Testing of Leachate Levels at a Landfill with Multiple Intermediate Covering Layers
There is no leachate level testing method for a landfill with multiple intermediate cover layers.This paper provides an in-situ testing method for multi-layer perched leachate levels.In-situ tests were carried out at a landfill with multiple intermediate cover layers and the perched leachate level on each intermediate cover layer were obtained.The testing results showed that:(1)by drilling to a position 1–2 m away from the cover layer,the well casing was positioned and the in-well casing leachate level was reduced to the well casing bottom,and the leachate level recovery was observed so that the steady leachate level of this layer could be measured 24 h later;(2)the perched leachate level height on each intermediate cover layer were not consistent;(3)the low-permeability intermediate cover layers were the main course of the formation of the multi-layer perched leachate levels.
