Evaluation of the Impact of A Domestic Waste Landfill on Groundwater Quality in North China
In order to solve the problem of groundwater pollution caused by the diffusion of landfill leachate in simple do-mestic refuse landfill under the action of precipitation or groundwater seepage movement.This paper takes the investigation of a landfill site in North China as an example,and on the basis of data collection,informed per-sonnel interview and hydrogeological investigation,identifies potential pollutant characteristic indicators,sci-entifically and reasonably arranges groundwater sampling points to collect groundwater samples.Based on the single factor pollution index method,using the Class IV standard indicators in the"GB/T 14848-2017 Groundwater Environmental Quality Standards"as the evaluation criteria,by comparing and analyzing the wa-ter sample test results of the upstream control point,vertical groundwater flow diffusion point,and down-stream diffusion point of groundwater,the distribution and diffusion range of pollutants in the landfill site were identified.
