Why should we pay attention to drinking water safety

When I was a child, I often had stomachache after drinking raw water. Adults would tell us that if I drank raw water, I would have bugs in my stomach. There are a lot of bacteria in raw water that we see you. Therefore, tap water can only be drunk when boiled, which is also a matter of common sense. (Pure Water Equipment Manufacturer)
When the industry was underdeveloped, there may only be bacterial contamination in tap water, but now no one dares to drink tap water directly. Groundwater pollution, water not only bacteria, but also heavy metals and other harmful substances pollution.
Professor Liu Wenjun and Professor Wang Zhansheng, experts in drinking water purification in China and the Environmental Research Institute of Tsinghua University, repeatedly emphasized the following five points on many different occasions:
1. The formulation of tap water standards should take into account the actual water quality in the vast areas of our country, which is the most basic safety line. For example, the tap water qualification standard is equivalent to 60 points in the examination, with only one passing line.
2. Some harmful substances, such as heavy metals, gradually accumulate. Even if a safe dose of harmful substances accumulates to a certain amount in the body, it can cause disease.
3. Residual chlorine in tap water always exists, because chlorine is intentionally added in the tap water process, and residual chlorine is not conducive to human health.
4. The 103 index of purified water cannot completely exhaust all kinds of metal elements that are harmful to human body, but are only common harmful substances. Therefore, even if all 103 indexes meet the standards, there is no guarantee that carcinogens beyond 103 indexes exist. (Pure Water Equipment Manufacturer)
5. Tap water safety standard is based on statistical data and is the basic guarantee line of safety. In real life, due to the difference of personal physique, everyone has different tolerance for harmful substances. For people whose tolerance is lower than the average level, the safety content of most people may be dangerous for him.
