Groundwater is one of the most valuable natural resources in the world, and, a limited resource, particularly for Namibia. For this reason, this resource should be protected and monitored on a regular basis for sustainability. One of Sustainable Development Goals (SDGs) aims to ensure availability and sustainable management of water and sanitation for all with specific emphasis on data and good governance. Therefore, this study was conducted in the Kuiseb Basin, Namibia to assess the physical and chemical quality of groundwater, chemical water type and chemical characteristics of sediment to determine its suitability for human consumption. Water and sediments samples from 20 sampling sites (boreholes) were analysed for physical and chemical characteristics and the following mean values were obtained for temperature (26.66 °C), electrical conductivity (396.85 mS/m), pH (7.26), total dissolved solid (494.45 mg/L) and dissolved oxygen (7.46 mg/L). Physico-chemical results suggest that the Kuiseb Basin is predominantly a calcium bicarbonate water type (Ca (HCO3)2) and most of the physico-chemical parameters tested fell within the permissible limits for drinking water set by the World Health Organisation (WHO). Analysis of the major ion chemistry (Mg²⁺ > + Ca²⁺ > + Na+ > + K+ and HCO³⁻ > CO³⁻ > SO4 ²⁻ > Cl⁻) indicated the dominance of rock-water interaction and the influence of anthropogenic activities as the main process controlling groundwater chemistry in the area. It is recommended that the Basin, as a heavily used and sensitive environment, requires basin-wide river management.

地下水是世界上最有价值的自然资源之一，并且是有限的资源，特别是对于纳米比亚而言。因此，应定期保护和监视此资源以实现可持续性。可持续发展目标（SDG）之一旨在确保所有人的用水和卫生设施的可用性和可持续管理，并特别强调数据和善政。因此，这项研究是在纳米比亚的Kuiseb盆地进行的，旨在评估地下水的物理和化学质量，化学水的类型以及沉积物的化学特征，以确定其对人类消费的适宜性。分析了来自20个采样点（钻孔）的水和沉积物样品的理化特性，并获得了以下温度平均值（26.66°C），电导率（396.85 mS / m），pH（7.26），总溶解固体（494.45 mg / L）和溶解氧（7.46 mg / L）。理化结果表明，库伊布盆地主要为碳酸氢钙水类型（Ca（HCO3）2），测试的大多数理化参数都在世界卫生组织（WHO）设定的饮用水允许范围内。主要离子化学分析（镁²⁺  > +的Ca ²⁺  > +的Na +> + K +和HCO ^3-  > CO ^3-  > SO 4 ^2-  >氯^- ）表明岩石-水相互作用的主导地位和人类活动为主要过程控制地下水化学的影响在那地区。建议将该流域作为一个频繁使用且敏感的环境，要求对整个流域的河流进行管理。
