26,895 Boston marathon runners ran miles on the street. Whenever the runner feels tired, they will run sideways and then suddenly drink a cup of fresh and clean water. However, not everyone in America has such clean drinking water. The country has about 55,000 community water supply systems to meet the drinking needs of over 90% of the US population. The Environmental Protection Agency (EPA) defines community sources as supplying at least 25 percent of water for at least 60 days in a year.
Every country around the world strives to keep drinking water clean. Whether it is a stream or a river or a lake, the country has taken a big step to maintain high quality drinking water for human consumption and consumption of animals. Each country must first understand the cause of pollution and then decide on the best way to eliminate it. Clean drinking water is a precious resource, and the key to human survival. Since plants and animals also depend on the growth of water, it is necessary to keep all the water clean. The major causes of water pollution can be classified into three categories: industry, agriculture and local government.
Water pollution is one of the main threats to public health in Pakistan. Poor quality control and drinking water monitoring Pakistan is ranked 80th in the drinking water quality among 122 countries. Surface water and groundwater drinking water sources are polluted by coliform bacteria, toxic metals and agricultural chemicals nationwide. Various drinking water quality parameters set by the World Health Organization are often violated. Artificial activities such as improper treatment of municipal sewage and industrial waste water and indiscriminate use of agricultural chemicals in agriculture are the main causes of deterioration of water quality. Microorganisms and chemical contaminants are a major factor in the major causes of various public health problems or a combination thereof. This review explains the detailed layout of the quality of drinking water in Pakistan, with particular emphasis on major pollutants, sources of pollution, and the resulting health problems.
The WHO has developed a series of water quality guidelines, including safe use of drinking water, drainage, and a safe entertainment water environment. Since 2004, the water quality guidelines for drinking water include a water safety program to identify and prevent risks before water pollution. Since 2014, WHO has tested household water purification products on WHO health-based performance standards through the World Health Organization's "plan" to assess household water purification technology. The purpose of this program is to ensure that the product protects users from pathogens causing diarrheal diseases and to support national-level policies, regulatory and monitoring mechanisms to support the proper use and consistent proper use of such products It is to strengthen.
