A national ranking of 333 cities for water quality
See your country on the red list or black list?
The so-called "national assessment of surface water section", it is according to the national surface water environment quality monitoring network set up "much starker choices-and graver consequences-in" plan "set the 2050 national assessment of surface water section, mainly distributed in the Yangtze river, Yellow River, pearl river, the songhua river, huai river, hai river, liao river basin such as southwest and northwest rivers, rivers and zhejiang fujian piece and so on three big area of major rivers and lakes.
In terms of specific calculation indexes, the ranking is in accordance with the requirements of "technical provisions on the ranking of urban surface water environmental quality (trial)", and adopts 21 indexes other than water temperature, fecal coliform and total nitrogen in table 1 of "surface water environmental quality standards" (gb3838-2002), which are consistent with the evaluation and assessment indexes of surface water.
Small make up from the overall list found that there are basically no first - and second-tier cities, because of the development of cities so the water quality of the first - and second-tier cities is getting worse, so the overall ranking without these cities.
The water quality ranking does not include urban groundwater, black and smelly water bodies, and smaller rivers, lakes or reservoirs that do not have national surface water assessment sections.
The ministry of ecology and environment also announced
The water environment in some areas is still up to standard
On May 7, the ministry of ecology and environment also reported the quality of China's water environment in the first quarter, as well as the achievement of targets and tasks. The overall quality of water environment in China has improved. Among the surface water evaluation sections in 1940 countries, 74.3% of the sections had excellent water quality, up 8.0 percentage points year on year. Worse Ⅴ section proportion is 6.0%, fell 3.6% year on year. The main pollution indicators are ammonia nitrogen, total phosphorus and chemical oxygen demand. The prevention and control of water pollution is unbalanced, and the water environment in some areas still meets standards.

Jilin, guangdong, guangxi, shanxi, shaanxi, gansu and other 6 provinces (area) water quality excellent (Ⅰ - Ⅲ class) proportion of water body, loss of function (inferior to Ⅴ class) two target timing schedule water ratio in the obvious gap between the annual target. Shanxi, liaoning provinces have 20 worse Ⅴ state-controlled section, tied for the provincial worse Ⅴ state-controlled section number first.
Hu said that by making the ranking information public, the public's right to know, participate in and supervise the environment can be guaranteed, the national water ecological and environmental protection can be accelerated, local water pollution prevention and control responsibilities can be implemented, and the level of drinking water safety can be continuously improved.
Three drinking water safety and then ring the alarm!
According to statistics, on average, 25,000 people die of various diseases caused by drinking water every day. Domestic environmental pollution is becoming more and more serious. Industrial, agricultural and domestic pollution has led to the pollution of 90% of rivers. Drinking water with excessive amounts of e. coli is up to 900 million, drinking water with excessive amounts of iron is up to 380 million, consuming oxygen is up to 200 million, drinking water with excessive amounts of fluorine is up to 9.48 million...
Therefore, if drinking water is not thoroughly filtered and sterilized, viruses and parasites can enter the human body directly through drinking, and thus reside in the body, posing a threat to life safety.
Since raw water cannot be drunk directly, is that safe to drink after boiling tap water? Not so. Tap water factory is generally up to standard, but after a long distance to the user's home, unavoidably secondary pollution.
Boiled tap water, although can kill microorganisms, but can not solve the problem of organic pollutants and heavy metal ions, it is difficult to ensure the health of drinking water.
