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.

Several environmental companies consider phenols compounds to be very dangerous pollutants because they are highly toxic and non-biodegradable, notably their high toxicity in water. For this reason, several processes have been studied by researchers to understand the mechanisms of elimination of phenolic compounds. Adsorption remains the best technique due to its characteristics, in fact, it is non-destructive and simple to use as well as have more other advantages, such as practicality and efficiency and low cost, Therefore, these methods need to be widely developed on an industrial scale to remove phenol derivatives and achieve wastewater quality in accordance with standards. On the other hand, the development of these adsorption methods is highly dependent on new research on materials from abundant natural resources, namely apatites or biomaterials.
