在撒哈拉以南非洲，45%的农村人口使用井眼。尽管最近在改善供水和供水覆盖面方面取得了进展，但平行使用未经改善的水源的情况依然存在。基础设施的周期性失修造成了房舍的非专用性使用。我们的研究描述了加纳东部地区15个农村城镇2014年、2015年和2016年BH的功能，这些城镇的地下水来自三个地下水质量集群（高铁、高盐和控制）。我们还使用逻辑回归评估影响横截面和纵向功能的因素。BH功能率范围在81%至87%之间，并且在地下水质量群中相似。在所有三年中评估的51个BH中，34个（67%）功能稳定，只有3个（6%）持续断裂。在对照组和高盐度组的研究过程中，出现了向主动支付水的转变。支付机制，人口服务，附近的替代水源的存在，地下水水质集群的横截面或纵向BH功能没有显着的预测。然而，即使在高铁集群，水质差，没有结构化的水支付机制的存在，BH被维持，表明他们是重要的社区资源。
In sub-Saharan Africa, 45% of the rural population uses boreholes (BHs). Despite recent gains in improved water access and coverage, parallel use of unimproved sources persists. Periodic infrastructure disrepair contributes to non-exclusive use of BHs. Our study describes functionality of BHs in 2014, 2015, and 2016 in 15 rural towns in the Eastern Region of Ghana sourced from three groundwater quality clusters (high iron, high salinity, and control). We also assess factors affecting cross-sectional and longitudinal functionality using logistic regression. BH functionality rates ranged between 81 and 87% and were similar across groundwater quality clusters. Of 51 BHs assessed in all three years, 34 (67%) were consistently functional and only 3 (6%) were consistently broken. There was a shift toward proactive payment for water over the course of the study in the control and high-salinity clusters. Payment mechanism, population served, presence of nearby alternative water sources, and groundwater quality cluster were not significant predictors of cross-sectional or longitudinal BH functionality. However, even in the high iron cluster, where water quality is poor and no structured payment mechanism for water exists, BHs are maintained, showing that they are important community resources.
