Water Quality Standard for Drinking Water Sources
CJ 3020-93

1 thematic content and scope of application
The standards for the quality of life indicators of drinking water sources, water quality grading, standards limits, water quality testing and monitoring the implementation of the standards.
This standard applies to focus on urban and rural life-style of drinking water and water (including the various units-owned drinking water sources of water). Distributed the quality of life of drinking water sources, reference should also be used.

2 cited standards
GB5749 drinking water health standards

GB11729 source water health standards Chlorothalonil
GB5750 drinking water standards test

3 life drinking water source quality classification
Life is divided into two drinking water, the polarization of the standard limit in table 1.

3.1 a water source: good water quality. Just disinfection of groundwater, surface water on summary purification treatment (such as filters), after disinfection for drinking to life.
3.2 secondary water source: the mild water pollution. The conventional purification treatment (such as flocculation, sedimentation, filtration and disinfection, etc.), the water quality to meet GB5749, for life to drink.
3.3 water quality standards limit the concentration of more than two sources of water, not as drinking water sources of water. If the conditions required to be used, should be used accordingly purification process for processing. After dealing with the water quality should meet GB5749, and a provincial, municipal, regional health department (bureau) and the competent authority.

4 standard limits
4.1 the quality of life of drinking water sources should not exceed a table under the limit.
4.2 water sources such as water containing not included in Table 1 of the harmful substances, should be the relevant regulations.

5 water quality test
5.1 water quality tests on the implementation of GB5750. Beryllium tests on the implementation of GB8161. Chlorothalonil tests on the implementation of GB1729.
According to a 5.2 shall not be instantaneous detection of the use of this standard.
5.3 has chosen to use the water or water, at least once every quarter for the entire sample analysis test.

6 oversee the implementation of standards
6.1 standard from urban and rural planning, design and drinking water supply, and other relevant units responsible for the implementation. Drinking water supply unit in charge of departments, health departments are responsible for supervision and inspection of the implementation.
6.2 at all levels of public security, planning, health, environmental protection, water conservancy and the shipping sector should combine their respective responsibilities, coordination unit to supply water for Health Protection District of protection.
