Calculation of hydrogeological parameters and valuation of groundwater quality in Dongwudou Village, Laiwu District

In order to solve the groundwater exploitation and utilization in Dongwudou Village, Laiwu District, hydrogeological parameters and groundwater quality are urgent problems to be solved. The influence radius R and permeability coefficient K, the key hydrogeological parameters of the aquifer, were calculated by single-hole steady flow pumping test. The results show that the influence radius of Dongwudou Village in Laiwu district is 153.38 m, and the permeability coefficient is 2.27 m/d. The groundwater quality was evaluated by single factor evaluation method, comprehensive index F value scoring method and Nemerow comprehensive index method. The results of different evaluation methods were consistent, that is, the groundwater of Dongwudou Village belongs to class III water with good water quality and can be used as a direct drinking water source for residents.
