| Risk Assessment and Control Countermeasures of Southern China’s Karst Groundwater Areal Source Pollution |
| There are about 800 000 km2 carbonate formation, 3 620 karst groundwater systems and 1 806×108 m3/a karst water resources in southern China, which supply water for about 50 million urban residents and more than 8 000 rural people in 69 cities of southern China. However, karst water has been polluted in different degrees, and the agricultural areal source pollution is far more serious than the non-areal source pollution for karst water, which will threaten the water supply security in karst areas. Therefore, the risk assessment study of karst groundwater pollution is of great significance. Based on comprehensive and systematic analysis of the characteristics, the pollution types and pollution ways of southern China’s karst water, and consulting the existing experimental results, the authors summarized the protective capability against pollution of karst ground water, and proposed the methods for pollution risk identification, the pollution probability estimation, the pollution risk assessment and control. With Guiyang as an example, the authors evaluated the karst groundwater areal source pollution risk, and put forward prevention and control countermeasures according to the characteristics of the karst groundwater areal source pollution. |
