defense after the fall of Lanzhou Water Safety
Lanzhou local water benzene poisoning cases occurred, once again sounded the alarm for the safety of urban water supply
text / "Outlook" Newsweek reporter Zhang Qin
4 17, is the seventh day of Lanzhou benzene exceeded local tap water after the event. Although as early as three days before, had been lifted Lanzhou emergency measures to fully restore the water supply, but the public Zhouhuai Jun morning drink the first cup of water is still a lot of hoarding mineral water down a few days ago.
citizens in order to dispel the doubts, the local government is contaminated lots of alternative emergency pipeline laying prevent new danger, and environmental protection, disease control departments are still in a frequency of detection of water a day benzene content, and to inform the public. 17 released data show that water plant outlet and the main city tap water was not detected in four districts of the benzene content.
However, many people still haunt Maryland. Especially in the most affected, water plant location Xigu District, there are Cheap Manchester United Jerseys still some people three meals a day is pure boiled noodles, frozen dumplings and other "water-saving recipes."
from the current investigation, the cause of the incident seems to be rather "accidental" - a blasting accident 27 years ago, the legacy of 60 years of oil eroded cement retention ditch. But even more worth pondering, it is "accidental" behind the "inevitable."
Why risk contamination of water companies will be created in the vicinity? Why 27 years ago, the oil still exist? Why Water from the confirmation of benzene exceeded the reporting, experienced 14 hours? For this incident may involve millions of people's lives and health, the government announced from sped why spend 11 hours? ......
Obviously, industrial city of Lanzhou Northwest public events from this, once again sounded the alarm for the safety of urban water supply.
opinion focused five Focus
current, Lanzhou, "said city water" opinion is focused on five major focus.
Focus One: Discovering the former benzene exceeded, the water is safe? Prior to the masses is already a lot of drinking water exceeded the benzene?
DirectorLanzhou City Water Corporation Water Quality Monitoring Center, National Water Quality Monitoring Network, Lanzhou City station owners Tin Hung told "Outlook" Newsweek reporter, indicators of water quality testing in 106 countries with new regulations, the benzene content of non-conventional test items. But they are conducted in a March test, and therefore the water is safe before March. But so far, Lanzhou departments, waterworks were not for the masses before April 11 whether benzene excessive drinking tap water to make a positive response.
Focus II: water benzene exceeded whether early March Lanzhou tap water smell about?
Deputy General ManagerLanzhou Veolia Water (Group) Company, said Yan Xiaotao, March tap water smell after melting snow into the upper reaches of the Yellow River in the decaying substance-induced, was based on feedback from the community for testing, the results showed that 106 indicators all qualified.
Focus III: first discovered benzene exceeded what time? Hysteresis announced the existence of the problem?
Yan Xiaotao said on April 2, Veolia water quality sampling, found during the analysis on the 10th of abnormal levels of benzene, followed by a test again, at 15:00 on the 10th to confirm benzene exceeded 11 am 5:00 reported Lanzhou municipal government, there is no problem delaying concealed.
But it is worth noting that, from at 3:00 on the 11th, Veolia company began adding activated carbon to the sedimentation tank, trying to degradation of benzene contamination of water bodies, the two-hour time difference with the official reporting exists.
and Lanzhou timetable announced show that from at 5:00 on Cheap Lazio Jerseys the 11th arrived at the 16:30 news conference, experienced Lanzhou scene to dispose of the main person responsible for the establishment of emergency response teams, multi-sectoral retest samples Gansu Province, set up emergency steering group, to convey the spirit and once again deployed superiors, writing press releases and other multiple links, spent more than 11 hours.
Some scholars believe that the correct approach is to take urgent and decisive measures to drastically reduced deployment, meeting time, early emergency actions to inform the public.
Focus Four: gravity erosion ditch oil come from? Who will bear the responsibility for the pollution? Whether contaminated artesian ditch "extended"?
preliminary investigation, the local tap water benzene poisoning cases should ditch surrounding the oil gravity caused. Lanzhou Petrochemical oil from the last century, 80 years after the original Portland accident happened physically penetrate into underground blasting residue, but further demonstration and analysis. Lanzhou benzene exceeded local water emergency leading group said that after identifying the reasons, will be severely punished. The ditch was contaminated gravity of cement in 1955, building aqueducts, the design life of 50 Cheap Wolfsburg Jerseys years, the actual use has been nearly 60 years.
Focus Five: water plant if there is lack of supervision? Why is the existence of "South Orange North trifoliate" phenomenon after international water giant Veolia holdings Maryland?
Lanzhou benzene poisoning cases local water emergency leading group on the 15th, said the problem of water supply regulation is not in place after the joint enterprise does exist, but also exposed some weaknesses on urban management, Lanzhou City will learn a lesson, to strengthen supervision to prevent similar incidents from happening again.
security perimeter has been repeatedly breakthrough
current survey, polluting oil from at 8:50 on December 28, 1987, the physical original Portland (now PetroChina Lanzhou Petrochemical Company) crude distillation plant raw power plant blasting accident occurred. At that time, about 90 cubic meters of residue leaked, including 34 tons of residue material failed to run recovery, seep into the ground below.
However, not all uncover the mystery.
