Landfill Pollution Plume Survey in the Moroccan Tadla Using Spontaneous Potential

In many parts of the world, impact open landfills on soils, biosphere, and groundwater has become a major concern. These frequently generate pollution plumes, contours which can be delineated by non-intrusive geophysical measurements, but in arid environments, high soils resistivity is usually an obstacle, results low number studies that have been carried out there. addition, such prospecting using techniques do not provide information intensity processes occurring water table. This study was uncontrolled landfill Tadla plain, Morocco’s main agricultural region. A survey based geo-referenced spontaneous potential measurements combined with anoxic conditions (Eh-pH O2 equilibrating partial pressure) leachates, order to highlight plume its geometry. The range measurement wide, reaching 155 mV. Ponds leachate electrical conductivity (20 40 mS cm−1) form within landfill, present very reducing down sulphate reduction methanisation. slowly continuously supplied these highly organic carbon-rich leachates from landfill. Its direction towards N-NW, stable throughout season, consistent local knowledge flow. fast flow table suggests over long distances should monitored future. obtained are spatially contrasting stable, show used resistive medium environments.
