“…However, it was 17%-21% for rejects in the present work. Conversely, the moisture in other works conducted with lysimeters (with MSW as a substrate) was 52% [20], 41.1% [32], 41% [21], 40.4% [23], 32% [24] and 29.3% [25]. Therefore, in landfills with rejects from BMT plants, the waste mass reaches the FC later because of the lower moisture, and it would take longer to generate leachates.…”

“…pH usually remains constant when microbiological activity ceases, with neutral values of 6.5-7.0 [48], 5.7-8.0 [15], > = 7 [49], 5.8-6.8 [50] and 6.63-7.18 [25]. Nevertheless, replacing the recirculated leachate with tap water helped to maintain a neutral pH [20] and the pH of the leachate became neutral after the acidogenic phase and the non-degraded waste ran-off in the leachate [19]. Normally, pH initially lowers due to the acidogenic phase in works performed by lysimeters with fresh organic waste and pH values could drop to values of 5 or even lower within 30 days [22].…”

“…For example, Chung et al (2019) [19] analysed the influence of waste composition on landfill gas generation in a pilot-scale lysimeter using seven different waste types. Aljaradin and Persson (2016) [20] conducted a comprehensive study to monitor the emission potential from solid waste landfilled in Jordan using an anaerobic lysimeter. Godio et al (2015) [21] developed a small-scale lysimeter which was set up to simulate the biological processes that take place in a bioreactor landfill with rejects from an MBT plant under laboratory conditions.…”

This paper describes the laboratory-scale simulation of the behaviour of rejects from a biological-mechanical treatment (BMT) plant in Castellón (Spain). For this purpose, four lysimeters were built, with different densities. Simulations were carried out for 7 weeks and leachate recirculation was applied to two of them. The experimental results allowed us to determine: (i) dirt in fractions, which was relatively high (up to 15% in some fractions) due to biological processes; (ii) the field capacity for this waste with similar values to other works, which varied depending on the experiment; (iii) variation in the biomass percentage which lowered after experiments in all cases (59.5% lower on average), and the rejects’ calorific value was higher after experiments (28.2% on average); (iv) the evolution of leachate properties with or without recirculation, where percolation, in addition to the dragging of soluble materials, stabilised waste, which diminished its biological activity. Rejects’ increased calorific value will allow combustible material to be recovered in the future as a way to exploit the energy potential stored in landfills.

“…Hitherto lysimeter studies on municipal waste have been carried out in several research centres. These tests significantly differed in duration [2,5,7], size of the waste sample tested, purpose of the research, and scope of laboratory tests [8]. The size of the waste sample varied from 15 to 390 L [5,6].…”

The size and chemical composition of leachates migrating into the aquifer are dependent on the parameters of the waste and the storage conditions. Lysimeter studies allow us to determine the size and chemical composition of leachates as well as the leachate water balance. Lysimeter studies were conducted on a 230-L municipal waste sample for 6 months. During the tests, the specific electrolyte conductivity, pH, Eh, and temperature, as well as the chemical composition, microbiological analysis, and profiling of physiological population level using EcoPlate™ microarrays were measured in collected leachate samples. During the entire experiment, the amounts of inflow and outflow from lysimeters were measured. To assess the existence of significant differences in the chemical component concentrations in leachates, use of Principal Component Analysis was taken into account. The maximum EC value from leachate from the lysimeter was 33 mS/cm. High concentrations of ammonium ion (up to approx. 1400 mg dm −3), chlorides (up to approx. 6800 mg dm −3), and iron (up to approx. 31 mg dm −3) were observed in the effluents. The number of enterococci in May reached 53,000 cells/100 ml. By contrast, the number of these microorganisms was about 15,000 and 16,000 CFU/100 ml in January and April, respectively. Community-level physiological profiling indicates that the activity and functional diversity of microorganisms were higher in the leachate samples obtained in winter compared to effluents collected from lysimeters in spring.

“…Therefore it is vital to control the condition and volume of the water in a sustainable manner if conceivable contaminations are to be prevented. However, according to [3] there are numerous factors that compromise the quality of groundwater, including hazardous landfilling. [1] stated that over the last fifty years, Jordan has witnessed an upsurge in population.…”

The Use of GIS and Remote Sensing to Investigate Groundwater Vulnerability to Contamination and Surface Water Susceptibility to Pollution at Mafraq Dumpsite/Jordan

This study will evaluate how vulnerable groundwater is to contamination in Jordan, whilst further determining how prone to pollution surface water is. Situated upon what is believed to be one of Jordan's most important groundwater aquifers, the Mafraq dumpsite is understood to be a great hazard to the quality of water. With the ability to thoroughly assess both groundwater and surface water, the DRASTIC and SWSi indexes have been utilized throughout this study, providing further insight into whether the Mafraq dumpsite is located in a location where groundwater and surface water are vulnerable to contamination. The results gathered stress that the dumpsite is indeed located in an area where groundwater is at moderate risk of becoming contaminated. Additionally, surface water is at high risk of becoming contaminated due to the proximity of the dumpsite to the drainage system (Wadis) in the area. In conclusion, as the aquifer is used for both drinking and irrigation purposes, it is likely that human health is in jeopardy. Furthermore, it is apparent that the quality of both groundwater and surface water might be compromised as a result of the dumpsite.
