Analysis of the environmental status of groundwater in a gully-type domestic waste landfill
Taking a gully-type domestic waste landfill site as the research object,integrating the hydro-geological con-ditions of the site,investigating the groundwater environmental conditions around the research site by means of field investiga-tions,sampling and data analyses,identifying the current status of the groundwater environment,and researching the reasons for the exceeding of the groundwater standard and the impact of the landfill site on the groundwater environment.The results show that:The type of groundwater in and around the landfill is loess submerged and valley submerged.After sampling analy-sis,it can be seen that the groundwater samples of the three groups of loess hilly area and the three groups of river valley area are Class V water,and the exceeded indicators are sodium,chloride,sulfate,total hardness and dissolved total solid,which is caused by the high natural background value of groundwater exceeded the standard.The multiples were 0.16～0.41,0.07～0.83,0.47～2.77,0.12～0.91,0.08～0.55;According to the analysis of the comparative leachate and groundwater sample test results,the domestic waste landfill has no impact on the surrounding groundwater environment,and the groundwater exceedances are all caused by natural reasons.
