The use of hexadecyltrimethylammonium (HDTMA) bentonite, benzyltriethylammonium (BTEA) bentonite, shale, and granular activated carbon as a sorptive amendment in compacted liners by using laboratory sorption and permeability testing was discussed. A genetic algorithm optimization model was developed and used to design a liner containing sorptive amendments. Results from the laboratory sorption experiments indicated that granular activated carbon exhibited the highest sorptive capacity for the three solutes tested. Results from the optimization analysis indicated that the inclusion of sorptive amendments as a component in compacted soil liners could effectively minimize the transport of organic contaminants.
