Research Of Groundwater Vulnerability Assessment And Prevention Countermeasures In Handan City

At present, the groundwater pollution becomes a widespread public problem. As the economic social development and the deepening of industrialization, more and more problems in groundwater environment is becoming. According to the investigation and monitoring results, groundwater of about half of the city in China is polluted. So groundwater quality deteriorates. At the same time groundwater contamination present in from city to rural expansion trend and water. Shortage city and region caused by groundwater pollution is growing. Due to groundwater pollution's control and water environmental recovery is a long, difficult process. To solve the pollution of groundwater is the most effective method of preventing groundwater pollution. In recent years, groundwater vulnerability assessment method in many countries has been widely applied. The evaluation results of groundwater pollution is basis for control groundwater resources"s rational utilization and decision-making. This paper studies groundwater protection in Handan. This paper studies Handan protection of groundwater, find out Handan city's groundwater pollution causes and pollution forms and evaluates the vulnerability of the groundwater in Handan.Quality evaluation and pollution evaluation use the comprehensive index method. Quality evaluation can evaluate the quality grade of groundwater quality in Handan. According to the results of the evaluation of groundwater, quality evaluation map is drew. Evaluation of pollution status obtains the regional pollution, thereby groundwater pollution evaluation's map is drew. Take measures to the serious pollution's area. Groundwater vulnerability assessment uses DRASTIC evaluation method combining with the fuzzy evaluation of the study area. Through the DRASTIC method eight areas are classified into5grades. Then for each grade area further sorted, further illustrate the antifouling performance. Then use fuzzy evaluation grades for each region. Further illustrate the antifouling performance. It is the basis for the control of groundwater's pollution and groundwater protection's policy.Finally, put forward the protection of groundwater in view of Handan.
