Four polyethylene based vapor barriers and six different geomembranes were examined for their diffusive properties with respect to benzene, toluene, ethylbenzene, and xylenes (BTEX). All four vapor barriers performed comparably. Of the geomembranes tested, high-density polyethylene (HDPE) showed the greatest diffusive resistance to BTEX, while polyvinyl chloride (PVC) showed the least, LLDPE (linear low-density polyethylene), CSPE (chlorosulphonated polyethylene) and two KEE/EIA (ketone ethylene ester/ethylene interpolymer alloy) geomembranes all performed similarly, bounded by HDPE and PVC. Based on data collected at 22, 30, and 40 degrees C, Arrhenius relationships are presented for the six geomembranes. Each geomembrane was evaluated for performance as a diffusive barrier in a landfill cover scenario. Each vapor barrier and two geomembranes were evaluated, through contaminant transport modeling, for performance as a diffusive barrier to vapor intrusion into a warehouse and substantial potential differences in performance are reported.
