Abstract

Abstract Groundwater is a major resource for drinking water, especially in developing countries, where it is less expensive to treat than surface water. Today, the resource is highly susceptible to pollution, particularly as a result of human activity. This review was based on a literature review and critical analysis of models for estimating the groundwater vulnerability. The results show that the deepest porous aquifers are the least susceptible to pollution, whereas those in karstic and fissured environments are susceptible, whatever their depth. Pollution usually arises from human activity. Critical analysis of the literature shows that existing methods are developed in specific environmental contexts. Given the variability of factors in space and time, these methods do not take the intrinsic realities of all natural settings into account adequately and are not perfectly applicable in all environments. This highlights the need to develop appropriate models for each environment, such as that of the highlands in countries such as Cameroon.

估计高原地区地下水资源对弥漫性污染的脆弱性:文献综述和批判性分析(喀麦隆高地)
地下水是饮用水的主要资源,特别是在发展中国家,处理地下水比处理地表水要便宜。今天,这一资源极易受到污染,尤其是人类活动造成的污染。本综述基于文献综述和对地下水脆弱性评估模型的批判性分析。结果表明,最深的多孔含水层最不容易受到污染,而岩溶和裂隙环境的含水层最容易受到污染,无论其深度如何。污染通常由人类活动引起。对文献的批判性分析表明,现有方法是在特定的环境背景下发展起来的。鉴于空间和时间因素的可变性,这些方法没有充分考虑到所有自然环境的内在现实,并不完全适用于所有环境。这突出表明需要为每一种环境开发适当的模式,例如喀麦隆等国家的高原环境。
