Note： a、Primary water source: good water quality, groundwater only needs to be disinfected, while surface water can be purified and disinfected for daily consumption. b、Secondary water source: the water quality is slightly polluted, regular purification treatment (such as coagulation, sedimentation, filtration, disinfection, etc.) can produce water quality that meets the requirements of GB5749 and is suitable for daily drinking. c、Water sources with a concentration exceeding the second level standard limit should not be used as sources of drinking water for daily life. If conditions require utilization, corresponding purification processes should be used for treatment. The treated water quality should comply with GB5749 regulations and obtain approval from provincial, municipal, and autonomous region health departments (bureaus) and competent authorities.
