The aim of this study was to assess the impact of the reuse of purified wastewater from the wastewater treatment plant in the city of Settat on the physicochemical quality of agricultural soils compared to the agricultural soils irrigated by rainwater in the region of Chaouia in Morocco. The results obtained showed that despite the great fertilizing value of the purified wastewater, a slight increase in salinity was noted; they also reveal a significant difference in pH. The accumulation of sodium, total limestone and active limestone in the soil increased significantly in the soils irrigated by treated wastewater; in contrast, calcium increased significantly in the soils irrigated by rainwater.No significant differences were recorded for humidity, electrical conductivity, ammonium, nitrates, phosphorus, potassium, organic matter, total nitrogen or cation exchange capacity.

In Morocco, solid household waste is often disposed of in open air in unsuitable sites, causing adverse effects on humans and the environment. In the province of Settat, there are eight uncontrolled landfills. The present study aimed to determine the most suitable sites from an environmental and economic point of view to ensure good management on a regional scale. The investigation involved a combination of a multi-criteria method (the AHP analytical hierarchy process) and a GIS geographic information system (ArcGIS) with ten criteria: distance from the ground water, water surfaces, drilling, settlements, forests, roads, highway, land use, slope, and elevation. The suitability map showed that about 18.5% of the study area is suitable for installing a sanitary landfill.

In Morocco, the population growth and changes in consumption and production patterns are increasing the amount of generated waste, particularly household solid waste. It is estimated at 6.9 million tons per year, of which 5.5 million tons in urban areas, with a ratio of 0.76 kg/inhabitant/day (Ministry of the Interior, national portal for local authorities, National Household Waste Program). In the absence of controlled landfills, this waste negatively affects living spaces and generates health and environmental problems. The province of Settat, which is affected by this scourge, inefficiently manages this household waste as in other regions, thus requiring improvement with the involvement of the actors concerned. This work involves the creation of a cartographic database of household waste in the province of Settat using a Geographic Information System (GIS). The analysis of the maps made, the observation of photos of existing landfills, and a diagnosis of the landfills in the Settat province have shown a direct negative impact on the different vital axes.
