Recently, there is a popular science news about the difference between mineral water, mineral water, and purified water that has received extensive attention on the Weibo platform. Weibo content is: “Pure water and mineral water are all actually 'artificial water'. Because it is cheaper, the pure water in the packaged drinking water market accounts for the majority, which is the world of Wahaha and Cestbon, but with the change of people's health concept, mineral water will become the mainstream of the market.Industry sources claim that a bottle of mineral water costs 50% to 60%. For packaging, 4% for transportation, profitability is considerable."
As we all know, water is the source of life. The quality of drinking water is closely related to people's health. Most of the family’s standing drinking water is still boiled boiled water. Whether or not the tap water used at home is truly "standard" has always been a concern in people's hearts. However, in recent years, there have been frequent reports of water pollution, and it has been difficult for people to hang up.
Before the implementation of the new national standard for water supply in 2012, some reporters had visited the Taiyuan Water Supply Company. In Taiyuan, for example, Shi Xiaodong, director of the water quality department of the city’s water company, introduced the tap water production process in detail. All the tap water in Taiyuan was passed through water, water plants, and transmission and distribution network, and then passed the national requirements. After all the 106 indicators have passed the test, they will eventually flow to thousands of households. The article also mentioned a water quality testing instrument worth more than 1.5 million yuan.
Is it really “qualified†that the new national standard of tap water implements a tap water that flows out after inspection of these layers of precision high-end equipment? According to media statistics, from January to March 2014, there were 10 incidents of tap water odors reported by media across the country, which were distributed in multiple cities. The more weird than the tap water smell is, of these 10 incidents of tap water odors, there are actually 6 cases where “quality of water testing is up to standardâ€, and only 2 sources have been clearly identified.
The new national standard for drinking water is a mandatory standard. It has been implemented since 2007. Non-compliance drinking water production enterprises will be stopped and punished by administrative law enforcement agencies. Due to the lack of detection capability, the standard set up a five-year transition period, and all indicators are scheduled to be implemented on July 1, 2012. Now that the deadline has passed, the Ministry of Health has given another timetable: By 2015, all provinces (autonomous regions, municipalities directly under the Central Government) and provincial capitals will be able to implement full coverage of 106 indicators.
The Ministry of Housing and Urban-Rural Development has water quality monitoring centers in more than 40 cities across the country, of which more than 20 have full-indicator detection capabilities and detection capabilities are stronger than the health system. However, the health system considers itself as a third-party monitoring agency. The water quality monitoring center and the water plant of the residential construction system are “one family†and belong to “industry†supervision. However, due to the lack of funds in the health sector, the testing system could not be completed.
The market potential of third-party water quality testing bodies is huge With the media constantly calling for third-party testing agencies to intervene in urban water supply monitoring, the tender information for third-party testing of urban water supply starts to appear frequently. Many cities including Wenzhou, Shanghai, Guangzhou, Shenzhen, and Yinchuan have issued invitations to tender for urban water supply.
It is expected that in the next one to two years, the national third-party testing of urban water supply will generate huge market demand. Water quality monitoring in water sources, sewage and sewage treatment, water plant production monitoring, secondary water supply pipe network monitoring, upgrading of pipe network materials, and secondary water storage equipment will generate a large number of testing needs. Sudden outbreaks of third-party testing requirements will become a stable third-party testing market after sustained high growth. According to relevant website analysis and prediction, the potential of the national market for water supply testing in cities will reach 10 billion yuan/year.
Such a huge market potential will surely attract influxes of capital from all walks of life. While attracting market attention, it also reminds the market that how to make better use of third-party testing to truly improve the quality of existing tap water is just a matter of public The key to benefiting people is the key to fiscal spending. As an ordinary consumer, we only hope that the relevant government can devote sufficient efforts to the management of water quality safety so that everyone can enjoy a safe water.
Tips Then, in the absence of professional testing methods, how can ordinary citizens determine whether tap water in their home can be safely consumed? Xiao Bian has collected six relatively simple methods for your reference:
Look: Use a glass with high transparency to be filled with a glass of water, and look at the light for fine substances suspended in water; stand for three hours, and then observe whether there is sediment at the bottom of the cup. If so, indicate that the suspended impurities in the water have exceeded the standard .
Wen: Use a glass to get a glass of water from the faucet as far away as possible, and then smell it with your nose. Is there a smell of bleach (chlorine)? If the smell of bleach (chlorine) can be smelled, the residual chlorine in the tap water is excessive.
Taste: Drink hot boiled water, with or without bleach (chlorine). If you can smell the bleach (chlorine), it means that there is excess chlorine in your tap water.
View: Tea with tap water, after the night to observe whether the black tea? If the tea turns black, it shows that the iron and manganese in the tap water are exceeding the standard.
Products: taste boiled water, to see whether the taste of astringent? If yes, the hardness of the water is too high. Use relevant facilities for softening.
Check: Check the water heater and kettle in the house. Is there a layer of yellow dirt on the inner wall? If so, it also indicates that the hardness of the water is too high (the content of calcium and magnesium salts is too high).
