The compatibility of chemicals in the leachates with the three natural and artificially -made liner materials is analyzed by performing the laboratory hydraulic conductivity test. The selected liner materials are natural marine clay, fly ash and weathered granitic soil stomped from Kimpo Wastefills, Seochon power plant and Mansu Dong, Inchon, respectivaly. Bentonites of 20 and 10 percent by weight are used as additive materials for fly ash and weathered granitic soil and the chemical solutions used in the test are acetic acid, methanol, heptane, and aniline which are frequently found in the leachate of waste fills. The concentrations of the chemical solutions are 100% and 75%. The results of the tests show that hydraulic conductivities of the oxter materials are increased by one or two orders of magnitude with permeating pure chemical solutions. The rate of hydraulic conductivity increase is lowest for Seochon fly ash admixed liner and highest for natural marine clay liner. The influence of hydraulic chemical solutions on the liner materials is least for acetic acid and largest for aniline. The increases of conductivity are not shown with the permeation of the solution of concentration 75%. At least by this test results, it can be recognized that the tested liner material can be quite stable with the solutions of significantly high concentration except pure solutions.
