1 GB X651 B Comparison of Microbial Items for Drinking Water Quality Standards between China and Some Other Countries WANG Zhong-we LI Zhe-min Dalian Environmental Monitoring Centre Dalian Liaoning China Abstract The differences in microbial items of drinking water quality standards were analyzed between sanitary standard for drinking water GB of China and foreign drinking water standards The drinking water standards and health advisories by United States Environmental Protection Agency Council Directive EC on the quality of water intended for human consumption by European Union guidelines for drinking-water quality and other countries quality standards for drinking water by World Health Organization. The standard characteristics of drinking water quality from China and other countries were comprehensively evaluated and some suggestion was made.
