Investigation report on drinking water

Investigation report on drinking water

In today's society, reports are very important, and writing reports should avoid being too long. I believe many friends are very upset about writing reports. The following is the drinking water research report I collected for your reference, hoping to help friends in need.

Drinking water research report 1 Water is the source of life, and drinking water is the basic demand of human survival. The safety of drinking water is directly related to the life, health and quality of life of the broad masses of people. Recently, according to the monitoring results of the county CDC on the water quality of rural safe drinking water project in this county in recent three years, this paper analyzes the current situation of rural drinking water quality safety in our county and the causes of water quality changes, and puts forward corresponding prevention and control countermeasures and suggestions, so as to provide reference for further strengthening the management of rural drinking water safety.

First, the county drinking water quality status

Our county is located in Qinba Mountain area, with abundant rainfall, with an average annual rainfall of 798mm. There are more than 760 large and small rivers in the territory, and the Hanjiang River is 47km in the territory, which is rich in water resources. Since 20xx, the county has invested more than 80 million yuan to build 180 single rural safe drinking water projects and 14 large market town water supply projects. At present, the daily monitoring of urban water supply is carried out by the laboratory of county water supply company, and regular sampling is sent to the municipal CDC for testing. County CDC undertakes the national "Water Quality and Hygiene Monitoring Project of Rural Safe Drinking Water Project", and the monitoring data is directly reported to the National Center for Disease Control and Prevention through the private network.

In recent three years, the county CDC has investigated and sampled 20 rural centralized safe drinking water projects in two towns of the county1according to the Hygienic Standard for Drinking Water (GB5749-20xx), and conducted microbial, toxicological and sensory monitoring in dry season (March-April) and wet season (July-August) every year. The monitoring results for three consecutive years showed that 70%-75% of the drinking water projects in the county were found to have exceeded the total coliforms and heat-resistant coliforms, while the free chlorine was basically zero. In addition, other monitoring indicators did not exceed the standard, indicating that the water quality of the drinking water source itself is good. Among them, the PH value varies with the seasons. In dry season, the PH value is mostly acidic, ranging from 7.2 to 7.5, and in rainy season, it is mostly alkaline, ranging from 7.8 to 8.2. The total hardness of water quality is between 70 and 280 mg/L, and 80% of monitoring points are less than 200mg/L, with no seasonal change, and the total hardness is far below the national drinking water index and limit. Toxicological indicators, general chemical indicators and other monitoring indicators are stable within the national drinking water indicators and limits, and there are no natural toxic and harmful substances and industrial pollution.

Second, the main factors leading to excessive water quality

Judging from the above test results, the rural drinking water quality in this county exceeds the standard because of microorganisms, and the factors leading to this situation are:

1. Contaminated by microbial pollution sources. The main sources of pollution include two aspects: first, domestic pollution. The water sources of centralized water supply in the county are surface ditches and streams, which are collected from the vast rain-collecting areas. At present, the rural infrastructure in our county is still relatively backward. In many towns and villages, domestic garbage is piled up in the open air and domestic sewage is discharged at will. Sewage such as kitchen cooking water, bath water and toilet flushing water flows into streams and rivers with the erosion of surface rain, especially the drainage pipes of some farmers' homes directly lead to ditches and rivers for sewage discharge. The second is the pollution of livestock and poultry breeding. The existing rural breeding methods in our county include captive breeding, cage breeding and grazing, among which most of the facilities for captive breeding and cage breeding are relatively simple, lacking unified planning and necessary pollution treatment facilities, resulting in direct discharge of livestock and poultry breeding waste and wastewater. Cattle and sheep mainly eat grass, and most of the feces are scattered on the hillside grass. These feces enter the surface water with rainwater, which pollutes the drinking water source.

2. The specialization level of rural drinking water treatment is low. Rural drinking water safety projects are generally small in scale and weak in management and technology. Although all towns have large waterworks to supply water and rooms to manage production and purification equipment, the existing waterworks managers are all temporary workers or rural contract workers, who have not received special on-the-job training, do not know much about the technological process of waterworks, have low professional level and have some problems to varying degrees. Other decentralized water supply and small centralized water supply generally lack water treatment facilities, disinfection facilities and water quality inspection equipment, and directly use source water without manual treatment.

