According to the relevant regulations of the state, only half a year of all tests are needed to detect whether benzene exceeds the standard. Benzene has been found occasionally during annual testing of drinking water equipment in semi-schools. How long has it been since benzene contaminated drinking water? According to Veolia, it is now possible to determine that drinking water was not contaminated by benzene until at least March 8. It is impossible to verify when it will be contaminated after all until 17 April when benzene exceeded the standard.

Brother, please note that the water samples detected to exceed the standard of benzene were taken on April 2. Obviously, by April 11, Lanzhou citizens had drank at least nine days of serious excessive benzene water, and the longest time they could was 34 days. More seriously, according to the rule of semi-annual all-in-all testing, all-in-all testing has been completed on March 8, so the next time to detect benzene is September 8. The reason for the policy of testing benzene content in April is that the factory undertook a task of resettlement of rural drinking water equipment superiors. Obviously, the detection of benzene exceeding the standard is only occasional. It's terrible that millions of people's drinking water safety should be suspended in the occasional fog barrier.

Tencent conducted a social survey. "Who do you think has not completely cured the source of water pollution in Lanzhou in 27 years?" Up to the time of writing here, 587 votes thought to be "Veolia Water", accounting for 4%; 11 418 votes thought to be "local authorities", accounting for 96%. I voted for the local authorities. It is not so much the "local authorities concerned" as the "decision makers of the local government", which throws away the drinking water safety of Lanzhou citizens, which is a serious livelihood of the people, and makes them fall into the occasional fog barrier.

Because of the physical characteristics of disposal equipment and the indispensable phenomena of ultra-pure water treatment equipment for people's livelihood, water, electricity and gas should be public goods, which should be provided by the government. Citizens pay taxes, which must include the purchase of water, electricity, gas and other government public effects. The Lanzhou Municipal Government, on the other hand, took water as a burden and sold it to foreign investors for 45% of their assets at an arrogant three-fold premium. Knowing that it is difficult for foreign businessmen to recover their capital in the past 30 years, how can foreign businessmen who take profit as their policy have other ways besides raising water prices to extort the masses and restraining investment and neglecting to maintain promotion? At that time, economists criticized Lanzhou severely for throwing away the burden of water affairs.

As a result, the source of water pollution in Lanzhou has not been completely cured for 27 years, and the previous local government has made many unforgivable mistakes. For example, we have agreed to build a large number of chemical enterprises near the drinking water source. We can't get rid of the illegal passage of pipelines in chemical enterprises through the drinking water self-flow ditch. PetroChina Lanhua Company has two serious leaks without tracing responsibility and cleaning treatment. The self-flow ditch has been in service for ten years and neglected severe maintenance, etc. Lanzhou Municipal Government said that the next step will be to constitute some of the water benzene exceeded the standard work of the relevant responsible units and responsible persons for further investigation and evidence collection. In fact, if the responsible persons of the previous government were selected in other places, or even in Bole, how could they conduct "investigation and evidence collection"? In fact, a higher level of discipline Commission is required to set up a special investigation team to thoroughly identify and trace responsibility.

What is more worrying is that Lanzhou is by no means alone in the situation of pollution of water sources for residents and pollution of water works and their pipelines. Lanzhou is not the first and hardly the last water pollution work. Drinking water safety, it is necessary to lead the country to attach great importance to the need for a thorough national investigation, and compulsory correction of risk removal. Drinking water detection frequency, the same need to adjust encryption, specifications need to be improved. But it can't be like Lanzhou. At one time, it takes 8 days to detect benzene. At the other time, it says that the content of benzene has reached the national standard. Together, the performance check of local governments should also include the level of public effectiveness of hydropower and electricity to alleviate the safety situation.
