WebThe cation exchange capacity (CEC) of a GCL is small when compared to a clay liner. In essence, where a barrier is required that requires either an absorptive capacity or a long breakthrough time, a GCL alone will not provide adequate protection. In these circumstances, a design will also need a low permeability attenuation layer. cherryfield lodge nursing home dublin
