Hello dear, happy to answer your <>

The following are the top 10 water quality testing authorities in China:1Institute of Water Environment, Institute of Water Environment, Chinese Academy of Environmental Sciences, 2

China Environmental Monitoring Station 3Institute of Hydrobiology, Chinese Academy of Sciences 4Chinese Society of Environmental Sciences 5

Chinese Society of Water Engineering 6Institute of Hydrogeology and Environmental Geology, China Geological Survey7China Institute of Water Resources and Hydropower Research 8

Department of Water Environment Management, Ministry of Environmental Protection, 9Local testing institutions under the Ministry of Environmental Protection of China10The Hydrological Monitoring Center of the China Lula Hydrology and Water Resources Bureau is an authoritative water quality testing institution in China, with high professional capabilities and influence in water quality testing, monitoring, restoration and management.

If you want to test the water quality, you can go to the Product Quality Supervision and Inspection Institute and the Health Bureau, which can be used for water quality testing. In addition, you can also find local water companies and water testing centers, which can also conduct water quality testing. Because the addresses of these departments are different in each place, if you want to find them, you can ask the local personnel for specific addresses, and then find the corresponding departments to help us conduct water quality testing.

The scope of water quality testing includes sewage, seawater, farmland irrigation water, landscape water, mineral water, cooling water, groundwater, industrial water, fishery water, domestic water, pure water, swimming pool water, test water, etc.

When testing water quality, the color, turbidity, visible substances, chemical oxygen demand, total number of bacteria, odor and taste, residual chlorine, total coliform bacteria, heat-resistant coliform bacteria and other indicators of the water source are mainly checked.

If you feel that there is a problem with the water quality at home, you can check it by looking, smelling, tasting, watching, shouting congratulatory products, and checking the remaining dishes, for example, making tea with tap water, if the tea turns black overnight, it means that the iron and manganese in the tap water are seriously exceeded, and you need to use a water purifier to treat it.

Failure to test water quality is harmful to the human body.

1. If the quality of drinking water we live in is not up to standard, it will contain a lot of pathogenic organisms, and drinking this water at this time is likely to bring us a lot of diseases.

2. If the quality of the drinking water is relatively hard and the water quality is relatively poor, it may also lead to other symptoms such as colic after drinking.

3. If the drinking water is found to be unqualified during the test, it is very likely that some radioactive substances will be released, which are harmful to the human body. <>

The local monitoring stations under the national water quality monitoring, the local environmental protection bureaus under the State Environmental Protection Tanyuan Bureau, the local epidemic prevention departments, and the local food safety supervision agencies, all of which are not national statutory testing institutions.

Water quality testing. For the inspection of water quality, it can be divided into scientific system inspection and daily monitoring.

The simplest thing in daily monitoring is to boil the water to see how much scale there is, so that you can check the content of compounds such as calcium and magnesium in the raw water, how much the content of this compound can affect the quality of the water.

Testing scope: sewage, pure water, seawater, fishery water, swimming pool water, reclaimed water, bottled pure water, drinking natural mineral water, cooling water, farmland irrigation water, landscape water, drinking water, groundwater, boiler water, surface water, industrial water, test water, etc.

Purpose: Drinking water mainly considers the impact on human health, and its water quality standards include physical and chemical indicators, as well as microbial indicators. For industrial water, consider whether it will affect the quality of the product or be satisfied that it will damage the containers and pipelines. <>

Legal analysis: the local monitoring stations under the national water quality monitoring, the local environmental protection bureaus under the State Environmental Protection Bureau, the local epidemic prevention departments, and the local food safety supervision agencies, all of which are national statutory testing institutions.

Legal basis: Law of the People's Republic of China on the Prevention and Control of Water Pollution

Article 1: This Law is enacted so as to prevent and control water pollution, protect and improve the environment, ensure the safety of drinking water, and promote comprehensive, coordinated and sustainable economic and social development.

Article 3: The prevention and control of water pollution shall adhere to the principles of putting prevention first, combining prevention and control, and comprehensive treatment, giving priority to the protection of drinking water sources, strictly controlling industrial pollution and urban life pollution, preventing and controlling agricultural non-point source pollution, actively advancing the construction of ecological governance projects, and preventing, controlling, and reducing water environmental pollution and ecological damage.

The water quality testing center can monitor the water quality of drinking water sources.

Because there are many items that need to be measured according to different projects, and the standards for monitoring fees vary from place to place, it is still necessary to go to the local monitoring station or epidemic prevention station to find out.

Water quality monitoring is the process of monitoring and measuring the types of pollutants in the water body, the concentration and change trend of various pollutants, and evaluating the water quality status. The monitoring covers a wide range of unpolluted and contaminated natural water (rivers, rivers, lakes, seas and groundwater) and a wide range of industrial drainage.

The main monitoring items can be divided into two categories: one is a comprehensive index reflecting the water quality status, such as temperature, color, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand; The other category is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury and organic pesticides. In order to objectively evaluate the water quality of rivers and oceans, in addition to the above-mentioned monitoring items, it is sometimes necessary to measure the flow rate and flow rate.

