| A Method for Evaluation of Pollution Risk of Karst Groundwater by Source Runoff |
| In the past, the methods for risk assessment and prevention of karst groundwater pollution proposed both in China and abroad have been all based on the theoretical method of groundwater vulnerability assessment. These methods divide the karst water zone into many parts by pollution danger assessment, and then carry out the preventive and control measures accordingly. Such methods of dangerrisk and prevention assessment are aimed at the karst water evaluation, especially in a large area, and therefore the evaluation results as well as the preventive and control measures have poor pertinence as there are many specific karst water sources. In southern China, the karst areas are characterized by concentrated periods of rainfall, rapid water circulation and uneven water sources distribution and are easily polluted. Therefore, this paper proposes an evaluation method of “Source-Pathway-Target-Value” (SPTV) for risk assessment of karst water pollution. This method is designed on the basis of the comprehensive consideration of water sources (pollution target), pollutant sources, pollution pathways and Losses caused by pollution. The pollution control measures are put forward from the perspectives of controlling pollutant sources, cutting off pollution pathway and protecting karst water sources. These measures have strong pertinence, operability and a good prospect of application, thus overcoming the shortcomings of existing methods. |
