“…However, the characteristics of the waste, the landfill area, the prevailing climate, and the waste management method must be identical between the two landfills. The water balance method's application to the Deir Al Balah landfill between 1997 and 2014 by Abunama et al (2017) gave a leachate production ratio of 0.06 m 3 /T. The method yielded an error of 17.5% compared to the on-site measurements.…”

The estimation of leachate quantities produced in landfills is necessary to dimension the treatment plants allowing to reduce the polluting load of these effluents and consequently avoid their negative impacts on the environment. Different leachate quantification methods were used in this study to assess the leachate volume produced at the Oum Azza landfill. The water balance method give comparable estimations of leachate production to the Ouled Berjal landfill ratio. The first method showed average values between 487 and 495 m3/day for 2015, 2018, and 2019, and at the same time, the second method gave values between 470 and 477 m3/day for the same years. In contrast, the World Bank ratio showed high values that vary between 2260 and 2295 m3/day for 2015, 2018, and 2019. The on‐site data and the statistical analysis showed us that the World Bank ratio is not adapted for the estimation of the leachates produced in Oum Azza landfill, while the water balance and the ratio of Ouled Berjal landfill allowed to give comparable results to reality.

“…However, this quantity is not compately released. According to Abunama et al (2017), waste absorbs water until it reaches the waste's field capacity. This parameter can be defined as the maximum amount of water that can be retained in the body of the waste against the force of gravity.…”

“…When stored in an RTS, SW is usually compressed for its later disposal, which leads to the generation of large amounts of fresh leachate. This leachate is produced via biological and chemical reactions of the waste material (Abunama et al, 2017). Generally, leachate extracted from SW contains high concentrations of many nutrients, but also heavy metals, and even extremely toxic organic compounds such as organic phosphorus pesticides (OPPs), thus posing a serious threat to both the environment and human health (Renou et al, 2008).…”

The properties of leachate from refuse transfer stations (RTSs) in rural China was inde nite. In this study, a total of 14 leachate samples from RTSs in nine provinces of China were characterized for their pH, electric conductivity, chromaticity, concentration of organic substances, nitrogen distribution, volatile organic compounds (VOCs), organic phosphorous pesticide, and heavy metals. The structural composition of chromophoric dissolved organic matter (CDOM) was also determined. To evaluate the leachate pollution potential in this study, a leachate pollution index (LPI) was derived and used. Chromium (Cr) was the most polluting heavy metal present in rural leachate. Ethanol and ethyl acetate were the most frequently detected VOCs at high concentrations. Three-dimensional uorescence excitation-emission matrix spectra was used to characterize the CDOM. Three components, tryptophan (C 1 ), tyrosine-like (C 2 ), and humic and fulvic acid-like (C 3 ) substances were identi ed from all 14 samples. Tryptophan was the major component of CDOM and present in 45.7% of the samples by calculating the uorescence intensity percentage, on average. Pearson correlations revealed that the uorescence intensity of C 1 and C 3 was strongly related to soluble chemical oxygen demand and dissolved oxygen carbon, while C 2 had signi cant positive correlations with ammonia nitrogen and total phosphorus of the solid waste. This study provided detailed data and ndings that could serve as a preliminary basis for broadening options for the treatment and management of leachate from rural RTSs in China.

“…Evapotranspiration is also an additional essential contributor to leachate generation (Frikha et al 2017). Abunama et al (2017) reported that for the Palestine site conditions, almost 54% of the leachate originates from the initial moisture content of the stored wastes, whereas 31.7% and 14.3% are related to the infiltration and recirculation, respectively. Klimek et al (2010) indicated that the application of the surface capping system is particularly important for the amount of leachate generated.…”

“…Suitable quantification of leachate generation is crucial for the needs of proper landfill design as a particular basis for the correct selection of parameters of drainage systems or retention reservoirs for temporary storage of the leachate (Yildiz et al 2004 ). This is important in planning the amount of leachate that should be used during the recirculation (Abunama et al 2017 ). In reference to the above, there is a real need for developing efficient methods of leachate purification and environment-friendly management (Talalaj 2015 ; Smol et al 2017 ; Vaverková et al 2018 ; Talalaj et al 2019 ; Szymański et al 2018 ).…”

The idea of water balance calculations within the landfill is to determine the distribution of water input and output, and finally the volume of leachate generated. The scope of this data is essential for rational planning of water and wastewater management, and designing leachate drainage network and leachate treatment systems. The aim of this study was to assess the possible amounts of leachate generation regarding ten different scenarios of landfill sealing systems. The calculations were performed using the Hydrologic Evaluation of Landfill Performance (HELP) model. It was revealed that the greatest share among the components of water balance in the landfill has precipitation (on average 509 mm in the 5-year period of simulation), together with evapotranspiration (on average 391 mm in the 5-year period of simulation). The study shows that the minimum amount of leachate (797–803 m3/year) occurs when the best placement quality (=5) is regarded for the geomembrane installed in the bottom of the landfill. The maximum leachate generation (830 m3/year) was found for those scenarios in which only three layers of bottom sealing systems were adopted, with the worst placement quality (=1) assigned to geomembranes. The results of this study confirm that the application of multilayer sealing systems has visible impact on the reduction of leachate generation of around 33 m3/year.
