Impact of Landfill Leachate on Groundwater Quality – A Comparison Between Three Different Landfills in Morocco

Abstract

In this work, physicochemical and bacteriological analyses of leachate collected from three different landfills in the Marrakech region in Morocco were carried out. The results showed that the leachate is highly loaded with organic matter, chemical and bacteriological elements and some heavy metals, this load depends of the nature of landfill (rural or urban) and also of its age (young or old), the values of the parameters exceed the limit values for discharge into the natural medium. Physicochemical and bacteriological analyses of groundwater from wells downstream of these landfills were also carried out; The results showed that they had medium to poor quality according to the type of landfill. This is due to the presence of organic matter, total coliforms, total phosphorus and total nitrogen in many studied wells.

The Effect of Eco-Enzyme Spraying on Suwung Landfill Waste, Denpasar, on Changes in Leachate Characteristics

“…2023;15(1):56-66. https://doi.org/10.20473/jkl.v15i1.2023. [56][57][58][59][60][61][62][63][64][65][66] nitrogen, and other pollutants in the form of suspended particles and dissolved solid contaminants (8)(9)(10). Leachate has the potential to contaminate groundwater and the environment due to the high quantity of toxins it contains (8,11).…”

“…Leachate contains a high concentration of organic ingredients, chemical and bacterial elements, and heavy metals. Direct discharge into nature without any treatment will cause water pollution (49,56). Leachate water coming from landfills is a serious problem.…”

A Review on the Adsorption of Phenol Derivatives from Wastewater

“…Groundwater can be polluted by several sources of pollution namely landfills (leachate) [Benaddi et al 2022c] WWTPs (domestic and industrial wastewater) [Osmane et al 2023] or olive mill waste water, these effluents contain in addition to organic matter other toxic elements such as phenol derivatives. Phenol is one of the first constituents of the large family of aromatic organic compounds, it is composed of a benzene ring connected with a hydroxyl group.…”
