Experimental results, carried out at the Mining Science Institute of the University of Bologna, about performances of clayey soils as hydraulic barriers against aquifer pollution are given. In particular, laboratory measurements of the filtration effects of various chlorides on permeability of a set of artificial samples, prepared with a natural sand and four different types of clay, are examined and discussed. The paper shows the basic differences in the behaviour of clayey layers in presence of different solution and the importance of determining their actual efficiency as aquifer protective layers.

Abstract

Experimental results, carried out at the Mining Science Institute of the University of Bologna, about performances of clayey soils as hydraulic barriers against aquifer pollution are given. In particular, laboratory measurements of the filtration effects of various chlorides on permeability of a set of artificial samples, prepared with a natural sand and four different types of clay, are examined and discussed. The paper shows the basic differences in the behaviour of clayey layers in presence of different solution and the importance of determining their actual efficiency as aquifer protective layers. The necessity of standardizing permeability measurements is also highlighted.
