Groundwater Environment Health Risk Assessment Method Research And Example Analysis

Water is the basic life-sustaining material of human beings. It is an important and indispensable resource for industrial and agricultural production as well as urban development. Human beings are accustomed to believe that water is a kind of inexhaustible and cheap natural resource, but with the population expansion and economic development, water shortage have emerged in many areas. Shortage of water resource is exacerbated by water pollution, which threatens human’s health. It is necessary to combat water pollution effectively, and to protect water resources. It has become an urgent task of human beings. The health risk assessment is an emerging tool that connects environmental quality with human health. Groundwater environmental health risk assessment is an important branch of the environmental risk assessment, through the implementation of its method, the comprehensive grasp of the groundwater can be more scientific and objective, human beings can keep abreast of groundwater security. It can help to strengthen the groundwater health risk management. Thereby the corresponding priority control strategy and environmental protection strategy can be implemented based on the evaluation results. The thesis briefly introduces the basic theory of the health risk assessment, which will be a basis for the establishment of groundwater environmental health risk assessment model, based on the water quality monitoring data of Li Guanpu, the thesis will have a quantitative evaluation of the groundwater environmental health risks, and conduct a detailed analysis of the assessment results and processes, based on these to guide the corresponding risk management.
