Physico-Chemical and Bacterialogical Analysis of the Surface Water Used for Domestic Purposes in Okpai and Beneku, Delta State, Nigeria
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.
