With the development of economy and the increase of population, water resources in many areas begin to be short, and the drinking water source in some cities is particularly polluted, and the safety of drinking water for residents is threatened to a certain extent. In 1985, the “drinking water sanitation Standard” (GB5749-85) can no longer guarantee the health needs. So what should we do? This chapter and water quality monitoring instrument manufacturers to understand drinking water quality monitoring standards with you.
It is understood that the Ministry of Health and China’s standardization management department have made certain amendments to the previous standards, and issued a new new standard “Drinking water sanitation standard” (GB5749-2006). On July 1, 2007, this standard was issued by China’s Standards Committee and the Ministry of Health, and the mandatory national standard and 13 Chinese standards for drinking water sanitation inspection were formally implemented.

2.Harmonization of sanitary standards for drinking water in urban and rural areas;
3.To achieve international standards for drinking water, the selection of new standard water quality items and index values takes full account of the actual situation, and refers to the World Health Organization’s “Drinking Water Quality Standards”, referring to a number of international drinking water standards.
