May I ask why water quality testing work is necessary? Isn’t the Zailai we use in our daily life all directly applied? Then why is it still necessary to say that water quality testing should be done well? In fact, the reason is very simple!
The tap water we use daily is processed and tested by the water company to meet the standards before being delivered to every household. Only in this way can everyone use it with peace of mind. For drinking water, if it contains some harmful bacteria such as typhoid and cholera, it may cause various infectious diseases. If it is the water source for aquaculture, there are a large number of plankton in it, which reduces its oxygen content and thus causes a large number of fish deaths. If the fluoride content in water exceeds the standard, it can cause streaks on people’s teeth. In severe cases, it may even lead to “plaque disease” and severe ulcers. However, our drinking water mainly comes from underground or above ground, and the sources of these water sources cannot be guaranteed to be completely fine. So there is a transition period in the water supply company. Only when all the indicators of the water quality tested are qualified can it be delivered to every household.
The relevant departments must ensure the safety of water quality and cannot neglect the water quality testing process, as it directly affects people’s health. Therefore, it is essential to strictly supervise it. Only by ensuring that the water quality is qualified and delivered to various water supply networks can residents use it with peace of mind!
Of course, tap water testing is just one of the items. Why do we know that whether it is the sea, rivers or lakes, etc., they are all in motion. Once they are polluted, it will cause large-scale pollution. Therefore, we should also pay attention to some discharged sewage. Therefore, in addition to doing a good job in drinking water monitoring, there are also online monitoring of industrial wastewater, medical wastewater, domestic sewage, etc., which should not be ignored.
