This afternoon, "I measured for the home river" Environmental Action Report will be held in Beijing, and China released a university student version of part of the river water pollution map. The report concluded that, from the river water quality data, the overall water quality of the river is poor investigation, which inferior class V water accounted for 46% of all water samples, 82% of the water does not reach the local level of planning. By the end of 2014, the ministry announced the "2013 China State of the Environment." The communique noted that in 2013 the country was mild overall surface water pollution in some cities seriously polluted river. In fact, our local surface water has improved, but is still in the continued deterioration of some basin states.

From January 1, 2015, more stringent new "environmental law" came into effect, including new chapter "Information disclosure and public participation." Article 53 of the "citizens, legal persons and other organizations are legally entitled to access to environmental information, participation and supervision rights of environmental protection.
In this context, for verification of the status quo of river water quality Chinese, "I measured for the home river" Starting environmental action. Activities collect from Beijing's major colleges and universities students as volunteers (few foreign college students), use the summer time to return home, according to the norms retrieve water samples by professional testing organizations, water samples intuitive data validation China Water Environment Pollution Situation, in conjunction with the questionnaire survey form local river environment change situation.
The event sampling program elements for each river take three samples spaced sampling time; sampling location, sampling mode as much as possible in accordance with industry norms; sample shall within 48 hours courier to detection mechanism, no more than 72 hours of special circumstances; test items the pH value, COD, permanganate index, ammonia nitrogen, total phosphorus, dissolved oxygen, volatile phenol, petroleum, hexavalent chromium, arsenic, lead, mercury, some rivers plus seizure stupid amines, nitro stupid class.

Events in May to start the registration, a total of more than 2,000 college students submitted online registration information, the organizers based on watershed distribution, the selection of the 100 volunteers involved in river sampling basics training, and finally a total of 50 volunteers selected sampling work. To the end of October, the final recovery activities effective water samples 28 samples of a total of 79 points, and on the sampling of the many rivers of text, images, data. All water samples by the testing organization detected in time, according to expert opinion, 79 water samples to detect a statistical report data, analysis, and refer volunteers to practice reports, residents of the residence questionnaire provided information, generate reports.
In the report the scene, he has been involved in the investigation of river environmental protection science and technology news reporters Beijing Cheng Li of the report in-depth interpretation.
The report concluded that, from the river water quality data, the overall water quality of the river is poor investigation, which inferior class V water accounted for 46% of all water samples, 82% of the water does not reach the local level of planning;
From the overall ecological river, the overall situation is still deteriorating, 40% of respondents believe that aquatic plants, trees and the river has decreased or significantly reduced; for aquatic understanding of respondents believe all fishermen have reduced or aquatic animals significantly reduced, and changes in water quality is the main reason.
65 percent of residents believe that water pollution affect their lives, more than 60 percent of residents believe that water pollution impact on health; it seems from the perspective of public participation, residents of the water environment has a higher enthusiasm, but there is no effective learn canal water environmental information and reflect water pollution sources.
However, the organizers also stressed that due to limited conditions, sampling mode, etc. is difficult to achieve the number of national environmental monitoring standards, data and conclusions presented at present and can not be equated with the sampling of the river is completely real situation. And the Ministry of Environmental Protection released the "2014 China Environmental Bulletin" than the right, the survey sample is not something that many state-controlled section of the surface, the overall water quality slightly worse than the state-controlled sections, but the main pollution indicators COD, five biochemical oxygen demand and total phosphorus and "Bulletin" consistent, for some time, sewage treatment and perhaps should be the focus.
China University of Political Science student Tong Yang Hong, Beijing University of Aeronautics and Astronautics student Huan known as volunteer representatives shared their participation in the activities of the feelings and thoughts; Peng Teng researcher and Professor Song Guojun, respectively, the survey results, the effectiveness of the activities in a professional review.
Peng Teng believes that in order to college students as volunteers, "My hometown measure river" environmental action taken by random river water samples for analysis and the use of local public opinion survey in two forms, the realization of the merits of the investigated water quality of natural rivers evaluation and social evaluation. Survey results can be more truly reflect the natural environment investigated river and its ecological function of utilization, in line with the latest requirements of the State Council, "Water Pollution Prevention Plan action". The environmental action only enrich the environmental practices of college students, but also for the random sampling verification status of surface water quality in China provide a useful public participation.
Song Guojun believe that students learn through standardized questionnaire hometown river situation is both a good way to cultivate talent, but also students to love the home, specifically in the form of home made contributions to the protection of the river. The results of the survey is worrying, though not enough to monitor the results with local government than right, but the explanation of the difference between the status quo, or remind us of the need to continue our efforts. I hope that this attempt to continue, can quickly change the concept of people do not work hard to improve river water quality, while promoting China to speed up the implementation of the management system in accordance with the river basin management mechanism.
"I measured the river for the home," a college student science writing practices carried out by the Beijing Popular Science Writers Association, aims verification environment and water quality status of Chinese rivers, and promote public participation in environmental protection, culture and discovery science invasive passengers. Activities by professional science Media Technology newspaper Beijing organizations, activities throughout the environment by the National Research Center for Urban Pollution Control Technology researcher Peng Teng, professor of Renmin University of China School of Environment Song Guojun guidance and support.
