“…A significant difference occurred between the content of dissolved oxygen at p < 0.05, which showed a reduction of this determination in the examined waters below the analysed landfill. A lower average DO content in the water near the landfill was demonstrated by Gamar et al (2018). Other researchers (Diaz 2001; Kronvang et al 2005) have suggested that the presence of dissolved organic carbon and ammonium nitrogen could be a factor in reducing DO content in water (Guo et al 2010).…”

The study aim was to analyse the influence of a municipal solid waste landfill site in operation for over 10 years on the aquatic environment using multiple indicators. The water around the landfill area must be controlled due to the possibility of leachate interaction with harmful substances in the environment. The tests were carried out on the basis of 24 indicators, of which four were the most significant: depth of groundwater retention, ammoniacal nitrogen (NH 4-N), dissolved oxygen (DO), and polycyclic aromatic hydrocarbons (PAHs). The assessment of the quality of the surface water and groundwater and the analysis of the leachate pollution indices enabled the interpretation of the influence of a specific municipal waste landfill on the nearby water environment condition, despite not exceeding the permissible content at the highest average concentration of NH 4-N at 1.34 mg L −1. The differences were significant at the level of p < 0.05 in the content of DO in the water below the landfill. The concentration of NH 4-N in the groundwater below the landfill was statistically significantly correlated with the depth of the groundwater deposits (r = 0.609). Similarly, the surface water below the landfill site showed a statistically significant relation in the piezometer, which was also below the landfill, to ammoniacal nitrogen (r = 0.749). This result confirmed the statistically significant differences in the aquatic environment and the correlations with NH 4-N and that, below the landfill, the penetration water seepage is moderate with a low waste accumulation not exceeding 10 Mg per day.

“…The detection in the region of the city of El Hajeb of significant levels of heavy metals and metalloids in waters destined for human consumption has led to the realization of a study to identify potential risk areas. This area has already been the subject of a detailed potential investigation program including:  A study characterizing the leachates generated by the wild landfill of the city of El Hajeb (Gamar et al,2017a(Gamar et al, , 2017b, 2017c & 2017d),  A study of the physicochemical quality of groundwater adjacent to the same landfill (Gamar et al, 2018).…”

“…Previous studies investigated groundwater quality and salinization on the Tadla plain (Oum Er-Rbia basin in Figure 2a) and linked water quality deterioration to excessive use of organic and inorganic fertilizers and irrigation wastewater [36][37][38][39][40]. In the Middle Atlas and on the Saïss plain (Sebou basin in Figure 2a) water contamination from anthropogenic sources was identified [41]. While intense agricultural activity has caused nitrates to increase (up to 180 mg/L) in the Saïss aquifer, waters from the Middle Atlas still have good quality.…”

In semi-arid areas, many ecosystems and activities depend essentially on water availability. In Morocco, the increase of water demands combined to climate change induced decrease of precipitation put a lot of pressure on groundwater. This paper reports the results of updating and evaluation of groundwater datasets with regards to climate scenarios and institutional choices. The continuous imbalance between groundwater extraction and recharge caused a dramatic decline in groundwater levels (20 to 65 m in the past 30 years). Additionally, Morocco suffers from the degradation in groundwater quality due to seawater intrusion, nitrate pollution and natural salinity changes. Climate data analysis and scenarios predict that temperatures will increase by 2 to 4 °C and precipitation will decrease by 53% in all catchments over this century. Consequently, surface water availability will drastically decrease, which will lead to more extensive use of groundwater. Without appropriate measures, this situation will jeopardize water security in Morocco. In this paper, we zoom on the case the Souss-Massa basin, where management plans (artificial recharge, seawater desalination, and wastewater reuse) have been adopted to restore groundwater imbalance or, at least, mitigate the recorded deficits. These plans may save water for future generations and sustain crop production.
