Abstract
A conventional Geosynthetic Clay Liner (C-GCL) and a dense prehydrated (DPH) GCL were permeated with an acidic solution (pH=2) containing relatively high concentrations (0.025 M) of Pb, Zn, and Cu as nitrate salts. Both GCLs were permeated with distilled water prior to exposure to the metal solution. The DPH-GCL preserved hydraulic conductivity about one order of magnitude lower than the C-GCL. Breakthrough of metals occurred within three months of permeation for the C-GCL whereas it was not complete after more than one year of permeation for the DPH- GCL material. Cation exchange and precipitation of metals were the likely retention mechanisms.
