Preface
In order to implement the Environmental Protection Law of the People's Republic of China and the Water Pollution Prevention and Control Law of the People's Republic of China, prevent and control water pollution, protect surface water quality, safeguard human health, and maintain a good ecosystem, this standard is formulated.
This standard divides standard items into: basic surface items, supplementary items for centralized drinking water sources, and specific items for centralized drinking water sources. The basic surface projects are applicable to surface water areas with use functions such as rivers, lakes, canals, canals, reservoirs, etc. throughout the country; The Puchong project and specific projects of centralized drinking water surface water sources are applicable to the first and second level protection areas of centralized drinking water surface water sources. The specific projects of centralized drinking water surface water sources shall be selected by the environmental protection administrative department of the people's government at or above the county level according to the characteristics of surface water quality and the needs of environmental management in the local area. The supplementary projects of centralized drinking water surface water sources and the selected specific projects shall serve as supplementary indicators for the basic projects.
This standard has a total of 109 items, including 24 basic surface items, 5 supplementary items for centralized drinking water sources, and 80 specific items for centralized drinking water sources.
Compared with GHZB1-1999, this standard has added a new indicator of total nitrogen in the basic surface items, deleted the basic requirements and three indicators of nitrite, non ionized ammonia, and Kjeldahl nitrogen, adjusted sulfate, chloride, nitrate, iron, and manganese as supplementary items for centralized drinking water sources, revised the standard values of seven items including pH, dissolved oxygen, ammonia nitrogen, total phosphorus, permanganate index, lead, and fecal coliforms, and added 40 specific items for centralized drinking water sources. This standard has removed specific project standard values for lakes and reservoirs.
The environmental protection administrative departments and relevant departments of the people's governments at or above the county level shall, according to their respective responsibilities, supervise and manage various types of surface water bodies in accordance with this standard.
The surface water estuary waters connected to the nearshore waters are managed according to the corresponding category standard values of this standard based on their water environmental functions, while the waters near the seawater functional zone are managed according to the corresponding category standard values of the "Seawater Quality Standards" based on their usage functions. The approved designated single fishery water area shall be managed in accordance with the Fisheries Water Quality Standards. The water quality of treated urban sewage and industrial wastewater with similar water quality to urban sewage used for agricultural irrigation shall be managed in accordance with the "Agricultural Irrigation Water Quality Standards".
The Ground (GB 383883) was published, with * revisions in 1988, the second revision in 1999, and the third revision this time. This standard shall come into effect on June 1, 2002, and both "Ground" (GB 3838-88) and "Surface" (GHZB1-1999) shall be abolished simultaneously.
This standard was proposed and managed by the National Science and Technology Standards Department.
This standard is revised by the Chinese Academy of Environmental Sciences.
This standard was approved by the state on April 26, 2002.
This standard is interpreted by the state *.

1 Scope
1.1 This standard classifies surface water environmental functions and protection objectives, specifies the items and limits that should be controlled for water environmental quality, as well as the implementation and supervision of water quality evaluation, analysis methods for water quality items, and standards.
1.2 This standard is applicable to surface water areas with use functions such as rivers, lakes, canals, canals, reservoirs, etc. within the territory of the People's Republic of China. Water bodies with specific functions shall comply with corresponding professional water quality standards.
2. Reference standards
The articles contained in the "Sanitary Standards for Drinking Water" (Ministry of Health, 2001) and the analytical method standards and specifications listed in Tables 4 to 6 of this standard, which are referenced in this standard, constitute the articles of this standard and have the same effect as this standard. When the above standards and specifications are revised, their versions should be used.
3 Water Function and Standard Classification
According to the environmental functions and protection objectives of surface water bodies, they are divided into five categories in order of their functions;
Class I is mainly applicable to source water and national nature reserves;
Class II is mainly applicable to first level protected areas of surface water sources for centralized drinking water, habitats of aquatic organisms, spawning grounds for fish and shrimp, and feeding grounds for juveniles and young fish;
Class III is mainly applicable to secondary protected areas of surface water sources for centralized domestic drinking water, wintering grounds for fish and shrimp, migration channels, aquaculture areas, and other fishery water bodies and swimming areas;
Class IV is mainly applicable to general industrial water use areas and recreational water use areas that are not in direct contact with the human body;
Class V is mainly applicable to agricultural water use areas and water bodies with general landscape requirements.
Corresponding to the five types of surface water functions mentioned above, the standard values of basic surface items are divided into five categories, and the corresponding standard values are implemented for each functional category. The standard value for high water functional categories is stricter than the standard value for low water functional categories. For the same water area with multiple functional categories, execute the standard value corresponding to the highest functional category. The implementation of water function and the achievement of functional category standards have the same meaning.
4 standard values
4.1 The standard limits for basic surface projects are shown in Table 1.
4.2 The standard limits for supplementary projects of centralized drinking water sources are shown in Table 2.
4.3 The specific project standard limits for centralized drinking water sources are shown in Table 3.
5. Water quality evaluation
5.1 The evaluation of surface water environmental quality should be based on the category of water functions that should be achieved, and the corresponding category standards should be selected for single factor evaluation. The evaluation results should indicate the compliance of water quality, and for those that exceed the standard, the exceeding items and exceeding multiples should be explained.
Water bodies with obvious characteristics during the wet, normal, and dry seasons should be evaluated for water quality according to different water periods.
The water quality evaluation of centralized drinking water sources should include the basic items in Table 1. The supplementary items in Table 2 and specific items selected and determined by the environmental protection administrative department of the people's government at or above the county level from Table 3.
6. Water quality monitoring
6.1 The project standard values specified in this standard require that the water sample settle naturally for 30 minutes after collection, and the upper non settling part be analyzed according to the prescribed method.
6.2 The sampling points and monitoring frequency for surface water quality monitoring should comply with the requirements of the national technical specifications for surface water environmental monitoring.
6.3 The analysis methods for water quality items in this standard should prioritize the methods specified in Tables 4-6, and other equivalent analysis methods such as ISO method system can also be used, but applicability testing must be conducted.
Implementation and supervision of 7 standards
7.1 This standard is supervised and implemented by the environmental protection administrative department and relevant departments of the people's government at or above the county level according to their respective responsibilities.
7.2 After purification treatment by the water treatment plant, the water quality of the centralized drinking water surface source project must meet the requirements of the "Sanitary Standards for Drinking Water".
7.3 The people's governments of provinces, autonomous regions, and municipalities directly under the Central Government may formulate local supplementary standards for items not specified in this standard and report them to the competent environmental protection administrative department for filing.
