Hazard 1: it is difficult to trace the water source and ensure the water quality. Some bottled water is said to be natural mineral water, but after investigation, it is found that the water source is all garbage; Some said it was mineral water, but it turned out to be tap water and so on. The source of bottled water is constantly problematic, and the water quality is difficult to guarantee.
Hazard 2: Irregular disinfection of drinking fountains will breed bacteria and viruses. On weekdays, when we change bottled water, we can see bubbles coming out. At this time, most of the bacteria in the air are dissolved in the water and multiply rapidly in the water. Three days after Kaifeng, the bacteria exceeded the standard by 227 times, more than tap water bacteria!
Hazard 3: Inferior barrels may contain carcinogens. General bottled water is made of PC and TPE. PC barrel is a so-called good barrel, but this can only be said relatively, but it will also produce chemicals, such as bisphenol A, which has good transparency and high rigidity, so the barrel wall is not very thick and colorless and transparent. The TPE bucket is relatively poor. It is usually used for bottled water at one time. Repeated use is toxic and banned in many areas.
Hazard 4: Overtime service buckets become a "paradise" for bacteria. Some small and medium-sized bottled water producers do not seriously disinfect the recycled empty barrels, but simply rinse them with tap water before using them, resulting in a large number of bacteria in the barrels. With this bottled water, even the best water must be polluted. Some buckets that have been out of service have become a "paradise" for bacteria.
Hazard 5: Black-hearted water and black-hearted bucket: harmful to health. "Black-hearted water" refers to illegal vendors directly filling bottled water with tap water. The polymer in the industrial waste of "black-hearted barrel" will seep out in the water environment, which is an organic pollutant and easy to cause cancer to human body. People who drink "black-hearted bucket" water will not feel it immediately, but like chronic poisoning, the harm will take many years to appear.
