When it comes to water quality monitoring in spring, we still need to be alert to 5 major issues

my country’s water quality monitoring started later than developed countries, and there are still some problems, which can be summarized as follows The following aspects:

　(1) Lack of targeted water quality testing standards

At present, our country implements unified water quality testing standards and has not yet implemented unified water quality testing standards. Taking into account the differences in different regions and water bodies. Taking drinking water as an example, for areas with serious pollution and complex water source conditions, even if the water quality is fully analyzed, there may still be situations where some pollutants have not been removed, and some more targeted refinements are needed. The indicators are then measured; for areas with good water source quality, comprehensive analysis is a waste of monitoring resources.

　(2) Monitoring costs are high and difficult to promote comprehensively

Most of the instruments used for water quality testing are precision instruments, which are expensive to build and the subsequent maintenance costs are also huge. The expenditure is not small, so only some large water quality monitoring centers have the ability to equip all the instruments. The monitoring capabilities of some small and medium-sized cities and rural areas are also limited as a result. This has, to a certain extent, led to uneven distribution of water quality monitoring centers across the country and differences in monitoring levels.

　(3) The level of third-party testing agencies is uneven and difficult to manage in a unified manner

　In order to promote the transfer of national surface water environmental quality monitoring powers, Since October 2017, the country has fully launched the surface water collection, measurement and separation work. A third-party monitoring agency is responsible for the sampling work, and the water samples are encrypted and sent to the monitoring and analysis center. Although this approach has improved the reliability of water quality information to a certain extent, due to the different levels of third-party agencies, irregularities in actual operations will lead to inaccurate water quality information. in addition, since the competent authorities currently mainly select third-party testing institutions through bidding, low-price competition has also followed, which has affected the quality of water quality testing work to a certain extent and had a negative impact on water quality data.

　(4) Over-reliance on imports of precision equipment

Most of the instruments used for water quality monitoring are precision instruments and equipment. my country is a relatively developed country in the manufacturing of precision instruments and equipment. There is still a certain gap. Although the localization of testing instruments has made great progress, precision equipment still mainly relies on imports, resulting in high testing costs.

　(5) Lack of professional talents

　With the continuous improvement of water quality monitoring technology, the requirements for the professional quality of operators have also increased. In particular, technicians responsible for tap water quality monitoring must not only be proficient in operating instruments, but also have the ability to predict and respond in advance based on changes in various water quality indices. Due to the late start of water quality monitoring in my country, the scale of technical personnel is limited and their professionalism is lacking.
