Preliminary partition of groundwater protection zones by empirical formula method

Groundwater is an important source for water supply. However, the environmental protection measures and pollutant treatment technology have not greatly improved, and people's awareness of environmental protection is not enough, groundwater environment is suffering serious damage and groundwater quality is undergoing obvious deterioration. The present study focused on the delineation of groundwater quality protection zone. In this paper, the empirical formula method is used to preliminarily divide the groundwater protection zones in No. 2 Groundwater source in Dawukou District of Shizuishan City, China. And three levels of protection zones were divided reasonably. The first level protection zone is 4.53 km², the second level is 5.71 km² and the third level is 25.02 km². Seen from the results, the Empirical formula method is a simple method to partition the groundwater source protection zones, which is also economic and easy to carry out. The divisional results is reasonable and reliable, it provides the scientific basis for the development and protection of water resource in the study area. Also the study can help to guarantee the safe operation of the water source and realize the sustainable development of water.
