近年來,環境污染問題已被世界廣泛關注。無論是水污染還是土地污染,它已經嚴重影響了世界。水污染可以定義為由於有害物質的存在而造成的水污染。人們喝的水是人們最重要的成分之一,有助於滿足他們的生活。然而,水污染問題是每個國家都能看到的。根據世界衛生組織進行的研究,已經發現世界上大約有六分之一的人口得不到適當的安全飲用水。此外,約有24億人缺乏基本的衛生設施。水污染最有害的影響是它由許多有害的廢水、污水、雨水和被農業污染的水組成。而且,很多時候被污染的水是無法被普通人識別的。

The problem of environmental pollution has been largely observed by the world in recent years. Be it the water pollution or the land pollution, it has been badly affected the world. Water pollution may be defined as the contamination of water because of the presence of unwanted substances. The water drunk by the people is one of the most important ingredients for people and helps to cater for their life. However, the problem of water pollution is something which is observed in each and every nation. According to the research conducted by WHO, it has been found that around one sixth of the entire population in the world does not get the proper water which is safe for drinking. Also around 2.4 billion people lack the basic sanitation. The most harmful impact of polluted water is that it consists of a number of harmful effluents, sewage water, rain water and the water which is polluted by agriculture. Also, many times the polluted water is unrecognizable by the common people.

According to the estimates, it has been found that around fifty countries in the world have to face the problem related to the water pollution and the people in around 20 million hectare in the world are exposed to the partially treated water. This poorly treated water is harmful and leads to a number of health related hazards and the death of human beings, aquatic life and also disturbs the production of crops to a large extent (Kneese, 2015). The effect of water pollution is so harmful that it becomes the leading cause of death for a number of people across the globe. In addition to this, polluted water also harms and affects the oceans, lakes, rivers and raises a global concern for the world. Besides this, it also leads to the death of aquatic life. Also the polluted water consists of a large amount of fluoride content whose range is from 5.26 to 26.32 milligrams per liter which is much higher than the standard content of 0.6 to 1.7 milligrams as set by World Health Organization.
