| The Application of DRASTIC and Isotope Method to the Evaluation of Groundwater Vulnerability in Hohhot, Inner Mongolia |
| Taking the plain groundwater system of Hohhot in Inner Mongolia as an example, the authors made vulnerability division of groundwater system by adopting the traditional DRASTIC and some new isotope dating methods based on concentrations of 3H, 3H and 14C. The methods of vulnerability evaluation of groundwater system were investigated. The evaluation results of the DRASTIC show that the shallow groundwater system can be protected against the pollution in vertical direction. The evaluation results of the isotope methods show that the shallow and deep aquifer system can be protected against the pollution from recharge areas. This paper also points out the respective advantages and disadvantages of the two means. Finally, it is pointed out that DRASTIC and isotope-assisted methods should be adopted on the basis of regional hydrogeological conditions, current groundwater exploitation situation and city development planning for comprehensive zoning of groundwater systems. The evaluation provides scientific guidance for environmental management, helps policy makers divide protection zones of underground water sources and work out groundwater protection measures. |
