In the Nile Valley and Delta the protection of groundwater resources is high priority environmental concern. Many groundwater quality problems are already dispersed and may be widespread and frequent in occurrence. Examples include problems associated with the extensive application of chemical fertilizers in agricultural specially in the new reclaimed areas, leaks in sewers, septic tanks, the aggregate effects of many different points source pollution in urban areas and natural, geologically related water quality problems. A national groundwater quality monitoring has been designed and implemented based on the stepwise procedure. The national groundwater quality monitoring network is used to quantify the quality changes in long run, either caused by pollution activities or by salt water intrusion and to describe the overall current groundwater quality status on a national scale of the main aquifers. The monitoring tools and methodologies developed in this research can be used to assure protection of public health and determine the sustainability of groundwater in various purposes. This national monitoring network plays important roles for decision makers in developing the groundwater resources management plans in different aquifers systems in Egypt.
在尼罗河谷和三角洲地区，地下水资源保护是高度优先的环境问题。许多地下水质量问题已经出现并可能广泛且频繁发生。例如，与化肥在农业中的广泛使用相关的问题，特别是在新开垦地区；下水道、化粪池泄漏；城市地区众多不同点源污染的综合影响以及与地质相关的自然水质问题。基于逐步程序设计并实施了一项全国地下水质量监测。全国地下水质量监测网络用于长期量化由污染活动或海水入侵导致的质量变化，并在全国范围内描述主要含水层当前的总体地下水质量状况。本研究中开发的监测工具和方法可用于确保公众健康保护，并确定不同用途地下水的可持续性。这个全国性监测网络在埃及不同含水层系统的地下水资源管理计划制定中，对决策者起着重要作用。
