The work presented in the current research relates to the retention of heavy metals detected in both the leachates of the unmonitored public dump of the town of Sidi Bennour, and in the subterranean water of a few wells in the area surrounding the dump. The chosen method was percolation-filtration through the use of a 1.5m high vertical column that was 25cm across. A filtrating matrix option was chosen in line with several physical criteria including the speed of the leakage, its porosity, and in particular the granulometric size. We used agricultural clay soil as a filtrating support as well as fly ash, household ash (clinker) and marine sand with a granulometric size of 100 μm. The main parameters analysed by ICP for the study were Cd, Cr, Cu, Fe, Pb, Zn and the findings were highly satisfactory: they showed a very significant reduction in toxic heavy metals. To validate our findings, the ICP analysis of the filtrate was compared with that of drinking water. The purified liquid that we obtained could perfectly well be used for industrial requirements as cooling liquid or for irrigation, and the filtration sludge was repurposed for use in construction – to make paving stones and building blocks.
