 &Nbsp&Nbsp; The hygiene standards for drinking water are legal regulations on the various factors (physical, chemical, and biological) related to drinking water and human health, starting from protecting the physical health of the population and ensuring the quality of human life. They are also legal hygiene standards that are approved by relevant national departments and published in a certain form to achieve the prescribed values

Testing Requirements for Drinking Water

In order to ensure the hygiene and safety of drinking water and ensure human health, the country has formulated laws and regulations such as the "Law of the People's Republic of China on the Prevention and Control of Infectious Diseases", "Regulations on Urban Water Supply", "Measures for the Supervision and Management of Drinking Water Sanitation", "GB5749-2006 Drinking Water Sanitation Standard", and "GB8537-2008 Drinking Natural Mineral Water" to regulate centralized water supply Secondary water supply units (hereinafter referred to as water supply units) and products related to the hygiene and safety of drinking water shall undergo safety supervision

The detection range of domestic drinking water includes tap water, bottled water, direct drinking water, groundwater, and purified water
