Impact of debris from demolition of Boumerdes on the quality of groundwater

Abstract

The public discharge of Boumerdes city is at 5 km from downtown at Tidjelabine site and marly-calcareous formation. This formation shows crack porosity that facilitates pollution of groundwater reserves. The slope character of the field also favours the movement of pollutants. Leachates penetrating from the discharge towards the water table result in water quality deterioration. Chemical analysis carried out on samples from three piezometers show large concentration of chromium, zinc and lead, thus confirming the high groundwater deterioration. To assess the degree of pollution caused by this discharge, a comparison with other similar discharge was studied. This shows that the site is ancient of the discharge and is not stabilized yet and an acidic phase of anaerobic degradation is still going on. bacteriogical analysis carried out on groundwater show a microbiological contamination
