    Effects of Gas Flaring and Oil Spillage on Rainwater Collected for Drinking in Okpai and Beneku, Delta State, Nigeria
    (Department of Geography, Nasarawa State University Keffi, 2012-01-09) Dami, H.K.; Ayuba, H.K.; Amukali, O.
    This paper evaluates the effects of gas flaring and oil spillage on rainwater quality for domestic use in Okpai and Beneku areas of Delta State, Nigeria. Both field and laboratory techniques were employed in the analyses of rainwater quality. Rain water samples were collected in the dry (December, January and February) and wet (June, July and August) seasons from Okpai (experimental site) and Benekuku (controlled site). The water samples were analyzed for chemical, physical and biological parameters using the methods of Radojevic and Bashkin, 1976; USEPA ,2007; and Kolo, 2007.The results showed that gas flaring and oil spillage have significantly changed some physic-chemical and biological properties of drinking water in the study area. For instance, there were changes in the taste, color, temperature, conductivity, alkalinity and total dissolved salts. These could have serious health implications on the ihabitants of the area. Apart from these, other parameters analyzed corresponded to the approved maximum permissible limits for drinking water set by NAFDAC, USEPA and WHO.

    Ground water pollution in Okpai and Beneku, Ndokwaeast local government area, delta state, Nigeria
    (Department of Geography, Nasarawa State University Keffi, 2013-02-21) Dami, A.; Ayuba, H.K.; Amukali, O.
    This study has assessed the probable contamination of ground water resources in Okpai and Beneku area of Delta State, Nigeria. The ground water samples were collected in the dry season (December, January and February) and wet season (June, July and August) seasons from Okpai (experimental site) and Beneku (control site). The water samples were analyzed for Physico -Chemical and biological parameters using standard procedures. The results show that both Okpai and Beneku ground water contained high amounts of magnesium (1.173mg/l in the dry season and 1.277mg/l in the wet season) and iron (0.036mg/l in the dry and 0.021mg/l in the wet) for the former while cadmium (0.002mg/l in the dry and 0.005mg/l in the wet), iron (0.676mg/l in the dry and 1.062mg/l in the wet), magnesium (1.21mg/l in the dry and 1.437mg/l in the wet) and lead (0.004mg/l in the dry and 0.005mg/l in the wet) for the latter. Apart from these specific cases, other values corresponded to the approved maximum permissible level (i.e. maximum permissible limits for drinking water set by NAFDAC, USEPA and WHO). The ground waters therefore, were more impacted upon by chemical parameters, than physical and biological parameters. In conclusion, this study recommends for the Bio- Physico-Chemical assessment extension to other new areas of the Niger Delta region of Nigeria.

    Physico-Chemical and Bacterialogical Analysis of the Surface Water Used for Domestic Purposes in Okpai and Beneku, Delta State, Nigeria
    (Department of Geography, Nasarawa State University Keffi, 2012-01-01) Dami, A.; Ayuba, H.K.; Amukali, O.
    The main focus of this study is to analyze the effects of gas flaring and oil spillage on surface water used for domestic purpose in Okpai and Beneku area, Delta State Nigeria. Surface water samples were collected in the dry (December, January and February) and wet (June, July and August) seasons from Okpai (experimental site) and Beneku (control site). The water samples were analyzed for chemical, physical and biological parameters using standard procedures. The results for all the parameters analyzed showed higher variation between samples obtained from the experimental site and those of the control site which indicate possible pollution in the experimental site for instance, the pH values were 5.33 and 5.586 in the dry and wet seasons respectively for Okpa. For Beneku, the pH values were 6.82 and 6.91 in the dry and wet seasons respectively. Magnesium (2.437mg/l in the dry and 2.063mg/l in the wet recorded in samples obtained from Okpai were higher than those obtained Beneku. The presence of coliform (<2 colonies in the dry and approximately <1.67 colonies in the wet were recorded in Okpai samples.
