Drinking water source protection zone delineation technical specifications will
Formulated and promulgated by the State Environmental Protection Administration of the "drinking water source protection zone delineation technical specifications" will be February 1, 2007 into effect. This standard provides for surface water drinking water source protection zones, groundwater drinking water source protection zone delineation of the basic method and drinking water source protection zone delineation, preparation of technical documentation requirements, is the pollution of drinking water control to ensure the safety of drinking water guidance standards. Recently, the reporter of "norms" of the problem interviewed State Environmental Protection Administration and Technology Standards, responsible person.
The official said the relationship between drinking water security of millions of people's health, ensure drinking water safety, meet people's increasing demands of drinking water to ensure the health of the people is "people-oriented, building a harmonious society and realize the man and nature and all-round, coordinated and sustainable development "priority. In order to implement the "Guidelines for the implementation of scientific concept of development and strengthening environmental protection decision" on "and adjust to scientific delineation of drinking water source protection areas, strengthen the protection of drinking water sources, build the city back-water, to solve rural drinking water safety issues" requirements, the establishment of drinking water source protection areas to protect drinking water sources from human activities as possible, an important measure to ensure water safety.
Speaking of "normative" role, the official told reporters: pollution management in 1992, State Environmental Protection Division issued the "Outline of drinking water source protection zone delineation," provided the drinking water source protection zone delineation of the basic technical requirements. Since then, some provinces and cities designated in accordance with the requirements of the drinking water source protection areas and in different forms by the Government or the National People's Congress for approval. However, the lack of uniform technical standards for the division, arbitrary delineation of protected areas around the large, restricted to some extent play the role of protected areas. In order to grasp the drinking water source protection area delineation problems, the State Environmental Protection Administration, Chinese Academy of Environmental Sciences Organization, China Environmental Monitoring Center and the China University of Geosciences of the experts on the situation of environmental protection for drinking water research. Through the study found that four prominent issues: First, the delineation of protected areas, specification, instruction and evaluation methods seriously lagged behind the division throughout the different evaluation criteria, it is difficult to achieve standardized management; second division due to lack of protected areas, technical specifications, program set of protected areas are designated areas are mostly water and land, without a scientific basis, science is poor, the role of protected areas can not be given full play; three delineation methods are not uniform because the management system is not clear, local fragmented, self-development division method, in relation to transboundary water resources, because of the delimitation of protected areas and management reasons, leading to disputes about the upstream and downstream; Fourth, the economic and social development and continuously growing urban population, in order to meet increasing water demand, water quantity to the quantity of water and the rapid growth of the original demarcation of protected areas has been mostly can not meet the requirements to protect water sources, drinking water source protection areas need to be adjusted or reclassified.