The scope includes sewage, pure water, seawater, fishery water, swimming pool water, reclaimed water, bottled pure water, drinking natural mineral water, cooling water, farmland irrigation water, landscape water, domestic drinking water, groundwater, boiler water, surface water, industrial water, test water, etc.

Water quality testing indicators:

1. Chromaticity: Most people can detect the color of drinking water when it is greater than 15 degrees, and people feel disgusted when it is greater than 30 degrees. The standard stipulates that the color of drinking water should not exceed 15 degrees.

2. Turbidity: It is an expression of the optical properties of water samples, which is used to indicate the degree of clarity and turbidity of water, which is one of the most important indicators to measure the good degree of water quality, and is also an important basis for assessing the purification efficiency of water treatment equipment and evaluating the status of water treatment technology.

The reduction of turbidity means that the content of organic matter, bacteria, viruses and other microorganisms in the water body is reduced, which can not only improve the disinfection and sterilization effect, but also help reduce the amount of halogenated organic matter.

3. Odor and taste: The production of water odor is mainly the presence of organic matter, which may be caused by the manifestation of increased biological activity or industrial pollution. A change in the normal odor of a public water supply can be a sign of a change in the quality of the raw water or inadequate water treatment.

4. Visible to the naked eye: mainly refers to particles or other suspended substances existing in water that can be observed with the naked eye.

5. Residual chlorine: Residual chlorine refers to the amount of chlorine remaining in the water after chlorination and disinfection. It has a continuous sterilization ability in the water to prevent the self-contamination of the water supply pipeline and ensure the quality of the water supply.

6. Chemical oxygen demand: refers to the oxygen required by chemical oxidants to oxidize organic pollutants in water. The higher the chemical oxygen demand, the more organic pollutants there are in the water.

Organic pollutants in water are mainly produced by the discharge of domestic sewage or industrial wastewater, and the decomposition of animals and plants.

7. Total number of bacteria: The bacteria contained in the water, ** in the air, soil, sewage, garbage and the corpses of animals and plants, the types of bacteria in the water are diverse, including pathogenic bacteria. In China, the standard for drinking water is that the total number of bacteria in 1ml of water does not exceed 100.

8. Total coliform bacteria: It is an indicator of fecal contamination, and the situation detected from it can indicate whether there is fecal contamination in the water and its degree of pollution. In the process of water purification, if the total coliform index can meet the requirements of drinking water standards after disinfection, it means that other pathogens and protobacteria have also been basically killed.

The standard is no more than 3 L's in the test.

9. Heat-resistant coliform bacteria: It more appropriately reflects the degree of food contamination by human and animal feces than coliform bacteria, and is also an indicator bacteria of fecal pollution in water bodies.

If it comes to BAI to carcinogenic litigation issues, DU

You can contact the local CDC for water quality testing, and the CDC will be better able to coordinate as a first-class department. Although the CMA qualification of a third-party organization (such as Guangdong Huake Testing) issued a CMA report is also legally effective, the testing ** does not include the labor cost of litigation, the profit is meager, if the need for a third-party testing agency to participate in the court testimony, the testing agency will lose money, so generally do not accept litigation service orders, only accept regular orders.

Technical supervision.

Water quality testing can be provided by the product quality supervision and testing institute under the bureau BAI, the health supervision institute under the health bureau or the water quality testing of the DAO water supply company.

Water is the source of life and plays a pivotal role in social and economic development, and water quality testing is one of the important means to ensure water quality safety. The quality of drinking water should meet the following basic requirements to ensure the safety of users:

1. Drinking water shall not contain pathogenic microorganisms.

2. The chemical substances in drinking water shall not endanger human health.

3. Radioactive substances in drinking water shall not endanger human health.

4. The sensory properties of drinking water are good.

5. Drinking water should be disinfected.

Product quality supervision and testing institute under the Technical Supervision and Restoration Bureau, or health supervision institute under the Health Bureau; The water quality testing center of the city water supply company can provide water quality testing!

On this basis, you can find a higher level of product quality inspection or health supervision in the provincial capital, the higher the city's level, the more authoritative.

The environmental protection department is also more reliable for this inspection, but it is still lower than the above two departments in terms of authority.

If you want a more accurate and fast test, you can go to the testing institutes of some water conservancy universities, which are also more authoritative.

Environmental testing (EIA) is the use of modern scientific and technological means to monitor, monitor and measure various environmental elements (environmental pollutants) that represent environmental pollution and environmental quality. As a professional environmental testing organization, Inger can provide environmental testing services including water quality testing, air testing, soil testing, solid waste testing, biological testing, noise and vibration testing, electromagnetic radiation testing, radioactive testing, thermal testing, light testing, health (pathogens, viruses, parasites, etc.) testing and other items according to various standards, and issue test reports.

A third-party testing agency with CMA CNAS qualification can compare the scale of the laboratory and the holding of various qualifications, and choose the most authoritative one.

Henan Water Quality Testing, Zhengzhou Water Quality Testing, Zhengzhou Zhongjian Building Yuanyan Engineering Testing Company, impartially, accurately, and quickly issued CMA test reports.

We generally send a third party for testing, and of course the third party must be authoritative. The test results and the report must be recognized by the state, and we send CTI technical testing, which can be referenced.