3. The operation and management mechanism of rural drinking water projects is not perfect. First, the management organization has not been established. Only Lengshui Town in the county has set up a rural water supply project management association, issued a management method for township water supply projects, and incorporated village-level water supply into the unified management of market town water supply stations. Other towns and villages have not set up special rural water supply project management institutions, and village-level water supply has not been brought into unified management. Second, the management and operation funds are insufficient. It is difficult to collect water charges for centralized water supply in rural areas, which affects the long-term stable operation of water supply projects. Third, there is a shortage of management personnel. According to the requirements of rural safe drinking water management norms, water plant management needs purification equipment operators, pipe network maintenance personnel and meter reading and charging personnel. But at present, the rural drinking water project in our county is only managed by temporary workers, and there are no full-time managers.

4. The rural drinking water monitoring system is not perfect. Because the water sources of centralized water supply in rural areas of our county are scattered, there is no unified protection plan, the management responsibility of water source protection areas is unclear, and there are no routine monitoring points around the water sources. The pollution situation of water source protection areas is unclear, especially the pollution in rural rainwater harvesting areas lacks accurate and scientific data.

Three, to solve the problem of rural drinking water safety countermeasures and suggestions

Rural drinking water safety is an important livelihood issue. Solving the problem of drinking water safety in rural areas is an important part of implementing Scientific Outlook on Development, promoting the construction of new countryside and building a harmonious society, and is of great significance to ensuring the health and life safety of farmers, improving their quality of life and building a well-off society in an all-round way. Therefore, we must attach great importance to further strengthen the monitoring and protection of drinking water, pay close attention to the prevention and control of water pollution, effectively improve the quality and hygiene of drinking water in rural areas, and ensure that people can drink safe water, sanitary water and safe water.

1. Establish a long-term mechanism for rural drinking water safety management. The establishment of the county rural drinking water safety leading group, by the development and reform, finance, water conservancy, health, environmental protection, land, housing construction, forestry, agriculture and other relevant functional departments as members, specifically responsible for the organization and implementation of the county rural drinking water safety project and daily management, timely study and solve rural drinking water safety problems. Towns set up corresponding working institutions, set up a full coverage monitoring network for rural drinking water safety, and formulate emergency plans for rural drinking water safety to form a science.

Effective rural drinking water safety early warning and emergency response mechanism.

2. Improve the rural drinking water safety monitoring system. County health, water conservancy, environmental protection and other departments should strengthen cooperation, establish water quality monitoring centers and improve the drinking water safety monitoring system. Based on large centralized water supply stations, monitoring points are set up in different regions. For centralized water supply projects, strengthen the water quality inspection and monitoring of water source, factory water and pipe network end water. For decentralized water supply projects, water quality monitoring is carried out regularly in different areas. It is necessary to implement water quality monitoring institutions, personnel, tasks, responsibilities, equipment and funds to achieve smooth information and accurate and timely data. Every time obvious difference data is found in routine monitoring results, the reasons should be analyzed in time. If it is found that there are data exceeding the standard, it should be notified to the water conservancy department and the local town government in time, and the water conservancy department will decide whether to start the emergency plan according to the specific situation.

3. Focus on investigation, monitoring and protection of water sources. Organize relevant departments to investigate drinking water sources in rural areas, including water resources, water quality, water supply population, total population in surrounding rural areas, etc. Important water sources should be planned in a unified way, and management and protection should be strengthened. In particular, signs of protected areas shall be set up in the upstream 1 1,000m and downstream 1 1,000m of water intakes of centralized water supply projects to strictly control the discharge of domestic pollution sources, industrial pollution sources and agricultural pollution sources. For larger water sources, health, water conservancy, environmental protection and other departments jointly set up water quality monitoring stations, and set up regular monitoring points around the water source to effectively strengthen daily monitoring and ensure the water quality safety of the water source. It is necessary to formulate and implement the technical scheme for the prevention and control of drinking water source pollution in combination with practical science. In the construction of drinking water projects, the water conservancy department should first formulate the infrastructure construction plan of drinking water source protection areas, and set up boundary markers, boundary markers, publicity warning signs and isolation zones in the protection areas to reduce the risk of water pollution caused by people and animals entering and leaving the water source protection areas at will; The agricultural sector should actively promote the construction of sewage treatment facilities such as oxidation ponds, biogas digesters and wetland sewage treatment systems in rural residential areas, with farmers as the basic unit, focusing on the construction of "one pool and three reforms" (building biogas digesters, changing kitchens and toilets); Housing construction departments and township governments should combine the construction of new countryside, strengthen the construction of rural sanitation facilities and centralized treatment of rural domestic garbage and domestic sewage, and all garbage disposal sites must be built outside drinking water source protection areas; Agriculture, environmental protection and other departments should strengthen the management and guidance of livestock and poultry breeding, especially large-scale farmers, guide specialized livestock and poultry breeding households to build sewage treatment and reuse facilities and livestock and poultry manure treatment and utilization systems, strictly control rural point source pollution sources, and strictly prohibit the planning and construction of farms in water sources.