First, after the oil into the ground, who are going to sound processing? Cheap Stuttgart Jerseys In this regard, Environmental Engineering Research Institute, Lanzhou University ZHANG Ming-quan, told reporters that China's relevant environmental regulations already established the principle of "polluter pays processing" after the original enterprises have been merged, it becomes correspondingly "Who receivership, who handles. "
then, and the enterprises have failed to fulfill this responsibility in the end it? Unfortunately, when the correspondents on this issue trying to contact a telephone interview PetroChina Lanzhou Petrochemical Company, the relevant person in charge and the Director of the Office, or just do not answer the phone, or else the reporter identified himself after hanging up the phone.
Secondly, in accordance with the provisions of the Water landlords cities and megacities aqueduct surrounding 50 meters is a class of water source protection areas, does not allow any building has nothing to do with the presence of water facilities, in the event that may affect the safety of drinking water pollutants is to be promptly removed.
So, Cheap Red Bull Jerseys Lanzhou municipal environmental protection departments have tracked over the years to deal with it? In this regard, Lanzhou Municipal Environmental Protection Bureau Jiang Yan child without making a positive response in an interview with our reporter in a telephone interview.
ZHANG Ming-quan Speaking of oil pollution treatment technology is not difficult. Even in the 1980s, using the technology and economic conditions, as well as soil and groundwater contamination were carried off indigenous (ie for soil) and swap groundwater treatment and disposal.
"If we say that was due to lack of environmental awareness, but so far it is difficult to understand the delay." he said.
step back, even if these links have emerged flaws, there are also the last line of defense: early warning and monitoring water quality. However, this is also not withstood the test of defense.
Lanzhou Veolia according to the company's statement, the discovery of water benzene exceeded "fortuitous." Because the water content of benzene routine testing of water quality monitoring 106 index did not belong to the state. However, as the company undertook a county in Gansu tap water testing throughout the project, the way to detect water Lanzhou, only found in tap water in advance excessive levels of benzene.
to this explanation, ZHANG Ming-quan water areas considered to be misinterpreted the relevant provisions of the State.
he spoke, 106 national indicators of water quality testing is indeed a considerable part of the non-conventional indicators of test items, once or twice a year can be detected. But there is an important prerequisite: water source environment is safe. While in the presence of water sources and water plant pollution or threat of pollution, water plants have a responsibility to monitor encrypted frequency, increase monitoring efforts to prevent accidents.
reality is that the West Lanzhou Veolia solid chemical companies located in densely industrial area, surrounded by oil spills have occurred repeatedly environmental pollution accident, so he believes that companies are still orderly conduct water quality testing is justified.
Howno longer fall
never too late.
in urban water supply security perimeter overall design, ZHANG Ming-quan think, should further clarify the welfare of urban water supply security attributes, clear government and business investment in their responsibility to further crack the problem of insufficient public investment.
in the governance of water pollution, Civil and Economic Law, Gansu Political Science and Law, Associate Dean Guo Wu believes that China's Water Pollution Control Act, Solid Waste Pollution Prevention Law and the Water Law are on the disposal of oil pollution of drinking water made provisions, but because the relevant legal provisions scattered, only partially reflected in the way outlined in the terms and provisions of more general principle, therefore, in practice there is often poor operability drawbacks. Meanwhile, low-cost corporate law, laws and regulations relating to environmental pollution polluting enterprises in the maximum amount of the administrative penalty not exceeding $ 500,000.
He said that it is necessary to improve the treatment and disposal of oil pollution related administrative regulations, departmental rules or procedural norms, while strengthening environmental protection and other regulatory responsibilities and power sectors, and by amending the relevant laws and regulations, environmental law enforcement and try environmental litigation relative access mechanisms to improve the cost of illegal oil pollution enterprises.
warning monitoring water quality, experts say, urging water plant in strict accordance with specifications to strengthen early warning and monitoring of water quality, depending on the circumstances of the encryption monitoring frequency should also establish an independent water plant water quality indicators in monitoring third party.
open a second water supply security is also an important part of the defense. Reporters learned that, in 2013, Lanzhou, preliminary work has been started from the second water diversion liujiaxia reservoir construction projects. Lanzhou benzene exceeded local water emergency leading group spokesman, said Wang Ning, Maryland will start construction as soon as possible to create conditions to solve the problem of urban water security for all.
Some experts believe that in this industrial city like Lanzhou city water to ensure safety, but also to gradually break the layout of the city is unreasonable and other issues. Statistics show that in the 1950s, after the former Soviet Union and our experts repeated comparison, Maryland selected the tap water intake is located upstream of the Yellow River in West Xigu XIAOLIUGOU area. According to an insider, was here as a water source protection areas surrounding non-industrial enterprises, no outfall, water is no problem. However, the passage of time, this place has now the Lanzhou Chemical Industrial Zone enterprise clouds. According to incomplete statistics, only the upstream and the surrounding water intake on the distribution of chemical and other industrial enterprises more than 30.
Panel membersnational environmental emergency, Water Research Institute Beijing Normal University professor Wang Jinsheng think, and the Yellow River in Lanzhou Petrochemical contradiction between water sources caused by historical reasons, chemical companies should not have to layout and water together, Because the two mutually contradictory body. Today, one of the people most concerned about the topic of Lanzhou, Lanzhou Petrochemical is when the oil out of the city park.
