Permeability of Vacuum

Further studies had shown that substantial reduction of fumigant emissions could be achieved by adopting new low permeability barrier films or using methyl bromide and chloropicrin mixtures with lower concentrations of methyl bromide.

The permeability of the underlying layer is less (lower) than that of the geological formation in the aquifer.

Hence this barrier