4. Strengthen the management and supervision of centralized drinking water projects. Management is an important factor affecting the quality of rural drinking water. Water conservancy department is the construction and competent department of drinking water project. It is necessary to pay equal attention to construction and management, strengthen sanitary management of drinking water, implement centralized production and processing of drinking water, and timely implement rectification measures to ensure the safety of drinking water for the people; The town government should set up water supply project management institutions, bring village-level water supply into unified management, formulate management and operation methods, technical specifications and operating procedures, implement full-time management personnel, conduct regular business training, and earnestly strengthen the management of water supply projects; Environmental protection departments should strengthen the monitoring of environmental water bodies and strive to create a high-quality and good water environment; The CDC should strengthen the monitoring of drinking water quality and timely grasp and analyze the changes of water quality; Health supervision institutions should earnestly perform their supervision duties, regularly carry out health supervision on all kinds of centralized water supply units, urge water supply units to do a good job in drinking water processing and production, especially disinfection management, and improve the qualified rate of drinking water quality.

5. Strengthen publicity and education on water environmental protection. Vigorously publicize water law, environmental protection law, water pollution prevention law and other laws and regulations and the significance of water environmental protection, enhance the legal concept and environmental awareness of the whole people, educate and guide the masses to realize that protecting water resources means protecting health, and consciously participate in and support water environmental protection and governance. At the same time, on the basis of relevant laws and regulations, formulate local laws and regulations suitable for rural drinking water source protection in our county, clarify the content and scope of rural drinking water source protection work, establish drinking water source protection management system and reward and punishment system, strengthen law enforcement supervision, and crack down on all kinds of illegal and criminal acts that destroy water sources according to law, so as to make water environment protection and construction on the legal track.

Drinking water research report 2 Water is the source of life, and obtaining safe drinking water is the basic requirement of human survival. Strengthening the protection of drinking water sources, improving the quality of drinking water and strengthening the safety of drinking water are important tasks related to people's life, health and safety, economic development and social stability. According to the work arrangement of the Standing Committee of the County People's Congress for 20xx years, * *, deputy director of the National People's Congress, led the Agriculture and Environmental Protection Committee to investigate the drinking water safety in our county, respectively, in the county water conservancy bureau, environmental protection bureau, water supply and drainage company and * * township. Now the investigation situation is reported as follows:

First, the drinking water status of urban and rural residents in our county

(A) the status of urban water supply

The drinking water of urban residents in our county adopts centralized water supply, and the second water plant in the county is responsible for water supply. The water plant is located downstream of the dam of the * * reservoir, with a design scale of 40,000 tons/day. The first phase of the water plant was completed in July, 20xx, with a scale of 20,000 tons/day. The water source is the middle layer of the * * reservoir. The water supply mode is gravity water supply, and the conventional treatment process in the 1970s is adopted. The process is that the raw water from the reservoir is transported to the clarification tank through the pipeline, then to the four-way valve filter for filtration, and finally to the clear water tank to become the finished water. At present, there are 20,742 water users with a maximum hourly water supply of 26,000 tons. Huiyuan Juice Cloud needs to increase the scale of 5000 tons/day after the company is completed and put into production. The existing urban water supply facilities can no longer meet the growth of water supply demand and residents' drinking water safety demand brought about by economic and social development.

(B) the status of rural water supply

Since 20xx, our county has carried out the construction of drinking water project for millions of farmers, with a total investment of 67.59 million yuan. Three centralized water supply projects (Yongtou Water Plant, Shitang Water Plant and Jinshuitan Water Plant) and 132 decentralized water supply projects have been built, and the rural drinking water guarantee rate has reached over 95%. At present, the county water conservancy bureau entrusts the county CDC to test the water quality, which basically ensures the safety of drinking water in rural areas.

(3) * * Status of drinking water source protection areas

* * The reservoir was built in 1959, with a storage capacity of 1 1.7 million cubic meters. It is a centralized drinking water source protection area in our county. In 20xx, the county government formulated the Environmental Protection Plan for Drinking Water Source of Yunhe County * * Reservoir, and established a leading group for drinking water source protection of Yunhe County * * Reservoir, with its office located in the Water Conservancy Bureau. In recent years, the county government has invested a lot of manpower and material resources to renovate the villages around the reservoir, carry out centralized garbage removal and domestic sewage treatment, and carry out unified agricultural prevention and control, effectively reducing non-point source pollution.

