Effect of Leachate containments on Clay liners

Abstract

Clayey soil is made up of extremely tiny clay particles that can be employed as a binding material and have a higher retention of water compared to other soils. A hydraulic barrier to fluid flow can be obtained by a clay liner. Clay liners serve a purpose in liner systems to regulate leachate release from the waste or in covering systems to reduce water infiltration. Long-term low hydraulic conductivity constitutes a demand for clay liners to accomplish these objectives. Clay liners were barriers designed to cover landfills and dispose of low and intermediate-level waste. clay sample of its index and engineering characteristics permeability will be examined in a laboratory. After adding Na, Cl (salts) and Mg,Cr,Zn,Pb (metals) at different percentages to the clay soil the Hydraulic conductivity and index characteristics are examined within lab conditions. The measured values of the sample's including before and after the addition of chemicals at different percentages 0,2,4,6, and 8%, have been compared by the results of the present investigation.
