在确保水安全方面，质量方面起着非常重要的作用。由于水问题造成的死亡事件已经影响到公众，因此，在更多的人身上，水质量的重要性迅速增加，用于维持生命的支持系统。上述数字代表了导致水质恶化的各种关键因素和途径。环路R1代表了一个事实，即水的质量如何随着城市地区的扩张而恶化(Sachin et al 2017,pp.1076 – 1087)。为了给新一代或新移民提供住宿设施，提供住房服务需要更多的土地，这将导致更多的水文骚乱。从不同的研究中分析，水的质量受到了土地集约化的影响。还分析了由于土壤缺勤和植被损失，自然净化的过程，如利用未铺设的土壤过滤，以及植物或微生物对生物的吸收。此外，水污染物的积累以及径流减少了不同水资源或水体的水质。
The quality aspect plays very huge role in ensuring the water security. The significance for the water quality has been rapidly increased among more amounts of people for efficient maintenance of life supportive systems since the incidents of deaths from the water issues have stroked the general public. The above figure is representing the various key factors and pathways which are causing deterioration for the water quality. The loop R1 is representing the fact that how the quality of water is deteriorated by the expansion from the urban areas (Sachin et al 2017, pp.1076-1087). In order to provide accommodation facilities to new generation or immigrants, more land will be required for providing housing services which is causing more hydrological disturbances. It has been analysed from the various studies that quality of water is hugely affected from the intensive usages of lands. It has been also analysed that processes of natural purification like filtration using the unpaved soils and biological uptake from plants or microorganisms are reduced because of soils absences and vegetation losses. In addition, accumulation by the water contaminants as well as runoffs is reducing the quality of water for the different water resources or bodies.
