Abstract

The purpose of the study is to examine the spartial analysis of groundwater using geographic information system and water quality index (WQI) in the study area. Fifty (50) water samples were collected and analysed in accordance to APHA, 2012. The data-set were further analysed using water quality index (WQI) and geographic information system (GIS). The results of the indicate that Igbogene 1, Yenagwe 1 & 2, Akenfa 1, Ekeki 1, Yenizue-Epie 1, Swali 1, Igbogene 2, Akenfa 2, Agudama 1 & 2, Etegwe 2, Opolo 1 & 2,Yenizuepie 2, Swali 2, Akaba 2, Ogu 2, Akaibiri 2, Gbarantoru3 & 5, Ogbuna 1, 3 & 4, Okolobiri 1, 2, & 5 and Tombia 2 & 4, water quality index shows that the quality ranges from poor to very poor. While the samples, Yenigwe 1, Biogbolo 1, Kpansia 1 & 1, Amarata 1, Ogbogoro 1, Ogu 1, Akaba 1,Okutukutu 1, Kpansia3, Amarata 2, Ogbogoro 2,Akaibiri 1, Gbarabtoru 1, 2 & 4, Ogbuna 2, Okolobiri 3 & 4 and lastly, Tombia 1 & 3 all ranges from good, very good to excellent water quality. However, the study shows a very                     high spartial variation in water quality. Therefore, groundwater should be regularly monitored and treated.
