A homogeneous landfill consisting of dehydrated industrial chemical sludge containing metals was examined for two purposes, namely to assess the concentration and composition of the sludge by means of a suitable sampling method and to determine the “minimum number of samples” representing the system as a whole. The two methods proposed are based on statistical sampling techniques. The first made it possible to identify the presence of metals in concentrations higher than a set threshold on the basis of a limited number of samples. Once the maximum sampling error had been established, the second then made it possible to determine a sufficiently large sample size to ensure that this limit was not exceeded.

Abstract
A homogeneous landfill consisting of dehydrated industrial chemical sludge containing metals was examined for two purposes, namely to assess the concentration and composition of the sludge by means of a suitable sampling method and to determine the “minimum number of samples” representing the system as a whole. The two methods proposed are based on statistical sampling techniques. The first made it possible to identify the presence of metals in concentrations higher than a set threshold on the basis of a limited number of samples. Once the maximum sampling error had been established, the second then made it possible to determine a sufficiently large sample size to ensure that this limit was not exceeded.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
