摘要

摘要:本研究评估了卡杜纳州奇昆地方政府地区的地下水质量,以及如何将其作为一种有用的供水资源加以利用,并改善水资源管理。数据采集采用实地调查法,实地采集水样。本研究在两年(2021-2022年)的干湿季节高峰期间,在赤昆地方政府辖区内选定的五个区随机采集了50个水井和钻孔水样,测量了一系列水质参数,并与世卫组织饮用水标准进行了比较。实验室分析结果显示,除镁、汞、铁、铅和钙外,其他物理化学参数均在最大允许范围内。其中一些污染物的存在程度不同。地下水模型显示地下水向西北方向流动,污染物在深度约60 m处有明显的垂直运动。这就要求制订关于处理影响地下水的废物和污染物的条例,最好通过严格执行法律和通过所有有关的水管理机构进行宣传来做到这一点。

Hydro-geochemical characterisation and modelling of groundwater in Chikun Local Government Area of Kaduna state, Nigeria
Abstract This study assessed groundwater quality in Chikun Local Government Area of Kaduna State and how it can be harnessed as a useful resource for water supply and to improve the management of water resources. The field survey methods adopted with the collection of water samples in the field were employed in collecting data. The study randomly collected fifty water samples from wells and boreholes in the peak of wet and dry seasons for 2 years (2021–2022) in the five selected wards within the Chikun Local Government Area and a range of water quality parameters were measured and compared with WHO standards for drinking water. The laboratory analysis results revealed that with the exception of magnesium, mercury, iron, lead and calcium, all other physicochemical parameters measured fell within the maximum permissible limit. The presence of some of these pollutants at varying degrees was found. Groundwater models showed groundwater flow in the North-Western direction and significant vertical movement of contaminants up to depths of about 60 m. This calls for regulations on the handling of wastes and pollutants that affect groundwater, which is best done through strict enforcement of laws and advocacy through all the appropriate institutions involved in water management.
