Non Point Source Pollution

Nowadays, agricultural non-point source pollution has become the main pollution source of water environment, especially for drinking water. Water sources protection has become a major problem in national economy and people's livelihood. Rural contiguous improvement project, including rural drinking water source protection, rural domestic sewage treatment, rural living garbage and livestock industry pollution treatment, can not only improve rural living environment, but also effectively reduce the non-point source pollution source of the water sources. A case study in north China showed that, after rural contiguous improvement, the amount of pollution source reduced significantly, so as to protect and improve the environmental quality of water source reserve effectively.

Non Point Source Pollution

Non-point source pollution risk assessment for surface drinking water catchments is an important basis and premise for the scientific management over water environment, while remote sensing technology may timely find the spatial distribution pattern and variation of risk. Coupling the Non-point source model and remote sensing data is a potential method for the water environment risk assessment. The dual Non-point source model independently developed by China is chosen to study its practical applicability in the experimental catchment area of Hebei Yuecheng Reservoir in combination with the remote sensing and GIS data, and to study the spatial distribution pattern of the Non-point source Phosphorus (P) pollution generated by the spatial landuse. The result shows that:(1) the coupled model is well adapted to the catchment area of Hebei Yuecheng Reservoir, and the simulated Non-point source P load is strongly related to the observation data of the hydrologic stations such as Liujiazhuang, Guantai and etc.; (2) The disorderly development of social economy is the main cause of Non-point source pollution, and the farmlands, urban and rural residential areas in the catchment area are the major risk sources of Non-point source pollution; (3) the two assessment units, catchment unit and administration unit, are employed in this study. They are complementary to each other, which is convenient for management because they can reflect not only the P risk distribution but also the specific location of the administration areas within the risk area.

Non Point Source Pollution

Wohushan reservoir is an important drinking water source for south urban area of Jinan, however, the water quality of Wohushan reservoir is not safe, and agricultural non-point source pollution is the main reason that caused the water quality deteriorate. This paper analysed the sources of non-point source pollution through datum of population and agriculture production and other economic and social activities in Wohushan reservoir area. The water quality effect of domestic sewage, house refuse, live stock dung, and unreasonable use of fertilizer and pesticide were discussed as emphasis. Further more, the factors of the non-point source pollution were summarized according to policy, statute, economic, technology etc. At last, countermeasures of non-point source pollution prevention and control were proposed based on the source and pathway control of contaminates including perfect law system, strengthen policy guidance, increase funding, use fertilizer and pesticide reasonably, popularize biotechnology and methane tank, carry out efficient eco-agriculture construction, etc.
