofs urface water within Gurara dam catchment area and compare the quality of surface water in the EIA baseline data with the present surface water quality. The result of this research work was gathered through laboratoty analysis of water samples collected within Gurara dam catchment. Data collected were analsysed using mean, range, coefficient of variance and student V test. This study found that all water quality parameters measured were within National Environmental Standards and Regulations Enforcement Agency (NESREA) limits for irrigation except for DO, BOD and COD; all surface water quality parameters have lesser calculated 7’ values than critical values expect for BOD. Therefore, Ho is accepted for all parameters expect for BOD, so there is no significant difference in the water quality parameters (temperature, pH, turbidity, total dissolved solid, total suspended solid, total solid, dissolved oxygen, COD) expect BOD. Although, all surface water quality parameters vary between the EIA and the present surface water quality but only BOD changed significantly. Since the present surface water samples have higher mean of BOD than the EIA baseline data, BOD has increased significantly after the dam construction. It was concluded that dam have significant negative impacts on water quality as BOD have been altered significantly after dam construction. Thus this study