Second, the main problems

(A) Rural non-point source pollution affects the quality of water sources

The county government actively carries out environmental improvement of water sources, improves the ecological environment of water sources and improves the water quality of water sources, but it is still difficult to effectively eliminate non-point source pollution. * * The reservoir basin involves 6 administrative villages and 23 natural villages in * * Township, with 20xx people, cultivated land area 1 10,000 mu, bamboo shoot and bamboo forest area10.4 million mu. Residues such as fertilizers, pesticides and herbicides used in agricultural production, rural domestic sewage and wastes enter the water body with surface runoff, becoming the main pollution sources.

(2) Potential industrial pollution risk

Although there are no industrial enterprises in the water source area of our county, there are still some industrial pollution risks. The dust and smoke produced by Jin Wang Machinery Manufacturing Co., Ltd. opposite to the second waterworks in the county affected the quality of drinking water to some extent. At the same time, with the expansion of the south block of the industrial park, the distance between the industrial park and the water source protection area of the * * reservoir is getting closer and closer, and industrial production activities have a certain impact on the quality of drinking water sources.

(C) the drinking water source protection mechanism is not perfect

The county government attaches great importance to the protection of drinking water sources, but there are still problems such as imperfect long-term management mechanism, unclear responsibilities and insufficient funds. Water source protection restricts the local social and economic development, and the lack of ecological compensation mechanism has caused some resistance of local people to water source protection. The monitoring and supervision system of water quality of water source is not perfect, and the monitoring points and monitoring ability of the existing water source monitoring station network are limited, which can not meet the requirements of systematic and objective evaluation and effective supervision of water source. Water source protection involves many departments, such as villages and towns, environmental protection, agriculture and forestry, water affairs, education, health and so on. It is difficult for the Water Conservancy Bureau to coordinate all departments.

(4) The technology of urban water supply facilities is backward.

Water purification technology in waterworks is the core of drinking water safety guarantee system. The second waterworks in our county adopted the treatment process of 1970s, and disinfected the water by adding flocculant and liquid chlorine. It mainly removes pollutants such as turbidity, bacteria and microorganisms, and it is difficult to effectively remove pollutants such as ammonia nitrogen and trace organic matter, and it is difficult to effectively solve the contradiction between water pollution and the improvement of water quality standards, and it is even more difficult to effectively deal with sudden pollution incidents. At the same time, most of the early water supply networks used cast iron pipes and galvanized pipes. Due to the long service life, the pipeline is seriously corroded and aged, resulting in secondary pollution of water quality in the pipeline network.

(e) Rural drinking water management.

Since the implementation of rural drinking water project in our county in 20xx, the construction task has been fully completed, and the rural drinking water supply has been basically guaranteed. However, there are some problems such as imperfect long-term management mechanism after the construction. First, after the construction, the main body of operation management is not clear, the management funds are insufficient, and the water charges collected by the rural areas themselves are not enough to maintain the operation and maintenance costs of drinking water projects. Second, the decentralized rural water supply sources are scattered and small in scale, and there is no plan to protect drinking water sources, so it is difficult to carry out routine water quality monitoring. At the same time, most of the existing laws are aimed at centralized water supply, and the laws and regulations on environmental protection of decentralized water supply in rural areas are not perfect, which is difficult to meet the needs of rural environmental management. Third, some early construction projects were influenced by policies, funds and technologies at that time, and the construction standards were not high, and the reservoir safety prevention and disinfection facilities were not perfect. So far, they can't meet the people's production and living needs and health and safety standards, and they urgently need reform.

Three. Suggestions on ensuring the safety of drinking water

(1) Strengthen leadership and strive to establish and improve a long-term management mechanism.

Safe drinking water is a dynamic management process. With the continuous development of social economy and the continuous improvement of living standards, people pay more and more attention to the safety and health of drinking water. First, it is necessary to scientifically formulate the urban and rural drinking water safety guarantee plan, further improve the drinking water source protection and comprehensive management plan, and provide a basis for the future drinking water safety management in our county. Second, actively explore a long-term management mechanism to ensure drinking water safety, strengthen organizational leadership, enhance sense of responsibility, implement accountability, and provide organizational guarantee for drinking water safety. Third, the issue of ensuring drinking water safety will be included in the government's important agenda, special funds will be set up, the ecological compensation mechanism for * * water sources will be studied and established, and the ecological resettlement project for * * water sources protection will be accelerated; Accelerate the establishment of water quality early warning systems for water sources, water plants and pipe networks; Increase the protection and construction of water conservation forests, and constantly improve the water conservation capacity.

