本篇論文代筆-水問題討論了水質方面對確保水安全起着非常重要的作用。自從水問題造成的死亡事件觸痛了一般公衆以來，越來越多的人對有效維持生命支助系統的重要性迅速提高。上圖代表了導致水質惡化的各種關鍵因素和途徑。loop R1代表的是城市區域的擴張如何惡化水的質量(Sachin et al . 2017, pp.1076-1087)。爲了給新一代或移民提供住宿設施，將需要更多的土地來提供住房服務，這造成了更多的水文干擾。本篇論文代筆文章由新西蘭第一論文Assignment First輔導網整理，供大家參考閱讀。
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.
From the loop R3 and R2, it can be proposed that the quality of water can be improved using the possible technologies in order to reduce or minimise the hazards and wastes. The reuse of storm water harvesting has been proved as the best measure in order to mitigate the possible effects on the water quality from the urban runoffs (Chang et al 2015). The technologies like water urban design for sensitiveness (WUSD) can enable restoring soil properties utilising the integration of different storm water technologies for harvesting into the design of urban landscape. Due to this, the key impacts from the urbanization on the quality of water will be significantly reduced and at some point of time will be finally eliminated. It has been analysed from different studies or researches that it will require more time in order to build efficient scheme for reuse of storm water due to high costs and limitations within the current technology.
From the loop B1, it is cleared that growth of the industrialisation is also affected the quality of water using the other intermediate variables as observed in the casual loop diagram. It is not very fair to neglect all the benefits obtained from the industrial development. Nevertheless, in recent times, industrialisation is the main factor viewed for the cause of water pollution. The rapid use of different chemicals within industrial processes is reducing effluent’s quality and also narrowing further alternatives for their use. The industrial activities are degrading the quality of water at the lowest level which is posing severe threat on the health of human beings rather than its consumption (Bala et al 2017, pp. 37-51). In addition, inadequate environmental acts or regulations and less monitoring on industrial activities, industrialists are emphasised to discharge water effluents on direct basis to the water received without processing any treatment for waste water in order to achieve their objective of overall minimised costs. It has been evident from various researches that chemicals contained within water bodies are of hazardous nature and pose severe threat on health of humans when consumption of water takes place which causes serious health consequences and deaths in specific cases. It has been predicted that more than 135 million humans will die due to water borne diseases by the end of 2020. The devastating problems related to human health will shock the entire globe, shake social balance and as the result will subsequently impede social and industrial development.
