Investigation and Evaluation of Soil and Groundwater Pollution in a Simple Landfill Site in Hunan Province
The soil and groundwater of a simple landfill in Hunan Province were sampled and investigated,and the environmental quality was analyzed and evaluated.The results showed that both heavy metals and Volatile Organic Compounds(VOCs)did not exceed the second-class land risk screening value in the"Soil Environmental Quality Risk Control Standard for Soil Contamination of Development Land"(GB 36600-2018),while arsenic,total coliform bacteria and total dissolved solids exceeded the Ⅲ class water standard limit in the"Standard for Groundwater Quality"(GB/T 14848-2017).The results of soil evaluation show that the Nemerow comprehensive pollution index of soil evaluation within the scope of landfill is 0.042~0.380,and the Nemerow comprehensive pollution index of soil samples around landfill is 0.043~0.756,all of which are less than 1.The results of groundwater evaluation show that the comprehensive pollution index of groundwater in landfill site ranges from 2.72~17.06.Groundwater pollution around the landfill site is far more serious than soil pollution.
