Evaluation of Water Sources Situation in Offa Local Government Area of Kwara State, Nigeria

Background: The objective of this study was to investigate the geospatial analysis of underground water resource management and distribution pattern of water supply in Offa, Kwara State, Nigeria. A case study was carried out for the study area.

Methods: Data were collected from two wells in the area. The cumulative values for the variables were collected twice daily for a period of nine months beginning from January to September 2014 for the wells. The data were analyzed by using systematic random sampling technique. The linear regression was used to check the relationship between two variables while the multiple regression analysis was also used as a descriptive analysis tool or as an inferential tool by which the relationship in the total population was evaluated and determined.

Results: The study revealed that despite the government efforts and those of the various agencies, there was still a great reliance especially in the rural areas, on polluted sources of water which make the inhabitants vulnerable to diseases and epidemics which can lead to sudden death if not check-mated.

Conclusion: This research demonstrated that there was a significant reliance, especially in rural areas in the study area, on water sources which make them vulnerable to epidemics.

背景：本研究旨在探究尼日利亚夸拉州奥法地区的地下水资源管理空间分析与供水分布格局，以该区域作为案例研究对象。

方法：本研究从区域内2口监测井采集数据。2014年1月至9月的9个月周期内，每日分两次采集各变量的累积值。数据分析采用系统随机抽样技术，其中线性回归用于检验双变量间的关联关系，多元回归分析则兼具描述性与推断性分析功能，用于评估并确定总体人群中的关联特征。

结果：研究表明，尽管尼日利亚政府及各相关机构已开展相关工作，但研究区域尤其是农村地区仍高度依赖受污染的供水水源，致使当地居民易感染各类疾病与流行病，若未及时采取防控措施，甚至可能引发突发死亡。

结论：本研究证实，研究区域尤其是农村地区仍显著依赖受污染水源，致使当地居民易受流行病侵袭。
