How to protect family drinking water

In recent years, China's urban water pollution control and drinking water supervision and management efforts continue to increase, but still not fully solve the problem of drinking water insecurity. According to the research results of the Ministry of Environmental Protection, there are polluting enterprises such as petrochemical, coking, and thermal power generation within 1 km of China's 110 million residential buildings, and 280 million residents use unsafe drinking water. So, how to protect the safety of family drinking water?
According to the statistics of the National Development and Reform Commission, by 2017, although the country has invested a lot of manpower, financial resources and material resources in household drinking water equipment, the quality of drinking water in the family is still very serious. The quality compliance rate of drinking water in urban households in China is about 65%, and the quality compliance rate of drinking water in rural households is about 56.1%. Therefore, how to ensure the safety of family drinking water has become a topic of great concern to the society.
1. The main reason is that due to imperfect water pipeline facilities and too few water treatment equipment factories, many remote rural areas are still drinking river water and well water, which seriously threatens people's health. 2. Secondly, river pollution, surface water pollution and groundwater pollution caused by pesticides, fertilizers, heavy industries, economic development, etc., lead to the safety and quality of drinking water in the country is generally not up to standard. 3. Even if the tap water can reach the current standard when it leaves the factory, in the process of transportation, the facilities of the water supply pipe network are outdated, affected by the rust and microbes of the pipe network, resulting in the safety of the user's drinking water.
Heavy metals cannot be decomposed in water, and when people drink it, the toxicity is amplified, and combined with other toxins in the water to produce more harmful substances. Heavy metals can cause headaches, dizziness, insomnia, joint pain, stones, etc.; especially for the digestive system, cells of the urinary system, organs, skin, bones, nerves are extremely serious. The water quality is excellent, mainly due to high calcium and magnesium ions, and easy to deposit. Regular consumption of hard water can lead to an increase in the incidence of kidney stones, and can also harm the human digestive system, causing gastrointestinal disorders, damage to the kidneys and cardiovascular and cerebrovascular diseases. In particular, the development of young children is not complete and may affect the development of the digestive system. Organic pollution and heavy metal pollution have replaced microbial pollution and become the biggest hazard for drinking water safety in China. According to a research report issued by the US Environmental Protection Agency, the existing detection technology found that there are 756 organic compounds in drinking water, including 20 carcinogens, 23 suspected carcinogens, 18 carcinogens and 56 mutagens. At present, the national standard requires less than 0.1 mg per liter of nitrite, while the International Codex Alimentarius Standard for Natural Mineral Water is less than 0.02 mg, which is more stringent. A small intake of nitrite can cause hypoxia poisoning in humans. Those who are dizzy and faint are stunned or even die. Long-term micro-intake can increase the risk of cancer in humans. Drinking water needs to be tested for microbial indicators, such as Escherichia coli, heat-resistant coliforms, Giardia, and Cryptosporidium; if these indicators are unqualified, bacterial infections and parasitic diseases are likely to occur. It causes gastrointestinal symptoms such as abdominal pain and diarrhea.
