Montmorillonite clays in amounts above 3% by weight may be expected to reduce effective permeability of pure sands to fresh water by 100% or to practically zero for sands with the grain size distribution with mean of 0.30 mm and standard deviation of 0.18 mm. Kaolinite clays in amounts above 16% by weight may be expected to reduce the permeability of similar sands to practically zero.