(2) Extensive publicity to raise the awareness of the whole people to protect drinking water sources. The protection of drinking water sources involves thousands of households, and it is necessary for the whole people to form a sense of * * * and enhance their awareness of protection. It is necessary to carry out extensive, in-depth and sustained publicity in the whole society through television, newspapers, internet and other media, and to create a public opinion atmosphere and a good environment for protecting drinking water sources. It is necessary to strengthen public opinion guidance and warning education on water source protection, constantly enhance the awareness of drinking water source protection and legal concept, and enhance the people's awareness of law-abiding and supervision. It is necessary to raise the awareness of protecting drinking water sources to a level related to the safety of people's lives and property, so that the whole society can fully realize that protecting drinking water sources is not only the work of government departments, but also the obligation of the whole people, actively participate in the protection, supervision and management of drinking water sources, and cherish the source of our lives.

(3) Control the source and increase the protection of water sources.

Drinking water safety is the basic "lifeline" of the people, so it is necessary to strengthen drinking water safety guarantee and ensure drinking water safety. First, we must strengthen the prevention and control of industrial pollution. Improve the access threshold of industrial enterprises to prevent the emergence of new pollution sources; Take practical and effective measures for existing pollution sources, strictly supervise and discharge up to standard, and avoid industrial dust and smoke from polluting drinking water sources. Second, strengthen the control of agricultural and rural non-point source pollution. Combined with the construction of new countryside, further improve the environmental protection infrastructure of * * water source, increase the treatment of livestock manure and production and domestic sewage in rural areas, accelerate the adjustment of agricultural industrial structure and production mode, popularize and apply advanced technology, prohibit the use of highly toxic and residual pesticides, and reduce non-point source pollution. Third, we should strengthen the centralized treatment of industrial wastewater and domestic sewage. Vigorously promote the construction of the second phase of Yunhe County Town Sewage Treatment Plant and supporting pipe network construction, improve the centralized treatment level of industrial park wastewater and county domestic sewage, reduce the impact on water bodies, and improve the water environment quality of our county. Fourth, we must strengthen the law enforcement inspection of water source protection. Improve the frequency of daily monitoring and inspection, accurately grasp the changes of water quality, eliminate hidden dangers of pollution in time, effectively put an end to the construction projects of water source protection areas and various activities that destroy the ecological environment and water resources and environment, and ensure the safety of drinking water sources.

(4) Expand capacity and improve quality to ensure the safety of urban drinking water.

We should conscientiously do a good job in the investigation and evaluation of urban drinking water safety and the analysis of future urban drinking water safety demand, and compile and improve the reconstruction plan of urban water supply pipe network. Actively introduce advanced water purification technology and advanced treatment technology of drinking water with stable treatment effect, intensify the transformation of water supply pipe network, eliminate the hidden danger of secondary pollution of water quality in pipe network and improve the quality of water supply. To increase capital investment, scientific arrangement, careful construction, speed up the expansion of * * water plant and urban water supply network reconstruction project construction progress, improve the safety and stability of water supply, and ensure the safety of drinking water for urban residents.

(e) Take measures to promote the management of rural drinking water projects after completion.

Realizing the long-term benefits of rural drinking water project and ensuring people's drinking water safety is an important content of rural drinking water project management in our county. First, strengthen organizational leadership, further implement management subjects, clarify management responsibilities, improve management measures, and ensure that rural drinking water projects are completed, managed, affordable and benefit for a long time. The second is to speed up the establishment and improvement of rural drinking water quality monitoring network, strengthen the water quality testing and monitoring of rural drinking water projects, and optimize the testing indicators and monitoring frequency. Third, on the basis of consolidating the achievements of existing projects, speed up technical transformation and improve the quality of drinking water; At the same time, it is necessary to do a good job in water source protection, set up publicity of water source protection points, and establish a special inspection system to ensure the safety of drinking water.

Investigation report on drinking water 3: Is the water we drink clean and safe, what standard it reaches, what happened in the process from nature to tap water, whether it was polluted, how much each link affected the final water quality, how to improve the drinking water quality, and how to establish a legal framework to protect the drinking water quality. These questions can be found in the white paper "A Drop of Water" written by "Jingze Project"-the investigation of drinking water quality in key cities in China. The electronic version of the report will be released in advance on March 22nd and officially released in Beijing on April 22nd, calling on the whole society to pay attention to drinking water safety.

A year-long visit, investigation and authoritative release.

With the improvement of people's living standards, more and more people begin to pay attention to the safety of drinking water. In recent years, great progress has been made in the construction and transformation of urban water supply sources, water purification plants and water supply pipe networks in China, and pollution source control and drinking water supervision and management have been continuously strengthened. But the problem of drinking water safety still exists. More seriously, the public has insufficient understanding of the water environment and drinking water safety, and still has doubts about whether tap water is healthy and safe and whether mineral water can be safely drunk.

In March of 20xx, in view of the drinking water safety situation in China, 2 1 Century Business Herald and Haoze Water Purification, with the academic support of the Sustainable Development Research Center of China Academy of Social Sciences, launched the water quality public welfare research project "Haoze Plan", taking "the course of a drop of water" as the linear investigation logic, that is, water source, waterworks, municipal pipe network, building pipe network, secondary water supply and sewage treatment, combined with supervision and industry standards. , and investigated the basic situation of urban drinking water sources, water quality and water pollution, protection and water pollution control, safe water use guidance, and suggestions for future water environment control, and finally wrote a report with guiding significance and practical value for public safe drinking water. The director of Haoze Water Purification Brand Center said that the national drinking water quality survey of key cities will be officially released in Beijing on April 22, but before that, the electronic version of the "Jingze Plan" will be released on March 22.

The safety of drinking water related to people's livelihood needs urgent attention.

At this year's two sessions, the topic of environmental protection has attracted much attention. As enterprises, institutions and even daily users closely related to water environment and drinking water safety, they must fully understand the current situation of water environment before they can participate in water environment protection activities with their own practical actions.

"Generally speaking, there are three links that affect the safety of urban tap water. The first is the quality of water source, that is, the quality of raw water; Second, from the effluent quality of the water plant, the water source to the water quality after the purification process of the water plant; Third, the quality of tap water from the waterworks to the water supply network. In these three links, the pollution of water sources is the biggest challenge affecting the safety of drinking water. " The report "Investigation on Drinking Water Quality in Key Cities of China" selected more than ten key cities (regions) in China, including Beijing, Shanghai, Guangzhou, Shenzhen, Harbin, Changchun, Shenyang, Hohhot, Xi 'an, Sanjiangyuan, Chongqing, Chengdu, Changsha, Wuhan, Zhengzhou, Hefei, Suzhou, Hangzhou, Jinan and Tianjin. As the survey object, it was found that "the water quality in some cities is unqualified. However, the report also pointed out that at present, the water treatment situation in all aspects is improving, from the water source to the waterworks to the water supply network.

"Let people drink clean water" has a long way to go.

At the end of 20xx, the Prime Minister inspected the Ministry of Water Resources and said: "Providing clean water to the people is the most basic livelihood guarantee, which is related to the credibility of the government and an unshirkable responsibility!" The investigation of a drop of water was led by authoritative media and socially responsible enterprises, and experts and scholars from the Ministry of Environmental Protection, China Academy of Social Sciences, china environmental science Research Institute, Hong Kong Polytechnic University, Tsinghua University, Darwin Environmental Research Institute, Green River Environmental Protection Association, Liangjiang Environmental Protection Center and other institutions, schools and NGOs participated in it, in order to make every drop of water in China safe to drink.

Professor Wang Zhansheng, a doctoral supervisor of the Department of Environmental Science and Engineering in Tsinghua University, deputy director of the Water Supply Committee of china civil engineering society Water Supply and Drainage Branch and chairman of the Water Supply Advanced Treatment Research Association, said, "It is a long way to go to solve the drinking water safety problem, and more people need to be called to pay attention to it. And "the course of a drop of water-the investigation of drinking water quality in key cities of China" is a timely and sincere appeal. It is hoped that more and more people will invest in water source protection, upgrading of water purification technology in waterworks and construction and renovation of water supply pipe network, and work together to provide more assured drinking water for the people. "

As a leading enterprise in the water purification industry, Haoze not only serves as the technical support unit of this report, but also shoulders the heavy responsibility of improving the quality of drinking water. In XX, Hauser will also carry out a series of public welfare activities, such as "smart water probe" public welfare distribution, and change people's drinking lifestyle with Internet thinking that always knows the water quality. At the same time, Haoze will also carry out volunteer activities in Sanjiangyuan with Green River.
